## Activity 1 Frisbee Throws

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

Elena’s frisbee went 3 times as far as Clare’s did.

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.

Elena came along and built a tower that is 5 times as tall as Diego’s tower. Is Elena’s tower more than 6 feet? Show your reasoning.

## Practice Problem

## Problem 1

Diego saw a snake that is 9 inches long at the pet store. The world’s longest snake, a python, is 10 yards long. How many times longer is the python than the snake Diego saw? Explain or show your reasoning.
