Zach solved the problem
. Complete the following model with partial products to check Zach’s work with multiplication.
A large rectangle is broken into 4 smaller rectangles The top line is labeled 5 and 0.2. The left side is labeled 20 and 4. The rectangles are divided between those labels. The top left rectangle is labeled A. The top right rectangle is labeled B. The bottom left rectangle is labeled C. The bottom right rectangle is labeled D.
Drag values to the boxes to complete the partial products. Not all choices will be used.
The product for A =
The product for B =
The product for C =
The product for D =
Choose the words to complete the statement.
Zach’s work is
because the total of the partial products is
as the dividend.
