Seventh graders learn to simplify algebraic expressions by combining like terms — grouping terms with the same variable, like 3x and 5x, while keeping constants separate — a core algebra skill.
Students will be able to…
“3x + 4 + 5x + 2” looks messy. Can we make it simpler? Only certain terms can be combined — which ones, and how?
Project this and sort each term into x-terms (have the variable x) or constants (just numbers). Only like terms can be combined!
