Algebra 1

Equivalence

Rewriting expressions into equivalent forms is a central part of doing mathematics. In these lessons students investigate the concepts of variable, equivalent expressions and the distributive property. As they evaluate expressions, they can also observe patterns such as rate of change and order of operations in the results.
