SIXTH GRADE

Today, the class took another timed test. This one was 100 multiplication facts. Some students will need to get a bit faster! The homework is to finish the front side of the assignment from yesterday. You still don't have to do the back side with the word problems.

SEVENTH GRADE

Math: Today's assignment is to do Column D on Lesson 1.4 and columns D & E on 1.5. Then, do the word problem page that is numbered as homework #3.

Geography: We spent some time talking about the different kinds of maps today. There is no homework!

EIGHTH GRADE

Pre-Algebra: The assignment is homework #4. All operations with fractions. Please send me an email if you are having trouble. I'd be happy to help!

Algebra I: I tested out my new iPad app that makes videos today and it worked great! I explain how to put the numbers on a number line in this one...which includes how to find which two numbers a square root is between. Here is that video and then below, I explain how to do absolute value.

 


For absolute value, remember that absolute value means how far away a number is from zero on the number line. This goes only for whatever number is between the absolute value lines. So, here are a few examples:

 For a), you see that the -2 is between the absolute value lines, so the absolute value of -2 is 2. 
For b), you see that the 5 is between the absolute value lines, so the absolute value of 5 is 5. (Remember, it's how far away the number is from zero on the number line....absolute value doesn't mean "the opposite" of a number.)
For c), you see that the -4 is between the absolute value lines...so the absolute value of -4 is 4, but there is a negative sign in front of the absolute value, so your answer to c) is negative 4. That first negative doesn't go away.

Also, you will have one or two where you have to add or subtract BEFORE you find the absolute value. So if you have -2 - 5 between the lines, you would first find the answer as -7. Then you would find the absolute value of that, which would be 7.

Email me if you are stuck! I'm happy to help. Always. 

See you tomorrow!
