There are 8 pencils in a box. AJ has 15 boxes of pencils.
How many pencils are altogether?

15 x 8 =

10 x 8 = 80

5 x 8 = 40

80 + 40 = 120

To solve this problem I had use place value partitioning, so there was 8 pencils in a box and there are 15 boxes of pencils. I split 15 which made a 10 and 5 then I multiplied 10 from 8 which was 10 x 8 and my answer was 80 then I multiplied 5 and 8 and my answer is 40 so 80 + 40 is 120 so AJ has 120 pencils altogether.
