Activity Synthesis
“The numbers tell us how high each of these animals can jump.”
Ask students to decide if each of the following statements is true or false and share their responses and reasoning:
“A rabbit can jump 10 times as high as a dolphin.”
“A dolphin can jump as high as a frog.”
“What other comparison statements can you make about how high these animals can jump?”
30 seconds: think time
1 minute: partner discussion
Share responses.
“We are going to keep thinking about making comparisons in our first activity today.”
