Lesson 30 - Least Common Multiples and Reciprocals. Remember, a multiple is when you take the number and multiply. For example, the multiples of 20 are 20, 40, 60, 80, etc. So, to find the least common multiple of two numbers, you would need to think about the first number that they both GO INTO. So, if you wanted to do the LCM of 20 and 15, you would also need to list the multiples of 15 until you found a number that was also on the 20 list. 15 - 15, 30, 45, 60....Since 60 is the first number on both lists, it is the LCM.
For reciprocals, remember, all you have to do is just flip the number over. That's it! So, the reciprocal of the fraction 2/3 is just 3/2. The reciprocal of the whole number 5 is just 1/5. (think that you write 5 as a fraction as 5/1, then do the reciprocal). If it is asking you to find what would multiply by a number to equal 1, you are just finding the reciprocal. If it is asking how many of a fraction is in 1, again, you are just finding the reciprocal.

Spelling Unit 9 - 2nd two pages. You will NOT have the Vocabulary Connections pages this week since it is a short week. The test is Thursday!
Vocabulary Unit 4 - The unit is now due tomorrow because "someone" wrote that on the board and confused some people!
Literature - Questions for the story, "The Luckiest Time of All". They are: TAS, #1-5, CT&R #1-4, and AL #1-2.
Math - Lesson 2-9, #2-24 All. To solve the problems with formulas, be sure to write down the formula you are supposed to use first EVERY TIME! Then, you will plug in the values you are given and solve the equation. You may have to solve it using two-steps, like what we've done the past few days, or you may just have to multiply. Here are a few examples:
In the above example, you plug in the 40 for the V, the 5 for the l, and the 4 for the h. Then, you multiply the 5 and the 4 to make 20w. Divide both sides by 20 to get the answer.
In this problem, you are asked to find the length. (The L looks kind of like the number one, but just know that's an L. You should write it in cursive to really be able to tell.)You plug in the values you know. So, for the P, you put 70 and for the w, you put 10. Since 2w means 2 times w, you multiply 2 times 10. Then, you have a two-step equation. Eliminate the constant term first - subtract 20 from both sides. Then, you divide by 2 on both sides to solve. Don't forget to write the answer with dimensions!
Eighth Grade
Today, the class began working on the Practice Test for chapter 2. We aren't finished with chapter 2, but I am going to give a test over the material from Lessons 2-1 through 2-6. The problems on the practice test are: #1-19, 40-43, and #48.
See you tomorrow!
