Monday, March 29th

Sixth Grade

Today, the class took a test. There is no homework! Tomorrow, we will begin on Lesson 86.

Seventh Grade

Grammar - We started Chapter 13 today - Formal and Informal language. Follow the directions for exercises A & B.

Literature - We read Chapter 5 of Tom Sawyer today. Tomorrow, there is a short quiz over Chapters 1-4 and the vocabulary words from Chapters 1-4.

Spelling - Unit 29. You will not have to do Vocabulary Connections this week. Finish the first two pages of the unit.

Math - Lesson 7-2. Changing fractions and decimals to percents. To change a decimal to a percent, move the decimal point two places to the left. To change a fraction to a percent, you can do a couple of things: 1. Make an equivalent fraction with a denominator of 100. The top number will be your percent. 2. Multiply the fraction by 100 over 1. Change the answer into a mixed number by dividing the bottom into the top and writing the remainder as a fraction.

To change a percent to a fraction. write the percent over 100 and reduce. For percents that are written as decimals, you can divide by 100 and change the decimal into a fraction and reduce. For percents that have fractions, change into improper fractions and divide by 100 (or multiply by 1 over 100) and reduce.

#2-24.

Eighth Grade

Pre-Algebra - Practice Test over chapter 8. There will be a test tomorrow! Be sure to go over each lesson in Chapter 8. You will NOT be able to use calculators on the whole test.

Algebra I - Distance Problems. There were a few problems that would give you a different equation for the times. Here is an example problem:

John took a drive to town at an average rate of 40 mph. In the evening, he drove back at 30 mph. If he spent a total of 7 hours traveling, what is the distance traveled by John?

First, we will decide to use T for the subscript for going to town and H for the subscript of driving back (assuming it means home). Then, set up the equations like this:



Then, you will substitute the two rates and the time statement into the equation like this:
I hope this helps! Just send me an email if you any questions.

See you tomorrow!
