Thursday, October 28th

Sixth Grade

Math - Lesson 30. Due Monday. Least Common Multiple and Reciprocals. Remember, for LCM, you are going to list several numbers that the two numbers GO INTO. (You cannot list all of them because the lists would never end.) So, to find the LCM of 3 and 5, first list the multiples of each number.

Multiples of 3 are 3, 6, 9, 12, 15, 18...

Multiples of 5 are 5, 10, 15, 20, 25....

Since 15 is the smallest number that is on BOTH lists, 15 is the least common multiple of 3 and 5.

Remember, multiples are what you get when you COUNT by a number.

For reciprocal, remember that anytime you multiply a number by its reciprocal you will get 1. A way to remember how to find the reciprocal is flip it over if it's a fraction. If it is a whole number, write the whole number over 1 and THEN flip it over. So, the reciprocal of 5 would be 1/5 because 5 is the same as 5/1, so flipping it would make it 1/5. The reciprocal of 2/3 is 3/2.

Literature - Look up the definitions of the vocabulary words for Section 2 Set 1. We will go over these on Monday.

Spelling - Unit 10. This will be due on Wednesday this time! I will make sure you get your books tomorrow.

Seventh Grade

Vocabulary - Test over Unit 4 is tomorrow! Please study the words.

Literature - We read from "The Monsters Are Due on Maple Street" today and will finish it tomorrow and watch the Twilight Zone episode.

Spelling - Unit 10 is due tomorrow. Also, study for the test!

Math - Lesson 26. Due tomorrow! Multiplying and Dividing mixed numbers. Remember to follow these steps:

1. Change whole numbers and mixed numbers to improper fractions. For whole numbers, just write it over 1. For mixed numbers do the U-TURN.

1a. If it is division, change the division sign to multiplication and flip the second fraction. If it is multiplication, skip this step!

2. Cross cancel where you can. Remember you cannot cross cancel side to side. Only top numbers with bottom numbers.

3. Multiply across and simplify if the answer is an improper fraction.

That's it!

Eighth Grade

Pre-Algebra - Graph worksheets.

Algebra I - Lesson 29. I will do a video for you this weekend! Check back for live examples on how to do these problems. The assignment isn't due until Monday as we will not have math class tomorrow.

See you then!
