Rewrite Addition Problems as Multiplication Problems using the Distributive Property 6.NS.4 Quick Code LZ2581 Sadlier 6-5A 1/2014
Review…. What is the GCF of 24 and 9? GCF = 3 Think… 3 times what makes 24 and 3 times what else makes 9 24 1x24 2x12 3x8 4x6 9 1x9 3x3 24 + 9 = (3 x 8) + (3 x 3) (8 + 3) 3
Mary plans to buy 12 yellow flowers and 18 blue flowers for her mother’s party. How can she combine the flowers into equal sets to put into vases?
In this lesson you will learn how to rewrite addition problems as multiplication problems by using the Distributive Property.
1. List factor pairs 2. Find common factors 2. Find GCF 1, 2, 3, and 6
Factors are numbers that are answers to multiplication. . . . . . .
Mary plans to buy 15 yellow flowers and 18 blue flowers for her mother’s party. 15 yellow flowers + 18 blue flowers How can she combine the flowers into equal groups to put into vases?
15 yellow flowers + 18 blue flowers Common factors: 1, 3
The Distributive Property allows us to write an addition problem as a multiplication problem. vases 15 + 18 3(5) + 3(6) 3(5 + 6) flowers flowers
Mary decided to buy 25 yellow flowersand 30 blue flowers. Common factors: 1, 5
Mary can use 5 vases to divide the flowers into equal groups. 25 + 30 5(5) + 5(6) 5(5 + 6)
Step 1: Find the Greatest Common Factor of Both Addends; Step 2: Write each addend as a multiple of the GCF; Step 3: Use the Distributive Property to rewrite the expression. Rewrite using the Distributive Property 24 + 40 GCF = 8 24 = 8 • 3 & 40 = 8 • 5 So 24 + 40 = 8(3 + 5)
In this lesson you have learned how to rewrite addition problems as multiplication problems by using the Distributive Property.
