Multiply using the area model

Let’s Review Write the expanded for the number using place value. 45 40 + 5

Let’s Review Use patterns to multiply. 6 x 5 = ? 30 6 x 50 = ? 300 6 groups of 5 hundreds is 30 hundreds or 3,000. 60 groups of 5 tens is 300 tens or 3,000. 6 x 500 = ? 3000 6 groups of 5 tens is 30 tens or 300. 6 groups of 5 ones is 30 ones. 60 x 50 = ? 3000

Let’s Review 43 x 6 = ? 6 40 + 3 6 240 18 = 258 Now I add the partial products. 240 + 18 I need to find 6 groups of 40 plus 6 groups of 3. I can use place value to break apart the 43.

What if both factors were 2 digit numbers 53 x 64 = ? 64 50 + 3 60 (50 x 60) 180 3000 (3 x 60) = 3,392 + Now I add the partial products. I can use place value to break apart the factors. 200 4 (50 x 4) 12 (3 x 4) + + + 3,392 =
