Sixth Grade
Today the class practiced more division - with money and then with averaging. We had a little fun finding the average class height and discussing why it's reasonable. Then we worked a little on division word problems and figuring out what the remainder might mean. There are two pages for tonight - one is front and back, division with money and averaging - the other is one-sided and contains 8 word problems. We did two of these together.
Seventh Grade
Math - Today we began working with graphs and made a bar graph by picking 10 random states and graphing the population density of each. Be sure to finish your graph by tomorrow.
Geography - We continued our discussion of population density and other population factors by reading Chapter 3, Section 1. We also used our population density information to color a map of the US. Tomorrow, we will color another map with more detailed information. Tonight, finish coloring the map and be sure to define the words at the end of Section 1.
Eighth Grade
Pre-Algebra - Computation Review. Many students finished in class, but some need to complete the problems at home.
Algebra I - pg.60-61 handout: #7-24 ALL, 36-88 EVENS. For #36-46 remember that you are multiplying the number on the outside by both of the things on the inside.
-3(-5 - 2x) = 15 + 6x (-3 times -5 = 15 and -3 times -2x = +6x)
For #48-58, you are doing the reverse and "pulling out" or factoring out what the two terms have in common. For example:
3x + 9
Both terms can be divided by 3 so they have a 3 in common. Divide each term by 3 (that's the same as saying "factor out" or "pull out" a 3) and put the 3 on the outside of the parenthesis. What's left inside is whatever is left after dividing by 3. The answer would be:
3(x + 3)
3x divided by 3 = x
9 divided by 3 = 3
Remember, you know you factored right if you use distributive property and get the original expression.
