DIVISION
TOPICS 7 and 8: Division
Domain: Operations and Algebraic Thinking
3.OA.2: Interpret whole-number quotients of whole numbers
3.OA.3: Use multiplication and division within 100 to solve word problems in situations involving equal groups, arrays, and measurement quantities, e.g., by using drawings and equations with a symbol for the unknown number to represent the problem.
3.OA.4: Determine the unknown whole number in a multiplication or division equation relating three whole numbers.
3.OA.6: Understand division as an unknown-factor problem.
3.OA.7: Fluently multiply and divide within 100, using strategies such as the relationship between multiplication and division or properties of operations. By the end of Grade 3, know from memory all products of two one digit numbers.

Lesson 7-3: Finding Missing Numbers in a Multiplication Table
You can use multiplication to solve division problems. Look at the grid below. Let's say you wanted to solve 20 ÷ 5 = ?. To do so, locate the 5 along the top blue row. With your finger, follow down the 5 row until you reach 20. Now slide your finger to the left until you hit the blue column. The number you are touching is the answer, in this case 4. So 20 ÷ 5 = 4. Give it a try! It is a helpful strategy!
Now that you have learned this strategy, use the Multiplication Grid below to solve more division problems!
