Georgia 3.PAR.3.4
The Standard
Use the meaning of the equal sign to determine whether expressions involving addition, subtraction, and multiplication are equivalent.
Georgia's K-12 Mathematics Standards · Use part-whole strategies to solve real-life, mathematical problems involving multiplication and division with whole numbers within 100.

What This Standard Means
What Students Need to Do
- Students find the value of expressions on both sides of an equal sign. They decide whether the number sentence is true and explain how they know.
What Mastery Looks Like
- Students correctly identify true and false equations with operations on both sides. They can find a missing number and explain that both expressions have the same value.
Common Misconceptions
- Students may think the equal sign means “write the answer next” rather than “has the same value as.” They may compare operations or numbers without calculating both sides.
How to Assess It
- Give an exit ticket: Circle each true equation: 6 × 4 = 20 + 4, 9 + 8 = 20 − 3, 7 × 5 = 30 + 4. Explain one choice.

Ways to Teach It
Build each side of an equation with counters or arrays, then place matching totals on a paper balance mat.
Ask students to explain why 5 × 4 = 13 + 7 is true without saying only, “Both equal 20.”
Play a card-matching game where students pair addition, subtraction, and multiplication expressions that have equal values.
Compare 4 boxes of 6 markers with 30 markers minus 6, then decide whether the supplies are equal.
