Free Algebra Expressions Practice
Combining like terms is the algebra equivalent of organizing a messy drawer — you put the x's with the x's and the constants with the constants. This practice strips out distracting fractions and exponents so your student focuses purely on the grouping skill. The mental rule: 3x and 5x are like terms (both have x); 3x and 5 are not (one has a variable, one doesn't). Once like-terms grouping is automatic, distributing through parentheses and solving multi-step equations are tiny incremental steps from here.
