26 is written as (20 + 6) ÷ 2.

Question 3.

Nell draws the array below to find the answer to 24 ÷ 2. Explain Nell’s strategy.

Nell’s strategy is 24 ÷ 2 = (12 ÷ 2) + (12 ÷ 2),

6 + 6 = 12, So, 24 ÷ 2 = 12,

Explanation:

To find answer for 24 ÷ 2 Nell draws an array

his strategy is he divided 24 as 12 + 12 then has

divided with 2, So equation for Nell’s drawing is

24 ÷ 2 = (12 ÷ 2) + (12 ÷ 2), 6 + 6 = 12.

Therefore 24 ÷ 2 = 12.
