Interpreting a Division Computation
Alignments to Content Standards:

Task
Use the computation shown below to find the products.
 $189\times 16$
 $80\times 16$
 $9 \times 16$
Solution

$189\times 16 = 3024$. The computation shows that $3024 \div 16$ is $189$ with a remainder of $0$. So it must be that $189\times 16 = 3024+0$.

$80\times 16=1280$. We can see this in the second step of the division algorithm.
 $9 \times 16=144$. We can see this in the last step of the division algorithm.

almost 5 yearsI love how this task asks for conceptual understanding of something usually taught as a rote procedure. To be successful with this task, students must make sense of the procedure and how place value is represented and abbreviated within it.

almost 5 yearsThanks for your comment! Let us know how it goes if you get a chance to try it with students.
