Expression Exchange
Bank on your ability to write equivalent expressions. Scholars use an interactive to create expressions using coins. They then convert these to algebraic expressions and figure out how to evaluate them. A game with various difficulty...

Equality Explorer: Two Variables
Solving equations in two variables can't be that much harder than solving equations in one variable. Using a balance interactive, scholars solve equations in two variables. They apply inverse operations by adding -x, -y, or -1 as...
PHET
Equality Explorer
Find the right balance between concrete and abstract thinking. After using interactive balances to explore inverse operations, learners solve multi-step equations with variables on both sides. Of course, they can still use the...
PHET
Equality Explorer: Basics
Not all interactives are made equal. Scholars use an interactive balance to explore the concept of equality. They place different objects on balances to determine the number of each object needed to balance the scale.
PHET
Area Model Algebra
Expand the pupils knowledge of using area models to algebra. The interactive allows learners to use the same procedure of getting partial products when multiplying multi-digit numbers to multiplying polynomials. Scholars see how the...
PHET
Area Model Multiplication
Develop a solid understanding of multiplication. The interactive provides opportunities for learners to continue building a deep understanding of multiplication. Pupils use the application to find the product of two numbers and find...
PHET
Area Builder
All that matters is the tiles. Pupils use the interactive to investigate the relationship between area and perimeter using tiles. The interactive has an explore and a game mode to accommodate different steps in learning. The game mode...
