3. Objectives Content Objective
I See connection between multiplication and division problems
I will be able to solve division problems with 2 digit divisors
Language objective:
I will be able to explain to a partner how I can use a division problem to help solve a multiplication problem and in reverse.
Ex ÷ 20 = 6 so
6 X 20 = X

4. Vocabulary to Know
