Skills Covered

  • Understand the equal sign as "has the same value as"
  • Find the value of a multiplication or division fact
  • Decide whether an equation with × and ÷ is true or false
  • Compare two facts with = or ≠
  • Find the missing number that makes both sides the same
  • Write equations with two facts of the same value

How to Use This Pack

Five pages on the equal sign with multiplication and division on both sides. Page 1 hangs a fact on each pan of a balance, such as 6 × 4 and 3 × 8 or 20 ÷ 4 and 10 ÷ 2: students write the value of each side under its pan and circle equal or not equal, with a worked example first. Page 2 has eight equations to mark True or False, like 24 ÷ 4 = 2 × 3 and 9 = 72 ÷ 9, then two to explain: 5 × 6 = 6 × 5 (true) and the trap 8 ÷ 2 = 2 ÷ 8 (false, because order matters in division). On page 3 students write = or ≠ between ten pairs of facts, then write × or ÷ in two boxes to make six equations true, such as 8 ÷ 2 = 2 × 2. Page 4 has ten equations with a missing number, like 4 × 6 = 8 × __ and 18 ÷ __ = 9 ÷ 3; students write the number and the value both sides share. Page 5 asks for two × facts and two ÷ facts that make 8 and 6, joined into a true equation, then whether Sam and Rosa are right.

In the Classroom

Before page 1, build both sides with counters: 4 rows of 6 on one desk and 3 rows of 8 on another, and count to see they have the same value. Then share 20 counters among 4 children and 10 counters between 2. Read 8 ÷ 2 = 2 ÷ 8 on page 2 aloud and ask the class to share 2 crackers among 8 children: does each one get 4? Page 5 makes a good partner task: students check each other's facts for 8 and 6.

At Home

Say an equation out loud, like "3 times 4 equals 24 divided by 2", and ask whether it is true. Then let your child make one up for you, true or false. Sharing snacks into equal piles is a quick way to check a division fact.

Tips for Success

  • Read the equal sign as "has the same value as"
  • Find the value of each side on its own, then compare the two values
  • You can switch the factors in multiplication, but not the numbers in division: 8 ÷ 2 is not 2 ÷ 8
  • Any number times 0 is 0, and any number divided by itself is 1
  • For a missing number, work out the side with no blank first

Common Core Standards Alignment

This pack supports the following Common Core State Standards for Mathematics:

  • 3.OA.A.4 Solve for the missing number in multiplying or dividing equations, such as 7 × ? = 42 or ? ÷ 3 = 6.
  • 3.OA.C.7 Multiply and divide to 100 fluently with strategies, and by year's end instantly recall every product of two single-digit numbers.

True or False: Multiplication & Division

3rd Grade

A 5-page equal sign pack for 3rd grade with multiplication and division on both sides. Hang a fact on each pan of a balance, write the value of each side and circle equal or not equal, circle True or False for equations like 24 ÷ 4 = 2 × 3 and 8 ÷ 2 = 2 ÷ 8 and tell how you know, write = or ≠ between two facts, write × or ÷ to make an equation true, find the missing number in equations like 35 ÷ 5 = 1 × __, write your own facts for 8 and 6, and decide whether two children are right. Every page comes in color and in black and white. Answer keys included.
