Activity 1 Frisbee Throws
Six students were throwing frisbees on field day. Here is some information about each person’s first throw.

Andre’s frisbee went 4 times as far as Tyler’s did.
Complete the table with Elena and Tyler’s distances. Explain or show your reasoning.

Activity 2 Stone Towers
While on an outing, a group of friends had a stone-stacking contest to see who could build the tallest stone tower.
Andre’s stone tower is 3 times as tall as Diego’s, but Diego didn’t build the shortest tower.
The tallest tower is 4 feet and 2 inches tall and belongs to Tyler.
One person built a tower that is 39 inches tall.
Tyler’s tower is 5 times as tall as the shortest tower.
How tall is each person’s stone tower? Be prepared to explain or show your reasoning.
