Unit Description
This unit covers using variables in equations and inequalities. The unit covers using variables in problems that involve addition, subtraction, multiplication, and division. One lesson is devoted to using signal words to determine the operation. The final lesson focuses on inequalities with three variables.
Standards covered:
4.PRA.2. Use letters and other symbols (e.g., L, x) as variables in expressions and in equations or inequalities (mathematical sentences that use =, <, and >).
