Christine wants to plant vegetables. She has

24 vegetables and wants to put them in 3 rows. How many vegetables will go in each

row?

I know I can use division to solve this problem because I am separating

something (vegetables) into 3 groups (3 rows).

Christine wants to plant vegetables. She has

24 vegetables and wants to put them in 3 rows. How many vegetables will go in each

row?

Make an array.Get out 24 tiles.

Start to arrange them in 3 rows.

Your TurnTake 12 tiles. Make as many arrays as you can. Draw each array on your grid

paper and label it with a division equation.

Your TurnOn your grid paper, draw the array, label it with a division equation, and find the

quotient for each problem below.

1. 18 ÷ 6 = ___ 5. 16 ÷ 4 = ___2. 15 ÷ 5 = ___ 6. 25 ÷ 5 = ___3. ___ = 6 ÷ 3 7. 20 ÷ 10 = ___4. ___ = 20 ÷ 5 8. 14 ÷ 2 = ___

How can I use an array to solve a division problem?

Exit TicketMatch the equation with the array, then find the quotient.

16 ÷ 4 = _____

_____ = 12 ÷ 6

_____ = 16 ÷ 2
