A warm-up for the start of class, before students play or start the worksheet. It reviews ratios and unit rates using things students see every day, then asks them to think ahead to the most common proportion mistake. Two tickets print on each page; cut along the dashed line. The answer key prints on its own page after it.
1. 2 lemons make 3 cups of lemonade. How many cups do 4 lemons make?
cups
2. The sign says 4 for $8. What does 1 cost?
$
3. One batch uses 2 cups of flour. How much flour for 3 batches?
cups
4.Think ahead: 4 pancakes use 2 cups of flour. Sam says 8 pancakes need 6 cups, "because 8 is 4 more, so add 4 cups." Do you agree? Why?
Answer Key: Entry Ticket
Kitchen Math
6 cups (twice the lemons, twice the cups)
$8 ÷ 4 = $2
2 × 3 = 6 cups
No. 8 pancakes is twice as many, so it needs twice the flour: 4 cups. Adding the difference breaks the ratio.
Quick read: 5 cups on #1 means the student added 2 instead of doubling. Students who agree with Sam on #4 are the ones to watch today; the worksheet's find-the-mistake problem (#12) is built for them.
