In class this week we learned that squares have a special relationship between their areas and their side lengths. Specifically, since you multiply the side length times itself to get the area (you square the side length), you can also take the SQUARE ROOT of the area to find the side length (since squaring and square roots are INVERSES).
To find the square root of a number, you must find a number that you can multiply by ITSELF to give you the number under the square root symbol. For example, the square root of 16 is 4 because 4 times 4 (4 times itself) is 16. When a square root is equal to a whole number, we say that square is PERFECT. Examples of perfect squares are 1, 4, 9, 16, 25, 36, 49, 64, 81, 100, and so on. If a square root is not equal to a whole number then we say it is non-perfect and we must estimate a value that is close. This estimating of non-perfect square roots is what we practiced in class today. If you want more practice at home (so that you are preparing/studying for your quiz that's this Friday), you can click the link below for some practice problems. Remember, you can either use the number line to estimate OR you can try using the tiling method we learned in class. Link to practice: CLICK HERE |
