Use base-ten blocks to represent each expression. Then, find its value.
Problem 2
Find the value of each expression. Use base-ten blocks if you find them helpful.
Activity 2 Different Ways to Show Division
Problem 1
Jada and Han used base-ten blocks to represent
Here is Jada’s work:
Here’s Han’s work:
Make sense of Jada’s and Han’s work.
What did they do differently?
Where do we see the value of
in each person’s work?
Problem 2
How would you use base-ten blocks so you could represent these expressions and find their value? Be prepared to explain your reasoning.
: Would you make 4 groups or groups of 4? : Would you make 6 groups or groups of 6? : Would you make 15 groups or groups of 15?
