Week of October 19-23, 2015

Honors Math:

Thank you for all the hard work you put into my class and how great you are every single day! I love being your teacher!

This week we will continue to work on adding integers with the same/different signs. Remember our adding integers song! :)

We will also begin subtracting/  multiplying/ dividing integers. Remember these are your foundation rules into the algebra world I told you about. Keep on practicing every day and I promise everything will run smoothly! Remember to know your multiplication tables by heart too!

Our District Benchmark #1 is around the corner so make sure to stay alert in class so that you don't miss out.

Example:

Problem:	The highest elevation in North America is Mt. McKinley, which is 20,320 feet above sea level. The lowest elevation is Death Valley, which is 282 feet below sea level. What is the difference between these two elevations?
Solution:	When solving problems with large integers, it is not always practical to rely on the number line. Using integer arithmetic this problem becomes: +20,320 - -282 = ?
	We need a rule for subtracting integers in order to solve this problem.
	Rule:   To subtract an integer, add its opposite.
	The opposite of -282 is +282, so we get: +20,320 - -282 = +20,320 + +282 = +20,602

In the above problem, we added the opposite of the second integer and subtraction was transformed into addition. Let's look at some simpler examples of subtracting integers.

Geometric Construction:

You guys have been doing great with the STEM projects. I am very proud of you for building pre-engineering skills. This week we will begin working with art geometric tessellations!
