Tuesday, December 8th

Sixth Grade

We did not have class today because we had mass at 12:10. See you tomorrow!

Seventh Grade

Spelling - 1st two pages.

Grammar - We graded part of the punctuation packet. There will be a test on Friday over commas, quotations, underlining, end marks, and apostrophes.

Literature - Today, we read from "A Christmas Carol" by Charles Dickens. We will be finishing Treasure Island, but I wanted us to read the Dickens story before Christmas!

Math - We did not have math class today. Mass was at 12:10 and as our class was serving and reading at the mass, much of the class ate lunch early. We will pick up with math tomorrow!

Eighth Grade

Lessons 5-4 and 5-5. #2-24 evens on both lessons. 5-4 is adding polynomials and 5-5 is subtracting polynomials.

Here is an example of adding. Remember, you can just drop the parentheses and combine like terms, or write the second polynomial underneath the first, lining up the like terms and keeping any sign that is in front of each term with it.





On 5-5, you are subtracting polynomials. The trick with these is to make sure that you distribute the minus sign to all the terms in the parenthesis after the minus sign. Then, you will add the polynomials like above. Here is an example:


Notice the blue arrows at the top. They are pointing from the minus sign to each term in the second parenthesis. You can rewrite the problem up and down as shown. Notice that the terms in the bottom parenthesis now have opposite signs. Then, you will combine the terms. Also, notice that there is not an "x" term in the second parenthesis, so I moved the +8 to be under the +6. The most important thing is to line up LIKE TERMS. Do not try to add terms that do not have the exact same variable (or variables) with the exact same exponents.

The class worked very hard today and I appreciate it! Let's keep that effort up.

See you tomorrow!
