Tuesday, January 4th

Happy New Year! I hope everyone had a wonderful Christmas break and enjoyed the holidays. It was good to see everyone again as well as welcome a few new students to St. Charles.

Sixth Grade

Literature - We read from The Golden Goblet today, but there is no homework.

Spelling - Unit 16 is due tomorrow. Be sure you have finished the unit and studied for the test!

Math - Lesson 48. Dividing by a decimal number. When you divide by a decimal number (there is a decimal number on the OUTSIDE of the division box), then you first have to move the decimal point OVER. Move it the number of times it takes to make that a whole number. You might move it one place, two places, or more. THEN, move the decimal in the number inside the box the SAME number of places. It doesn't matter if the number inside the box becomes a whole number or not. You just need to move the decimal over as many times as you did for the number outside. Then, move the decimal up into the answer and divide like normal.

Here are a few examples:


Seventh Grade

Spelling - Unit 17 is due on Friday. You do not have to do the Vocabulary Connections pages this week! Remember, you can earn 10 extra points by having your parents sign the Home Study sheet you got today.

Literature - We read part of Chapter 12 today. Finish reading the chapter, but do not worry about answering any questions because I accidentally copied the answers instead! That's why some of you were so confused by the handout.

Vocabulary - Unit 7. We discussed the words today. Write sentences using 10 of the words. The unit and cards are due next Monday.

Math - Lesson 47. Powers of 10. Remember, powers of 10 are not MULTIPLES of 10 (10, 20, 30, 40...), but are when you multiply 10 by itself, like 10 x 10 = 100, 10 x 10 x 10 = 1,000 and so on. You can write powers of 10 with exponents. 10 to the power of 3 means 10 x 10 x 10. 10 to the power of 4, means 10 x 10 x 10 x 10 = 10,000. Also, you know how many zeros to put after the one because of the exponent. An exponent of 4, means to add 4 zeros.

Here are a few examples using powers of 10:



When you divide by powers of 10, you do the opposite - move the decimal to the LEFT the number of places as the exponent.

8th Grade

Pre-Algebra. Lesson 45. Volume.

Remember, the formula for Volume for rectangular prisms and cubs is just
length x width x height
The formula for volume of other right solids (unusual shapes), is:

Area of the base x height

Here are two examples:


Remember, when finding the area of the base, divide the shape into rectangles, squares, or triangles as needed. Then find the area of each of these shapes. Don't forget to divide by 2 when finding area of a triangle! Then, add the areas of the smaller shapes to find the area of the entire base. THEN, multiply that by the height given in the problem.

Algebra I - Lesson 45. Mean, Median, Mode, and Range. You do not need examples today!

See you tomorrow!
