Sixth Grade
Lesson 80. Tomorrow, we will have a test review and on Friday, the test. The end of the 9 weeks is Friday, so if you are missing assignments, you need to get those in!
Seventh Grade
Math - Map scale activity. Today, I gave the students laminated world maps and a list of cities to find the distance between. They used the scale on the map to discover how far it was from places like Mexico City to Philadelphia, or Cairo to Seoul. This fits in with the proportions chapter we've been working on.
We also had Junior Achievement today and it was a blast! The class continued with the budget game, making decisions that we adults make all the time. Go out to eat or save and eat at home? Choose the unlimited phone plan or a cheaper plan with fewer minutes? It was interesting to hear their choices when it was "their" money! They were so responsible!
Be sure to work on your research paper and if you want me to look over your bibliography, bring it tomorrow! The paper is due on Friday and is a BIG part of your grade. It will count TRIPLE in the Language Arts grade.
Eighth Grade
Pre-Algebra. Lesson 7-5. #2-10. Direct Proportion. I believe everyone in class was understanding how to do these. For those that were absent, set up the proportion with the information given. If it says something like, "15 apples cost $8. How much would 9 apples cost?" You would set it up like this:
Algebra 1. Lesson 6-11. #18-32. (All of the back but the word problems.)
Systems of Equations. Elimination. You can click on the picture to make it bigger. Remember, with elimination, you are going to add the two equations vertically, eliminating one of the variables. In order to do this, the terms with the variable to be eliminated need to be opposites. If they aren't already, as in the problem below, multiply by -1. Since both of the x terms were 2x, multiplying one equation by -1 makes that x-term now -2x. When you add -2x and 2x, they go away and you are left with -4y=4. Now you can just solve for y. Remember, sometimes you will be able to eliminate the y term and solve for x first and sometimes you will be able to eliminate the x term and solve for y.
I hope this helps!
