1. Multiply using the area model

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

3. 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

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

5. 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 =
