6th Grade

Lesson 5 - Order of Operations. Remember, you must first work any part of a problem that is in parenthesis first, then work the rest from left to right. If there are no parenthesis, just work the problem from left to right. If you have a fraction bar with problems on top and bottom of it, do those first, then divide the top number by the bottom number. The lesson is due tomorrow!


7th Grade

Spelling - Unit 1, Vocabulary Connections pages.

Grammar - DWS on pg. 274 and Exercise A on pg. 275. Follow the directions exactly on both!

Vocabulary - Remember, cards are due on Monday and the unit is due Tuesday!

Math - Today in math, we began exploring the rules of adding integers. We used algebra tiles to discover how to add a positive number to a negative number. Everyone really caught on! There is no homework tonight.

Literature - We began reading a story, "The Third Wish" today. We will finish it tomorrow. No homework!

8th Grade

Lesson 1-3. Greatest Common Factor. Remember, to find the GCF of two numbers, first write the prime factorization of the two numbers and write what the two have in common. For example, to find the GCF of 60 and 84, you would use a factor tree to get 2x2x3x5 for 60 and 2x2x3x7 for 84. You can see that both of these have the numbers 2x2x3 in them. 2x2x3=12 so the GCF of 60 and 84 is 12. To simplify fractions, divide the numerator and the denominator by the GCF. If you don't know it, just divide by what you can tell goes into both numbers, but remember you may have divide more than once. To write a decimal as a fraction in lowest form, first SAY the decimal number (properly) and then write that as the fraction you hear. So 1.5 is not "one point five". You would say "one and five tenths" which is easy to write as a fraction. Then just reduce the fraction to simplest form! Lastly, you have four problems that I wrote on the board (Kendall, I will give these to you tomorrow - or when you come back) that have variables in them. Remember, the GCF is what the two expressions have in common. So if one expression is 3x squared (the x has 2 as an exponent) and 6x to the third (the x has 3 as an exponent) then what the have in common is 3x squared. 3 goes into both 3 and 6 and both expressions have two x's. I can't do exponents in typing! Sorry. (I know...it's a pain) The assignment is #2-30 evens, #38-56 evens and the four problems from the board.

See you tomorrow!
