1 Multiplication & Division Aoife Whiteacre

2  Content Area: Mathematics  Grade Level: 3 rd  Summary: The purpose of this PowerPoint is to give students the ability to learn and solve multiplication and division equations interactively.  Objective: Given an equation, the student will be able to accurately determine the unknown number that makes the equation true with 100% accuracy.  Standard: CCSS.MATH.CONTENT.3.0A.A.4 Determine the unknown whole number in a multiplication or division equation relating three whole numbers.

3 Multiplication Reminders 4 x 3 = 12 1 2 3 3 groups of 4 = 4+4+4 = 12

4 Division Reminders 12 ÷ 4 = 3 12 divided by 4s = 3 groups 1 2 3

5 Let’s Practice!  6 6  40 40  56 56 8 x ___ = 48

6 CORRECT! 8 x 6 = 48 just as 48 ÷ 6 = 8. Great job!

7  8 8  10 10  15 15 5 = ___ ÷ 3 Let’s do another!

8 CORRECT! 5 = 15 ÷ 3 just as 3 x 5 = 15. Great job!

9  12 12  36 36  1 1 More practice! 6 x 6 = ___

10 CORRECT! 6 x 6 = 36 just as 36 ÷ 6 = 6. Excellent job!

11 Summary In conclusion, you just learned how to determine the unknown numbers to make the multiplication and division equations true. Just remember, multiplication and division are inverse operations. If you know one, you know the other!

12 Multiplication is the operation of repeated addition of the same number. Division is the operation of splitting a number into equal parts or groups. As always, PRACTICE, PRACTICE, PRACTICE!
