Tuesday, January 18th

Sixth Grade

Literature - You will NOT be having a test over The Golden Goblet tomorrow because we did not have enough time to review for it today. We will continue reviewing tomorrow and the test will be on Thursday.

Math - We went over questions from Lesson 51. I taught the new concept from Lesson 52 and the students worked those problems not done on Friday. Everyone should have turned in lesson 52. There is no homework!

Seventh Grade

Spelling - Unit 19 is due on Friday. You do not have to do Vocabulary Connections this week.

Literature - Read Chapter 18 in Treasure Island on your own tonight.

Language Arts - We began discussing the research paper today. Everyone chose the animal they plan to research. You will need to go to the public library and check out at least two books on your animal. Tomorrow, we will go down to the library and look up the animals in encyclopedias. I also sent home a list of due dates for the paper. Keep these handy as they will tell you when your notecards, etc., are due.

Math - We went over the new concept from Lesson 51 today. This lesson will be turned in tomorrow. We then began going over the last test. Many students did poorly, so we are going through the tests and the students are writing down their mistakes. We will continue going over the mistakes tomorrow and there will be a makeup test on Thursday.

Eighth Grade

Lesson 50 - Scientific Notation. To write numbers in scientific notation, remember that you will ALWAYS have a number greater than 1 and less than 10 first. So, put the decimal point after the first non-zero digit in your number. Count how many places you moved the decimal to get there. That is the exponent you put on the 10. Here are four examples. The two examples on the left are large numbers, so you are moving the decimal point to the LEFT. The exponent is positive.
The two examples on the right are small numbers, so you are moving the decimal to the RIGHT. The exponent is negative.

When changing numbers from scientific notation to standard form, you are doing the above in reverse. If the exponent is postive, move the decimal point to the right. (If the exponent is positive, your standard number will be larger than what you started with.)
If the exponent is negative, move the decimal point to the left. (If the exponent is negative, your standard number will be smaller than what you started with...remember, if it has a negative exponent, then the number is less than 1.)


Algebra I - Lesson 50. You don't need help! Super easy.

See you tomorrow!
