3. 19 x 6 =154 Factors Product Linear Expand ed Strategy Multiplication Strategies Objectives: I can multiply multi-digit whole numbers using multiple strategies. In this strategy I will expand the factors, multiply the factors, and write the product in a line. Example: 37 x 5 = 37 x 5= (30 x 5) + (7 x 5) = 150+ 35 = 185

4. 24 x 3 = 24 x 3= (20 x 3) + (4 x 3)= 60 + 12 = 72 69x 8= 69x8= (60x8) + (9x8) = 480 + 72 = 552 Now lets do this equation together 62 x 4= Examples:

5. Vertical Expande d Strategy 2 digits by 1 digit In this strategy I will expand the factors, multiply the factors, write the product vertically, and then, I will add the product to get the final product. 23 x 6= 23 x 6 18 (6 x 3) + 120 ( 6 x 20) 138 49 x 5 45 (5 x 9) +200 (5 x 40) 245 49 x 5=

6. Now lets do this one equation together 82 x 6 = Examples: 45 x 12 10 (2 x 5) 80 (2 x 40) 50 (10 x 5) + 400 (10 x 40) 540 2 digit by 2 digit

7. Grid Traditiona l Strategy In this strategy I will use a grid to multiply. The grid breaks apart the factors into tens and ones. 47 x 32 = 40 7 3012002101410 2 80 14 94 12802241504
