Sixth Grade
Math - Lesson 1. Everyone did a great job today and remembered how to do the problems in lesson 1, so I won't put examples up. If you do have a question, go ahead and email me! Seventh Grade
Literature - We began going over questions from Hatchet today. Mr. Gungoll came in for a short visit and everyone was so well behaved! I was very proud of you. There is no homework.
We also learned the first idiom today! It was a day in the sun. The students each wrote a sentence using the idiom. They will learn a new one each day.
Math - Lesson 1. Remember that counting or natural numbers start at 1 and count up and we show those numbers like this - {1, 2, 3...} Then, whole numbers include zero so we show them like this - {0, 1, 2, 3...} The only difference between counting numbers and whole numbers is that whole numbers also includes zero! That's it. To evaluate expressions, remember that you are just "plugging in" the values given for the variables and solving the expression. A variable is one of the letters that stands for a number. Here is an example:
Evaluate the following expressions when: a=4 and b=12
a + b b-a ab b divided by a
Plug in the numbers for the letters and solve:
4 + 12 12-4 4 x 12 12 divided by 4
16 8 48 3
Be sure to use your MiniMath booklets if you are confused!
Eighth Grade
Pre-Algebra - Lesson 1. There are several concepts in this lesson. First, to name the value of a certain digit in a number, just use the table on page 1. Count over how many places the digit is from the right and name that place. Second, if you are asked the following: Write the 7 digit number that has a 4 in the tens place, a 2 in the ten-thousands place, and 5's in all the rest of the places, write 7 5's, like this: 5555555Then put the commas in by counting by threes from the right.5,555,555Then change the numbers that are exceptions. Change the tens place to 4 and the ten-thousands place to 2.5,525,545For the problems that ask you to write the numbers in words, first put the commas in the correct places. Then, say the number out loud. Be sure you are saying the proper places. If you can say it, you can write it! So, the number from the above example is now:five million, five hundred twenty-five thousand, five hundred forty five. If you are supposed to write a number with numerals from words, be sure you aren't skipping anything. For example, to write this number, twenty-two billion, forty-one thousand, three, you would do this: 22,000,041,003I put three zeroes after the 22 because there are no millions. There are also no hundred thousands so I put another zero. Then there are no hundreds or tens, so I put two more zeroes. Be sure you are using place holder zeroes! If you are unsure about one, email me! For expanded notation, remember each non-zero digit will be in a separate parenthesis. So, if you n7eeded to write 41,025,700 in expanded notation, you would do the following: (4x10,000,000) + (1 x 1,000,000) + (2 x 10,000) + (5 x 1,000) + (7 x 100). Each digit is multiplied by it's place value. Since the 4 is in the ten-million's place, it is multiplied by ten million, etc. You don't have to show the zeroes in expanded notation.To write a standard number from expanded notation, remember to include zeroes for places not stated. Here is an example: (7 x 100,000) + (3 x 1,000) + (2 x 100) + (4 x 1) This would be: 703,204There is no number multiplied by ten thousand or ten so there are zeroes in those places.Again, PLEASE email me if you are stuck and need help. I want you to really utilize both the blog AND me each night! I'm here for you and don't want you struggling with math!Algebra I. Your assignment is Lesson 1, but it was so easy, you don't need examples! (If you really do though, just email me.)I was very proud of how hard all of eighth grade worked today. You also were very respectful of each other. Thank you!See you tomorrow....Mrs. Swickey
