Students explore perimeter. In this geometry and measurement lesson, students create squares and rectangles using given perimeters. Students construct four sided shapes with given perimeters using the computer program "Math Keys:...

Redecorate a classroom on a budget. Middle schoolers rebuild a classroom after a disaster. They conduct Internet research to determine construction supplies needed and the most cost effective way to reach the predetermined results. They...

Consider the relationship between side length and area as an input-output function. Scholars create input-output tables for the area of squares to determine an equation in the first installment of a three-part unit. Ditto for the area of...

Using their knowledge of right triangles, pupils find out how far a ship is from a light house. Class members determine how far around the world a ship would be sailing at a constant speed.

Students are introduced to the notion of surface area and volume. Students review surface area and volume by finding the area of a two-dimensional shape. They practice using the computer to create different surface area shapes.

Students solidify their understanding of the terms "circumference" and "rotation" through the use of LEGO MINDSTORMS NXT robotics components. They measure the circumference of robot wheels to determine how far the robot can travel during...
