Teacher's field guide

What Students Need to Do: Students evaluate the expression on each side of an equal sign. They compare the results, decide whether the equation is true or false, and explain why.
What Mastery Looks Like: Students correctly evaluate each side using the proper order of operations. They label the equation true or false and support the decision with calculations or a clear comparison.
Common Misconceptions: Students may treat the equal sign as a signal to calculate only the left side. They may ignore operation order or assume an equation is true because both sides look similar.
How to Assess It: Exit ticket: Is 36 ÷ 4 + 7 = 5 × 3 true or false? Evaluate both sides and explain your answer.

Lesson moves

Build both sides of equations with counters on a balance mat, then record whether the quantities match.
Ask students to explain in writing why 6 × 4 + 3 = 30 − 3 is true without changing either side.
Give partners equation cards to sort into true and false piles, then have them check each other’s calculations.
Compare two snack-order calculations, such as 4 × $3 + $2 and $14, and explain whether the bill equation is accurate.
