Create a grid. Write one factor (in expanded notation) along the top. Multiply each expanded number in the top factor by each expanded number in the side factor. Add the totals from each box to get your answer. 80 x 30= x 30= x 4= x 4= 24 Write the other factor (in expanded notation) along the outer right side. 2, ,924 (86) (34) 86 x 34=2,924
Create a grid. Write one factor (in expanded notation) along the top. Multiply each expanded number in the top factor by each expanded number in the side factor. Add the totals from each box to get your answer. 30 x 40= x 40= x 5= x 5= 35 Write the other factor (in expanded notation) along the outer right side. 1, ,665 (37) (45) 37 x 45=1,665
Create a grid. Write one factor (in expanded notation) along the top. Multiply each expanded number in the top factor by each expanded number in the side factor. Add the totals from each box to get your answer. 300 x 7= x 7= x 7= 42 Write the other factor (in expanded notation) along the outer right side. 2, ,702 (386) (7) 386 x 7=2,702
Now Let’s Try One On Your Own!
40 x 20= x 20= x 4= x 4= ,152 (48) (24) 48 x 24=1,152 Great Job!!!
