11)What is the square of each number?
a)9
-The square is 81. Because you multiply it by itself.9 squared or 9x9=81

b)11
-The square is 121. Because you multiply it by itself.11 squared or 11x11=121

Vicky's Scribepost, December 2nd

Today in math Ms. Usiskin told us to do the questions in the text book, or we can finish our number line inside our foldables. I chose to do the number line.

Sorry for the super bad quality, the quality got bad when I put it in blogger... idk why. & sorry if the pictures are so small,if i made them any larger it would've been too blurry to see. I probably didn't complete this part of my foldable either. Sorry :)

Well, I didn't know what else to label, so thats all I could think of. Sorry if its so plain.

COMMENT PLEEASE ! :)

Today in Math class, Ms. Usiskin handed out are math quiz she graded it with letters:







Ms. Usiskin was talking about it for a bit, then we had to try to revise our quiz.



Then we started to go over the homework, which was the foldable on the numberline. Then after that we started to talk about "square roots". Which is the second flap in the first foldable.





sorri if i didn't say everything we did in class i kinda forgot.


THE HOMEWORK: Finish revising quiz and finish your number line (with fractions, with decimals and with your calculator) . REMEMBER to press SQUARE ROOT for the calculations.
