kk mr.harbeck dont get mad at me for not really knowing how to post something so im gonna put my scribe here.

The first part of class we pulled out our homework from yesterday. After we used these tiles to try to make a square out of 10 tiles.
But no one can do it until Mr.Hanly showed us how. He showed us that if it is 4x4 so that would make it a perfect square but if we had to do 3x3, We wouldnt be able to make it perfect, so we give it a mullet. Like if it didnt have enough to make it perfect, it would get a mullet.
For Example:

1.1x1
2.2?x2?
3.3?x3?
4.4x4
5.5?x5?
6.6?x6?
7.7?x7?
8.8?x8?
9.9x9
10.10?x10?

New Numbers for homework.
12,14,17

Make squares out of all the numbers

Next scribe is Jorel.
