Explore rates, ratios, and the distance formula. Your students will calculate the speeds, distances, and times as the turtles race down the beach. Each turtle has a different rate of speed as they move across the sand. Students will make tables and graph to show each turtle's progress. Next they'll make predictions and discuss patterns in the tables and graphs. This is a great task for sixth graders and advanced
fifth graders. You may want to divide the tasks among your groups or allow each group to complete all of the task and share their observations with the whole class.
There are three extensions that allow you to scaffold the activity among your ability groups. Be sure to let me know how it turns out four you. Enjoy!
