R ead
the number inside the square root sign.
"The number inside the square root sign is
16."
O rganize
the number into groups, starting with two groups of 2.
"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."
O rganize
the number into groups, starting with two groups of 2.
"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."
