Math in Our World: Frog Jumps

Charlotte estimated that she could jump the length of 5 craft sticks. Her first jump was 7 craft sticks long. Her second jump was 9 craft sticks long. Her third jump was 3 craft sticks long.

Today we played a game we called Frog Jumps. Charlotte imagined she was a frog jumping as far as her frog legs could stretch. We put down a piece of tape for the starting line and used craft sticks to measure the length of each jump. Before we started, Charlotte estimated how far she could jump. Her estimate is the first line of sticks in the picture. She took three jumps, measuring how far she jumped with sticks each time.

  1. What do you notice? What do you wonder?
  2. Show or tell what you see using pictures, numbers, or math words.
  3. What math questions can you ask about the picture? Answer all the questions you can!
  • Remember, the first line of sticks shows Charlotte’s estimate. That means it shows her best guess about how far she could jump.
  • Count and compare the number of sticks for Charlotte’s estimate and each of her jumps.
  • How do each of her jumps compare with her estimate?
  • Show your work to someone else, and explain your thinking. Did they understand?
  • Ask whether they have any other questions you can answer!

You can do this activity at home too! Use a line on the floor as a starting point. Estimate how far you can jump and mark it with sticks, shoes, blocks or tape. Then do three jumps and see how far you can jump compared with your estimate.
