"The number inside the square root sign is 16."

 

"I need to break 16 into groups. I am going to make 16 circles and see if I can put them into groups. Let's see, 2 groups of 2 is 4. But that doesn't use up all my circles. 3 groups of 3 is 9. I still haven't used up all my circles. I'll keep going. 4 groups of 4 is 16. There, I have used up all 16 circles."

"I need to check and make sure it adds up. Let's see. Four groups of four would be, 4, 8, 12, 16. Yep, it adds up. Four groups of four is sixteen."

T ie down the answer, or continue grouping.

"I know that I have found the answer because I started with the number inside the square root, 16, and used that number to make four equal groups of 4."

I dentify the square root by circling/counting the total number of groups.

"Now I need to identify the square root. I am going to do that by counting the total number of groups I have made from 16. I am going to circle each group as I count. I made 1, 2, 3, 4 groups. The square root of 16 is 4."

T est the answer by counting.

"I need to check the answer by counting. I will count each of the circles in the groups to make sure that they add up to the number in square root sign. I counted all the circles and I have 16 circles in the 4 groups that I made. 16 is the number in the square root sign. So, the square root of 16 is 4."
