CLIMBING MONKEYS
How To Use (video) | Launch Climbing Monkeys
Purpose
Exploring patterns of change in equations and graphs; modeling the climb or decline of the monkeys using two linear algebraic equations
Description
Students set the "climbing options" for two monkeys, and watch the monkeys ascend or descend palm trees. The vertical heights of the monkeys are graphed on an associated grid. Monkeys can climb up or down, move at different speeds, and start from different heights.
Pouring and Filling
How to Use (Video) | Launch Pouring and Filling
Purpose
Comparing and filling cylinders, cones, and spheres; comparing and filling a cube with a square pyramid
Description
Students explore the relative volumes of spheres, cylinders, prisms, pyramids, and cones. Each shape is virtually "filled" with water, and then "emptied" into one of the other shapes. For example, a student might fill a sphere, and empty its contents into a cone. Students may then hypothesize about the formula for the volume of a cone as a proportion of the volume of a sphere.
