Sixth Grade
Literature - There was a Selection Test today. No homework!
Spelling - Unit 23 is due next Tuesday.
Math - Lesson 63. Prime Factorization using Division by Primes or the Factor Tree. Remember that you are going to write the prime numbers that will multiply to give you the starting number. Here is an example of each:
Seventh GradeGrammar - pg 95-96. Exercise and DWS. Follow instructions for both!
Literature - None.
Research Paper - I began passing back the outlines and going over them with each student. I will finish doing this tomorrow. The rough draft is due on Thursday, February 24th.
Math - Lesson 63. Symbols of Inclusion. Remember, you have to wait to multiply numbers that are stuck to parentheses before adding or subtracting to any numbers before that. For example:
12+3(10-8)
First subtract 10-8 and get 2. Then multiply 2 by 3 to get 6. THEN add 12 to 6 to get 18. Don't make the mistake of adding 12 and 3 first since the three is "stuck" to the parenthesis.
Eighth Grade
Pre-Algebra - Lesson 63. Practice and evens only. the first example is as follows:
Prince Charming traveled 60 leagues in 2 days. Then he doubled his rate. How long would it take him to go 300 leagues at this new speed?
First, find out what his speed is before he doubled it. The rate is in the first sentence, "60 leagues in 2 days". Write that as a rate and reduce it to # of leagues in 1 day. Then you will double that amount. Remember, you are doubling how many leagues he does in 1 day...don't double the days too! That won't help. See below:
The second example is much like the first except the rate is tripled. First you would find the rate statement and write the rate.
The machine could cap 500 bottles in 2 hours. If the rate of the machine were tripled, how many bottles could be capped in 10 hours at the new rate?
500 bottles in 2 hours is the rate - this would reduce to 250 bottles in 1 hour. To triple how fast the machine was going, you would multiply 250 x 3 = 750 bottles in 1 hour. Remember, don't multiply the time by 3 too! That'll give you the same rate that you started with. You want to increase the number of bottles in one hour. Then, you use the rate of 750 bottles in 1 hour to find the number of bottles capped in 10 hours.
For the third example, you are given two rates and asked by how much it increased from the first rate to the second rate.
Raul ran 6 miles in 2 hours. Then he ran 20 miles in 4 hours. By how much did his rate increase?
So...write both rates as miles per hour. 6 miles in 2 hours would reduce to 3 miles per hour. 20 miles in 4 hours would reduce to 5 miles per hour. So, the rate increased by 2 miles per hour.
Algebra I
Lesson 63 - practice and evens only.
To simplify square roots, you will not use a calculator. First, write the number under the square root sign as a product of prime factors (do the factor tree!). Then, for every pair of numbers that is the same, one goes outside the square root sign. For any singles, they have to stay inside. (Shelby says they were bad because they aren't perfect squares!) Here are some examples:
See you tomorrow!
