The About, For Teachers and Terms pages now say the same.
October 3, 2026
- New address: studentmathgames.com. The site has its own domain now. Old thecodingeducator.github.io links and bookmarks still work and forward to the new address automatically. If your school filters websites, ask your technology department to allow studentmathgames.com.
- New contact email: studentmathgames@gmail.com (on the Contact, Privacy Policy and Terms pages).
- Battle on the Coordinate Plane: the title screen, Standard and Hard now take place in a storm at sea: rain, lightning, crashing waves, searchlights and water plumes on the horizon, with weathered ships and a jolt when a shot hits. The boards stay light and easy to read, and Easy keeps its bright, calm look.
- Battle on the Coordinate Plane: students now get a gentle heads-up when they fire at a point with x and y swapped from an earlier shot (or the same point again). In Standard and Hard, some shots first ask which way the plane will turn at the x-axis, clockwise or counterclockwise. Hard-mode enemy shots are always given in words. The fleet bar no longer says SUNK before the sinking plays, the menu now pauses everything, keyboard ship-moving stops at the other ship with a clear message, the target stays pinned on screen on phones, the top bar fits on one line on tablets, and the everyday sounds are recorded sound effects.
- Battle on the Coordinate Plane: a miss now makes a "plop" sound, like something dropping into water.
- New game: Battle on the Coordinate Plane (grades 5–6). A sea battle against the computer where every shot is an ordered pair. Students hide two ships on the points of their own coordinate plane, type coordinates to fire, and watch a plane fly from the origin left or right for x, then up or down for y. On the computer's turn they must find its shot on their own board, with feedback that names the mistake (x and y swapped, wrong direction) and stronger hints each try. Three modes: Easy (first quadrant, 0 to 6), Standard (all four quadrants, −3 to 3) and Hard (a timer, typed ordered pairs, shots described in words with y sometimes first, and quick quadrant questions). Spanish, keyboard-only play, a teacher guide, a worksheet and an exit ticket are included.
October 2, 2026
- Spanish check across every game: filled in the last few English bits (Similarity Builder's Menu button and a few placeholder titles, Rooted to the Spot's end-of-match title, and Proportional Plates' Recipe/Order labels).
- Every game's top bar: the teacher buttons are now called Full Teacher Guide and Quick Teacher Tips and sit side by side, and Fullscreen is always in the top-right corner. Links on the home page, the For Teachers page and the printables say Full Teacher Guide too.
- Bank Shot teacher guide and teaching notes updated to describe the new wrong-answer flow: the red wedge with its gap or overflow, the sum card, the retry with a hint, the equation on a second miss, and timeouts counting as misses.
- Bank Shot: after a wrong wall answer, the ball now leaves the wall exactly along the edge of the red wedge (the typed angle), so the picture and the ball always match.
- Bank Shot: on easy holes the shot now really meets the wall at the angle the question asks about (it used to be rounded), so the diagram, the dotted line and the ball all agree.
- Bank Shot: in Hole-In-One Hero, running out of time now counts as a miss: the explanation card opens and the same question is asked again, instead of a wild shot.
- Bank Shot: a second wrong try on the same question adds the equation with a blank (like 180° − 80° = ?) under the hint.
- Bank Shot: the ball makes a sound and the "no entry" cover flashes when the ball hits it.
- Bank Shot: keyboard aiming now always starts pointing straight up, not at the cup.
- Bank Shot: after a wrong answer, the cup is now covered completely by a red "no entry" sign (instead of a striped pole), and the ball bounces off the edge of the sign.
- Bank Shot: new look for wrong answers. The student's number is drawn as a red wedge next to the known angle: too small leaves a gray "?" gap before the wall (or the right angle's edge), too big spills past it. A small card at the top adds the two angles and shows they miss 180° (or 90°), without giving away the answer.
- Bank Shot: after a wrong answer, the red shot line now stops at the wall too, just like the green line for a right answer.
September 30, 2026
- Bank Shot: the shot lines are always straight. Water currents, hills and bushes can still steer the ball, but the drawn angle lines no longer bend with them.
- Bank Shot: after a wrong answer the ball rolls a little slower (same path), so it's easier to watch where the typed angle sends it.
- Bank Shot: the round bushes on the course are smaller, leaving more room to play around them.
- Bank Shot: wrong answers now play out the student's own number. On a wall shot the ball rolls to the wall and leaves it at the typed angle (shown with a red arc, without giving away the correct answer); on a straight shot it rolls along the typed angle. When the ball stops, the explanation card opens, and then the same question is asked again with a hint for that question: supplementary angles add up to 180° (wall shots) or complementary angles add up to 90° (straight shots).
- Bank Shot: the question diagram has just one white dotted line, the ball's path, and the two colored angles meet exactly on it.
- Bank Shot: on every shot, the green line now follows the ball and stops the moment it touches a rail (straight shots no longer cut off early).
- Bank Shot: after a shot, the green line follows the ball's real path exactly and lies right on top of the white dotted line to the wall.
- Bank Shot: the green shot line no longer runs through rails. It stops at the first rail in its way.
- Bank Shot: on straight shots, the missing complementary angle can now be any whole number from 1° to 89°, on every hole.
- Bank Shot: the angle question now always shows up where you aimed. A ball starting right next to a rail no longer counts that rail as hit, and a shot a bush or slope would steer into some other wall now gets the straight-shot question instead.
- Bank Shot: a shot at a wall now asks for the supplementary angle (the ball's path and the wall make a straight line, 180°), and a straight shot into open green asks for the complementary angle (a right angle with the aim line as one side, 90°). The teacher guide's worked examples match.
- Bank Shot: after a shot, the game shows the exact angle diagram from the question, with the "?" filled in by the answer (green, or red when the answer was wrong).
- Bank Shot: the green shot line now sits exactly on the angle diagram: a wall shot comes in along the line between the two angles and stops at the wall; a straight shot runs along the side of the right angle. Both angles stay visible as the shot is hit.
- Bank Shot: in a wall question, the ball's white dotted path now runs right to the wall and is the line between the two angles.
- Bank Shot: after a shot, the green line now stops when the ball hits a second wall.
September 29, 2026
- On-screen number pads, joysticks and touch buttons now only appear on phones and tablets in every game. A laptop with a touchscreen used with a mouse or keyboard no longer shows them (most noticeable in Bank Shot).
- Similarity Builder: more fun to play. Jumps and landings kick up dust and squash and stretch the runner, speed lines show when you are flying along, and the double jump sparkles. A quick correct answer builds a gold-trimmed bridge with fireworks. The sky turns from day to sunset to dusk as you run through each level, and there are new rhythm rows of evenly spaced obstacles and construction pile drivers to run under or jump.
- Similarity Builder: birds no longer turn up right next to a platform, where they could hit someone standing on it, and low-flying birds, drones and helicopters are already low when they come into view instead of diving at the last second.
- Similarity Builder: obstacles are harder and more varied. The runner is faster, obstacles come in tighter clusters, boulders, logs, barrels, stumps and crates roll or hop toward you, and some birds, drones and helicopters fly low, so you jump those instead of running under them. Obstacle messages no longer pop up on screen.
- Similarity Builder: the "Leave this run?" box on the pause menu now works from the keyboard: arrow keys move between Yes, Exit and Keep Playing, and Enter or Space picks one.
- On phones: pressing GO on a menu now picks the highlighted choice. Touching the joystick used to count as a mouse touch, which cleared the highlight (most noticeable in Exponent Racer).
- Linear World Cup: solid black x- and y-axes now cross the field while students write their equation, and the axis numbers and lines disappear once the player dribbles up the field after a correct equation, and while the other team has the ball.
- Tip the Scales: in 1-Step and 2-Step Equations, multiplying now distributes right away (×2 turns x + 3 into 2x + 6), so no parentheses appear that can't be simplified. Parentheses and the Expand button stay in Variables Both Sides and Complex Equations.
- On phones: the top bar's buttons (All games, Fullscreen, Standards and the rest) work again in Bank Shot and Linear World Cup, which were swallowing every tap on the page. In Exponent Racer, Exponent Hoops and Let's Get to the Point, the joystick now moves through the menus and GO picks, just like the arrow keys and Enter.
- Tip the Scales: on a phone held sideways, the scale now gets its own column beside the buttons instead of shrinking to a thin line, in both Challenge and Sandbox.
- Laser Heist: a Menu button during the heist pauses the game, just like Esc, so students on phones and tablets can pause too.
- Bank Shot, Exponent Hoops, Laser Heist and Piggy Bank Math now play their sounds the same smooth way as Exponent Racer: no stutter on phones, and no missing sounds. Every game also shares one Fullscreen button and one set of on-screen controls, so a fix to one now reaches them all.
- On phones and tablets: the joystick, GO button and number pad now stay on screen in fullscreen, and they never cover the game (the number pad in Bank Shot and Linear World Cup used to overlap the bottom of it). In Similarity Builder the Jump button, and in Proportional Plates the arrow pad and Take / Cook / Serve button, now sit beside the game instead of on top of it.
- Exponent Racer: collecting a coin no longer makes the game stutter on phones, and the coin sound plays every time.
- Similarity Builder: the distance at the top now says "Distance 91 m", and the "bridge locked in" messages now read like "Truss Bridge locked in with scale ×2!", so no dash sits next to a number where it could look like a minus sign.
- Rooted to the Spot: the goalkeeper has two new warm-up moves: slow knee bends with his chest up, and a jump to hang from the crossbar with both hands.
- Rooted to the Spot: the goal now looks a little bigger on screen, and root questions keep their question mark on the same line as the root.
- Rooted to the Spot: three skills now: Squares and Square Roots (with the side of a square), Cubes and Cube Roots (with new cubing and edge-of-a-cube questions), and Estimating Square and Cube Roots, whose power-shot challenge asks which whole number is closest to a root. Regular shots have a yellow aiming circle that stays wider, so even perfect shots vary; power shots keep a tight green one.
September 28, 2026
- Rooted to the Spot: skills are now Squares and Square Roots (√81 and 9²), Side of a Square, Estimating Roots, and Cubes and Cube Roots, with new cubing questions like 4³ = ?. Power-shot challenges add more powers of ten, from √1,000,000 and √100,000,000 to ∛1,000,000,000, and the goalkeeper moves more naturally.
- Rooted to the Spot: regular questions now use 0–10 (cube roots 0–5), and the power-shot bonus questions are the real challenge: 11–16, cube roots of 6–10, and powers of ten like √10,000 and ∛1,000,000.
- Rooted to the Spot: after each right answer students can take a harder bonus question for a power shot; word problems and "is √50 closer to 7 or 8?" questions; wrong answers now name the specific mistake (like halving for a square root); announcer captions after every shot; and a rippling net and confetti for every goal.
- Rooted to the Spot: a saved shot now bounces or rolls away from the goal and can never cross the line after "SAVED" appears. The keeper's warm-up moves stay in the center of the goal, with a quicker shuffle out and back.
- Rooted to the Spot: while students aim, the goalkeeper now warms up like a real keeper, with gentle sways, quick side shuffles, small knee-high hops and glove claps.
- Exponent Racer: every wrong answer is now a real student mistake: multiplying the base by the exponent (34 → 12), swapping them (34 → 64), one factor too many or too few, making a negative exponent negative (2−3 → −23), multiplying the bases (23 · 24 → 47) and more. No more random numbers.
- Exponent Racer: in Maximum Velocity, traffic cars no longer appear on top of each other.
- Exponent Racer: the Second Chance rewind now stops just after the last question was answered, so it never shows that question's answer choices again.
- Skill pickers in Exponent Racer, Let's Get to the Point, Laser Heist, Proportional Plates, Similarity Builder and Rooted to the Spot now start with nothing checked, so students choose exactly the skills they want to practice.
- Rooted to the Spot: a city skyline now rises behind the stadium (glass towers by day, lit windows and blinking roof lights at night), and the goalkeeper takes slow side-steps while students aim.
- Rooted to the Spot: a new title screen (the camera sweeps around the stadium while the crowd does the wave), the net now holds every goal, students can power up right after answering, and the arrow keys move between the buttons on every screen.
- Pro Penalty Shootout is now called Rooted to the Spot. Old links still work. The keeper now catches the ball in his gloves (arms up, out in front, crouching, or at full stretch), leans side to side while students aim, and sometimes stays rooted to the spot. The aiming circle also starts bigger.
- Rooted to the Spot: the crowd is now thousands of real fans who jump and cheer after a goal and start the occasional wave. The referee stands more naturally and blows the whistle before every kick. Students click (or tap, or press the space bar) once to power up and again to shoot, and a new Menu button (or Esc) pauses the game to resume, restart the shootout, or change skills.
- Rooted to the Spot: scoring is easier. Every spot in the goal has a better chance, a less-than-perfect release costs less, and the aiming circle is smaller, so more shots go in.
- Rooted to the Spot: one level for everyone, with square roots to 13 and cube roots to 6, plus simple powers of ten like √100, √10,000 and ∛1,000. A shot that misses now says exactly how: wide, over the bar, or off the post. With the keyboard, press the space bar once to start the power and again to shoot.
- Rooted to the Spot: the scoring chance now shows live while students aim and power up, and it really is the chance of scoring. The keeper now catches shots hit straight at them or struck weakly.
- Rooted to the Spot: estimating questions now ask for both whole numbers a root is between, and include cube roots too (∛50 is between 3 and 4). Cube-root mistakes are explained with a 3D cube of little cubes, the √ and ∛ signs look like the ones in a textbook, and the goalkeeper and referee are more detailed, with the keeper ready, arms spread, while students aim.
- Area Artist: in the art studio, the Turn button is now called Rotate, the word students will use in geometry.
- New game: Rooted to the Spot, an 8th grade square roots game. Students earn each of five penalty kicks by answering a question, then aim and time their shot in a 3D stadium. Like Exponent Racer, students choose their skills: square roots, squaring numbers, the side of a square from its area, estimating square and cube roots between two whole numbers, and cube roots, with square roots to 13, cube roots to 6, and powers of ten like √10,000 and ∛1,000. A wrong answer shows why, with a square of unit squares, a cube of little cubes, or a number line, and the final screen lists every missed question with its answer. In English and Spanish, with a teacher guide, printable worksheet and exit ticket, and My Stats badges.
September 27, 2026
- The site now signs its games, guides and printables as Mr. H.
- New game: Area Artist, a 3rd grade multiplication game. Students multiply rows by columns (or find a missing side) to paint a hidden pixel-art picture one rectangle at a time. Product Picasso uses 1×1 to 5×5 with every square countable; Multiplication Monet goes up to 12×12. Students choose from 68 pictures in eight categories (animals, pets, space, nature, sports, fashion and style, objects and vehicles), build their own art in the studio, and keep everything in a gallery. In English and Spanish, with a printable worksheet and exit ticket.
- Proportional Plates is now in Spanish. A new 🌐 Español button in the top bar switches the whole game — menus, recipes, orders, hints, customers' reactions and the "let's fix it" explanations — and the choice is remembered.
- Every game is now in Spanish. Press 🌐 Español in the top bar of any game: Piggy Bank Math, Exponent Hoops, Exponent Racer, Linear World Cup, Let's Get to the Point, Laser Heist, Bank Shot, Similarity Builder, Pythagorean Platforms and Tip the Scales join Proportional Plates. The choice is remembered for every game on the device.
- Linear World Cup: on phones, the MENU button's "Yes, exit" and "Cancel" choices now respond to taps.
- Linear World Cup: a goal now looks like a goal — the ball disappears into the net as it crosses the goal line.
- Bank Shot, Exponent Hoops, Exponent Racer, Laser Heist and Let's Get to the Point: on phones, buttons near the bottom of the game screen are no longer blocked while the joystick or number pad is showing.
- Proportional Plates: customers who are almost out of patience now complain in funny, over-the-top ways ("I've aged 10 years!", "I could eat the table!") instead of showing symbols.
- Proportional Plates: muffins now look like real muffins — a paper liner and a golden, domed top.
- Proportional Plates: the "let's fix it" card now shows the recipe and the order side by side joined by the scale factor (like ×4), and writes the proportion out — recipe amount over recipe size = order amount over order size — with the scale factor drawn between the tops and between the bottoms.
September 26, 2026
- Proportional Plates: the chef can cook several orders in a row and carry two plates at once, with a trail to each table; extra plates wait on the kitchen counter to be picked up. A wrong order now goes back on the rail to be remade, and customers only storm out when their patience runs out. Level 1 uses easier numbers, the recipe pictures stay inside their boxes, and happy customers sometimes say "¡Delicioso!"
- New: free printable worksheets and exit tickets for every game, each with an answer key. Find them on each game's teacher guide and on the For teachers page. Exit tickets print two to a page.
- The home page and For teachers page now list grade 8 topics first (Lines and slope, Geometry), then work down to grade 2.
- Teacher guides for every game, plus a new For teachers page that organizes the games by grade and Common Core standard.
- Tip the Scales: fractional blocks are now drawn as a whole block with only the fraction filled in, so ¼x looks like a quarter of an x-block and the label always fits.
- Tip the Scales: the Expand button now appears only in Variables Both Sides and Complex Equations, with a one-time pop-up that points to it and explains Expand and Factor.
- Phones and tablets: every game page now fits on one screen with no scrolling, and the game sits clear of the on-screen joystick or number pad.
- My Stats is organized by game and in total, and every game page has a My stats pop-out.
- Reset progress has its own button with a 5-second countdown before anything is erased.
- Every game now fills the screen on a computer; Standards and Teaching notes open as pop-outs.
- Every game can be played with the keyboard alone (the mouse still works).

- Proportional Plates: clearer question pictures for every kind of order.
September 25, 2026
- New game: Pythagorean Platforms, a jungle game for the Pythagorean theorem with rope-length and platform-distance swings.
