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.
