The activities explore the calculations of squares and square roots to solve equations involving right triangles. Explore both the video and the interactive components of this resource.

This virtual pan balance lets students compare algebraic expressions. Weigh and compare the expressions by entering them on either side of the balance. Practice arithmetic and algebraic skills, and investigate the important concept of equivalence.

Use this virtual scale to strengthen your understanding of numerical expressions and equality. Instructions for exploring this tool are below the scale.

Explore this balance tool using shapes of unknown weight. Challenge yourself to find the weight of each shape. Instructions for exploring this activity are below the scale.

In this video, students learn how writing an algebraic equation can help solve a real-life problem, such as when to buy cat food. There are support activities as well.

Use distance and speed of travel to solve a real-life problem. This interactive exercise focuses on using what you know about the Pythagorean theorem and rate of change to make a prediction about whether Ben or Dan will get their tacos first and then requires completing the calculations to see if your prediction was accurate.

An algorithm is a method of solving problems both big and small. Though computers run algorithms constantly, humans can also solve problems with algorithms. David J. Malan explains how algorithms can be used in seemingly simple situations and also complex ones.
