Prime Factorization is also a way
to find out if a square is perfect or not.
Square root is the inverse (opposite) of squaring, for example:
5² = 5x5 or 25
√25 is 5 times itself has a product of 25
5x5=21 || √25=5
√25 is 5 times itself has a product of 25
5x5=21 || √25=5
Yesterday's Homework
Estimating in Fractions
√1: 1
√2: 1 1/3
√3: 1 2/3
√4: 1 3/3 = 2
√5: 2 1/5
√6: 2 2/5
√7: 2 3/5
√8: 2 4/5
√9: 2 5/5 = 3
√10: 3 1/7 ...
See any patterns? The denominator is how many spaces are in between the 2 closest perfect squares. The numerator is how many spaces the square root number took going to the left.

(This part gets confusing but I'll try to explain it as good as I can)
- make another number line with √1 to √25 square root numbers with one and a half (1 1/2) intervals
- write the fraction x fraction = 1-25
- on the bottom, write the decimal that is almost equal to 1, 2, 3, ... 25
- lastly highlight or box the perfect square numbers
* Don't forget to use ' ' the almost equal symbol.
