Balance the Equations, Multiply and Divide

Written by Adi Ackerman, Head Teacher

"Balance the Equations, Multiply and Divide" is written for 3rd Grade (Ages 8-9), and it covers Common Core 3.OA.A.4. If your little one is a year younger but already steady on division, the page still works. You may just need to read the instructions out loud. And if they are older and missing dividend or divisor (basic facts, 1-10) never quite stuck, this is a short review rather than busywork.

Balance the Equations, Multiply and Divide

3rd grade math worksheet: find the number that balances 10 equations with an operation on each side, like 2 × 5 = 80 ÷ 8. Answer key included. Part of our missing dividend or divisor (basic facts, 1-10) division collection. Aligned to Common Core standards.

How do I use this worksheet?

Remind your child that every division fact has a matching multiplication fact, so 42 ÷ ? = 7 can be read as 7 × ? = 42. Check with the answer key.

What students will practice

  • Students will learn that the equal sign means both sides have the same value.
  • Students will find the value of the side with no box.
  • Students will write the number that balances equations like 2 × 5 = 80 ÷ 8.

FAQ

How do I use this missing dividend or divisor (basic facts, 1-10) worksheet?

⌄

Remind your child that every division fact has a matching multiplication fact, so 42 ÷ ? = 7 can be read as 7 × ? = 42. Check with the answer key.

What does this worksheet teach?

⌄

Find the number that balances 10 equations with an operation on each side, like 2 × 5 = 80 ÷ 8. The equal sign means both sides have the same value. Find the number that makes the two sides equal. The directions on the page read: Find the value of the side with no box. Then, write the number in the box that makes the other side equal to it. An answer key is included.

Can I use this missing dividend or divisor (basic facts, 1-10) worksheet for homeschool or classroom?

⌄

Yes, both. We made it for 3rd Grade division, and the page works the same whether it lands on a kitchen table or a center rotation. At home, most families go through it together and talk the answers out loud, and that talking is where most of the learning happens with missing dividend or divisor (basic facts, 1-10). In class it runs well as independent work while you pull a small group. Print one copy or thirty, whichever the day needs.

What is the difference between a missing dividend and a missing divisor?

⌄

A missing dividend problem, like a box divided by 6 equals 7, asks for the total. A missing divisor problem, like 42 divided by a box equals 7, asks for the number of groups or the size of each group.

How do students find a missing dividend?

⌄

Multiply the divisor by the quotient. For a box divided by 6 equals 7, 6 times 7 is 42, so the dividend is 42. Find the Unknown Dividend prints this step at the top.

What does it mean to balance an equation?

⌄

The equal sign means both sides have the same value. In 2 times 5 equals a box divided by 8, the left side is 10, so the box is 80. Balance the Equations, Multiply and Divide has 10 of these.

Is there an answer key for each worksheet?

⌄

Yes. All 11 sheets have an answer key.

What division concepts should third graders learn?

⌄

Third graders learn that division means splitting into equal groups or finding how many groups. Per CCSS 3.OA.A.2, they should interpret whole-number quotients and solve division word problems within 100. They should understand division as the inverse of multiplication.

How do you introduce division to third graders?

⌄

Start with sharing equally: give 12 items to 3 people, how many does each get? Use concrete objects, then pictures, then equations. Worksheets with visual division (circling equal groups) bridge the concrete-to-abstract gap effectively.

How do I know if my child is fluent with division facts?

⌄

Fluent means a fact comes quickly and correctly without counting. The two minute drills hold 30 or 36 facts, and Division Fact Fluency Check, 40 Facts lists each missed fact to practice. CCSS 3.OA.C.7 expects fluency within 100 by the end of 3rd grade.
