5. Application Problem
(6 minutes)
20 children play a game. There are 5 children on each team.
How many teams play the game?
Write a division sentence to represent the problem.
(Use the RDW process to show your solution)

6. Concept Development
(35 minutes)
What is the total number of children and total number of dots?
What it the total number of children on each team and the
number of dots in each row?
What is the total number of teams and number of rows?

7. Concept Development
(35 minutes)
Now, using your personal white boards,
draw an array that shows 8 ÷ 2 = 4.
Draw an array that shows 18 ÷ 6 = 3.

8. Concept Development
(35 minutes)
Now draw an array that shows the division
sentence 15 ÷ 3 = 5, where the quotient- that
means the answer- represents the size of the
group.
Write a division and multiplication sentence for
the array.
Where is the quotient in the multiplication
sentence?
Circle the size of the groups in both problems.

9. Concept Development
(30 minutes)
Draw an array for 4 rows of 2. What is the
quotient?
Draw an array for 7 x 3 = 21. How many groups
are there and how many are in each group?
Explain to your partner how the factors in a
multiplication problem can help you find the
quotient in division.

10. Concept Development
(35 minutes)
______ X 3 = 24
Skip count and track the number of 3’s to solve.
How many 3’s make 24? Answer in a complete
sentence.
Write a related division sentence where the
quotient represents the unknown factor.

11. Concept Development
(35 minutes)
Did you write 24 ÷ 3 = 8? Good job!
24 divided into 3 makes how many groups?
How are the unknown factor and the quotient
related?
Repeat using 2 X ____ = 18 & 18 ÷ 2 = _____
And _____ x 9 = 27 & 27 ÷ 9 = _______

12. Concept Development
(35 minutes)
_____ x 3 = 24 and 24 ÷ 3 = _____
True or false: both equations ask “How many
threes are in 24”?
