Thursday, April 22nd

Sixth Grade

Lesson 95. Changing decimals to percents. Just move the decimal TWO places to the right!

Seventh Grade

Language Arts - Grammar worksheet over misplaced modifiers. Just follow the directions.

Spelling - Unit 32 is due tomorrow! Be sure you have completed the entire unit, including the challenge page, and have studied for the test!

Literature - We read another chapter in Tom Sawyer today. No homework.

Math - 7-11, continued. Today, do problems 10-13 and the Critical Thinking box. Remember, when you do a markup problem, you are still just dividing the difference by the original price. Now, the wholesale price is the original. Just subtract the wholesale price from the list price and divide that answer by the wholesale price. Remember to move the decimal two places to the right to make it a percent and round to the nearest percent. In the Critical Thinking box, remember to IGNORE the formula they give you. Just find the DIFFERENCE and divide it by the original price. Also, identify each of the problems as a discount or a markup. (If they price goes down, it's a discount...if it goes up, it's a markup.)

Eighth Grade

Algebra I did not have a new assignment today.

Pre-Algebra took the makeup test for Chapter 9. Also, there is a new assignment. #2-24 from Lesson 10-2.

For #2-9, you are just finding the length of each side of the polygons. Since they are all regular polygons, then each side is the same length. Just divide the perimeter by the number of sides.

For #11-24, you will be finding either the length, the width, or the perimeter of a rectangle. Remember that the formula for finding the perimeter of a rectangle is:

P = 2l + 2w

Perimeter equals twice the length plus twice the width. So, if you are given any of the parts of the above formula, you can just plug them in and solve!

Be sure to notice if the dimensions are different. If they are convert the LARGER dimension (meters are larger than centimeters) to the smaller dimension. Here is an example:

See you tomorrow!
