AJ has 15 boxes of pencils.
How many pencils are there altogether?
15 x 8 = ??
10 x 8 = 80
5 x 8 = 40
80 + 40 = 120
To solve this problem, I used place value
partitioning. I multiplied 10 by 8 and I got 80
as the answer. Then, I multiplied 5 by 8 and
I got 40 as the answer. Then I added 80 and 40
and I got 120. So AJ has 120 pencils
altogether.

Well done AJ. You have given a very good explanation on how you solved this problem. Keep up with your good work.
