Sixth Grade
Lesson 31 - Area of a rectangle. Remember, to find the area you just multiply length times width! The answer will be in whatever the measurement is SQUARED. So if it is cm, write sq. cm.
Seventh Grade
Today, the class took the pretest for Spelling. Do the first two pages tonight. In Vocabulary, we discussed the words for Unit 5 and for homework, write 10 sentences using 10 of the words.
I want to thank Mrs. Brandon for volunteering and staying with the class while I attended the funeral of Mr. Sine's dad. I appreciate it so much! And thank you, class, for being so good while I was gone. I know you enjoyed the movie!

Lesson 2-7 #2-34 ALL and #37-42 ALL.
For the first section, remember the real numbers diagram I drew on the board (and that you should have in your notes!).
On the Rational Number side, remember Natural numbers are just the counting numbers - starting at 1, so 1, 2, 3, 4, etc. Whole numbers are ALL the natural numbers PLUS the number zero. Integers are ALL the whole numbers and also their OPPOSITES. For fractions and decimals that terminate or repeat, they are just rational, but don't fit inside any of the other ovals on the right side of the diagram. Make sure you are writing ALL the possibilities for the first section, not just one possibility.
For ordering from least to greatest, it would be helpful to write the numbers rounded to the nearest hundredth. You can look up any of the square roots in your table at the back of your book, or just use a calculator. Then order them. Just be sure to write the order using the original numbers given.
For finding the distance between two numbers, you are just finding the difference. So, subtract the two numbers. It doesn't matter which one is first, so long as you are subtracting. You will not be using a negative sign on any of these because to find the DISTANCE between two numbers, it is always positive. It's like asking, "How far apart are these two numbers on the number line?" They can't be a negative number apart. If the number is irrational, just round it to the nearest hundredth before subtracting. For fractions, you can use a common denominator and subtract. If one number is positive and the other number is negative, you actually end up ADDING the numbers to find the distance. Again, think about how far apart they'd be on the number line. That will help.
To find the midpoint between two numbers, you are finding the AVERAGE of the two numbers. This will give you the number that is exactly in the middle. To find the average, add the two numbers and divide by TWO. If you have one fraction and one decimal, change the fraction to a decimal first, then add and divide by two. If there are two fractions, just use common denominator, add and divide by two. (remembering when you divide in fractions, you multiply by the reciprocal - in this case, the reciprocal would be 1/2.)
For the Critical Thinking questions, use the diagram above or what you drew in class. THINK about the question! Remember, not all integers are whole numbers because the integer oval is not entirely inside the whole number oval.
See you tomorrow!
