Draw a pictorial representation of the division and multiplication problems using a tape diagram.
a. 8 ÷ 2
b. 3 × 2
1. Build a tape diagram to represent units.
2. Divide the units into three equal groups.
3. Write an expression to represent the process you modeled with the tape
4. Evaluate the expression.
5. Use your squares to demonstrate what it would look like to multiply 3 by 3.
6. Alter our original expression 9 ÷ 3 to create an expression that represents what we did with the tape diagram.
7. Evaluate the expression.
8. What do you notice about the expression of the tape diagram?
9. Write a number sentence, using variables, to represent the identities we demonstrated with tape diagrams.
Use the variable tiles you were provided to demonstrate this number sentence with a series of tape diagrams.
Learn why multiplication and division are inverse operations.
1. Fill in the blank to make each number sentence true.
a. 12 ÷ 3 × ____ = 12
b. f × h ÷ h =
÷ 15 = 45
d. ___ ÷ r × r = p
