Periods 1/2 and 3/4 - We have started our new unit on integers and rational numbers. Last week we learned about zero pairs and how to graph them on the number line. Zero pairs are additive inverses (opposites) that when added together will have a sum of zero.
Examples:
-9 +9 = 0 5 + (-5) = 0 11 + (-11) = 0
This week we will be learning how to use the number to model addition of integers. The main concept to remember is that positive numbers mean to count up which represents moving to the right on the number line and negative numbers mean to count down which represents moving to the left on the number line. We will also apply this to real world situation such as withdrawing or depositing money into a bank account, golf scores, football plays, temperature and elevation.
Period 8 - Last week we finished up our notes on exponent properties and Friday we took our quiz. This week we will learn how to write numbers in scientific notation and how to convert from scientific notation form to standard form. There will be a project presented to the kids towards the end of the week that will be due next week. Next week we will begin to learn how to add, subtract, multiply and divide numbers when written in scientific notation form.
Period 9 - Students are continuing to work on scientific notation skills along with exponent properties and decimal operations.
