About this resource
Description
Multiplication and division are two sides of the same fact. This 3.OA.7 Common Core activity helps 3rd and 4th grade students find the unknown number in multiplication and division equations within 100, whether the missing number comes first, in the middle or after the equal sign.
In Solving Multiplication, children match 12 lettered snowflake problem cards to 12 fish answer cards. Each problem, like 6 × ? = 42 or ? ÷ 5 = 9, has exactly one fish card that makes it true, so students think about the related fact instead of guessing. They record each answer on the recording sheet, then check their work with the answer key. Print the cards one-sided and make a few straight cuts on the dashed lines. A 3rd grade practice page gives six new problems, each with a check problem that uses the opposite operation.
What’s Included
- A colorful cover page
- A How to Use page with simple steps and prep tips
- 12 snowflake problem cards and 12 fish answer cards
- A recording sheet for all 12 problems
- A 3rd grade practice worksheet: solve, then check with the related fact
- A recording sheet answer key and a practice answer key
Why This Activity Helps Kids
- Finding the unknown in every position builds real fluency with multiplication and division facts.
- Checking each answer with the opposite operation shows how multiplying and dividing are connected.
- Matching cards turns fact practice into a game that children want to play again.
Ideas for Teachers and Parents
Use the cards at a math center, with a partner or as a quick warm-up before a lesson. Time a round and try to beat it the next day, or have students write their own problem card for a classmate. Send the 3rd grade algebra activity home for extra fact practice. Come back to this 3.OA.7 Common Core activity whenever students need a fun review of multiplication and division within 100.
