Today, Mr. Backe' told us some things about square roots.
We started the class learning some things about the squares we made for our previous classes (see the previous scribeposts.).
Here are a few things that we did:
To find the area(the amount of space inside) of a square, we need to find out the length and width and multiply them. Because the sides of a square are all equal, we only need to find one side and multiply it by itself to find the area.
We also learned that not all squares are perfect squares. Only squares with whole numbers as their sides are perfect squares.
We then learned about square roots. A square root is a number that can equal a given number by multiplying itself by itself.
Square root of 9 is 3
You can find a square root on a calculator by pressing the √ button and the number you want to find the square root of.
Our homework is to find the square roots of all numbers from 5 to 9.
I hope you guys liked my scribepost! Please leave a comment.
