Question

which repeated addition sentence matches the array?
options:
2 + 2 + 2 + 2 + 2 = 10
2 + 4 + 2 + 1 + 1 = 10
4 + 4 + 2 = 10

Explanation:

Step1: Count rows/columns in array

The array has 5 rows, each with 2 squares.

Step2: Write repeated addition

Add the number of squares per row 5 times: $2 + 2 + 2 + 2 + 2 = 10$

Step3: Verify other options

The second option uses non-equal groups, the third uses inconsistent group sizes, which do not match the uniform array.

Answer:

2+2+2+2+2=10
