21
Solving OneStep Equations Objective: To use algebra tiles to model and solve singlevariable, onestep equations ESSENTIAL UNDERSTANDING: Equivalent equations are equations that have the same solution(s). In lessons 21 thru 25, students learn to use the properties of equality and inverse operations to find equivalent equations, and thus, solutions.

QUIZ on sections 21 thru 24 

27
Solving Proportions Objective: To solve and apply proportions ESSENTIAL UNDERSTANDING: If two ratios are equal and a quantity in one of the ratios is unknown, the unknown quantity can be found by writing and solving a proportion. Solving a proportion using "crossmultiplication" is really just like using the Multiplication Property of Equality twice.
