SIXTH GRADE

Today we worked on prime factorization using factor trees. The class is making a "Forest of Factor Trees" on a small poster in class. There is no homework. They will finish these in class tomorrow!

SEVENTH GRADE

Math: Simplifying Exponential Expressions and Order of Operations. I made a video for you!

Geography: We finished talking about conflicts and the class took notes on types of regions. I also assigned each student a country. They will be researching the regions of this country over the next few days. There is no homework.

EIGHTH GRADE

Pre-Algebra: I made two videos today because I didn't get the video done for last night. The first one below is for the two-step equations assignment from Monday. The second one is for the adding and subtracting decimals assignment from today, Tuesday.


On the end of the second video, I was cut off before I could finish the equation. I was about to multiply both sides by 5/11. When you multiply -93/20 by 5/11, you can cancel the 5 and make it a 1 and the 20 and make it a 4. So you would multiply across and get -93/44 as the answer!

Algebra I: You are doing evens only on both sides. The only exception is you don't have to do the two fraction inequalities on the first side. I believe these are numbers 26 & 28. You need to do all the fraction ones on the second side....there you are eliminating the fractions by multiplying by the reciprocal. Remember, reciprocal just means to flip over the fraction. Don't multiply by the OPPOSITE reciprocal. That won't work. So, if the fraction is -3/4, you would multiply by -4/3.

I made these two videos for Pre-Algebra when they did inequalities in their last unit. So, instead of making new videos, I am just embedding these two for you! Remember, the only time things are any different when you solve inequalities, is when you have to multiply or divide BOTH sides by a negative number. When you do that, don't forget to flip the inequality sign!



See you tomorrow!
