20 ÷ 2 = 10

Decompose and Divide

12 ÷ 2 = __

Decompose 12 in 10 and 2, because 10 + 2 = 12

Now, I am going to divide each one of the numbers by 2:

(10 ÷ 2) + (2 ÷ 2) = ___

5 + 1 = 6

Concept Development

White board

Let’s use this array to help us solve

24 ÷ 2 = ____.

(20 ÷ 2) = 10

(4 ÷ 2) = 2

How many twos are above the line?

How many twos are below the line?

10 twos

2 twos

First, let’s write division equations to represent the part of the array above the line and the part of the array below the line.

Let’s use this array to help us solve

24 ÷ 2 = ____.

(20 ÷ 2) = 10

(4 ÷ 2) = 2

First, let’s write division equations to represent the part of the array above the line and the part of the array below the line.

Write this as the addition of two divisions

(20 ÷ 2) + (4 ÷ 2) = ___

10 + 2 = 12

Then, 24 ÷ 2 = 12
