3. Model with Arrays How can I use an array to solve a division problem?

4. 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?

6. I know I can use division to solve this problem because I am separating something (vegetables) into 3 groups (3 rows).

7. 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.

15. 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? 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 3

16. 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? 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 Since there are 8 tiles in each row there will be 8 vegetables in each row. 3 8

17. Your Turn Take 12 tiles. Make as many arrays as you can. Draw each array on your grid paper and label it with a division equation.

18. Your Turn On 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 ÷ 37. 20 ÷ 10 = ___ 4.___ = 20 ÷ 58. 14 ÷ 2 = ___

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

20. Exit Ticket Match the equation with the array, then find the quotient. 16 ÷ 4 = _____ _____ = 12 ÷ 6 _____ = 16 ÷ 2
