Unit 4 Percent Problem Solving

I hope everyone enjoyed their holiday break and were able to relax a little bit!

When we get back we will begin our Unit on Percent (Unit 4).


I have already begun to gather some resources for you.  If you want  a head start you can start reviewing the concepts we will be covering in class.

I have also assigned new videos on Learn Zillion to help you during the percent unit.  You should be watching these videos!

There is a new TenMarks assignment posted that is all percent questions.  You do not have to complete the assignment but it is there for you to get some extra practice throughout the unit.

Percent is my favorite so hopefully you will enjoy this unit as much as I will!

Decimal Operations

As we begin exploring problem solving with decimals I want you to keep in mind HOW TO problem solve.  The chart below will still come in handy.


I will continuously update this post with additional resources to help you with decimal operations so please keep checking back!!!  Screencasts coming soon!!

Check out the links below:

Khan Academy Word Problem

NOTE: When you multiply decimals, the product will have a combined total of decimal places from the numbers you are multiplying. (example shown below)

Dividing Decimals : The Basics

Dividing Decimals PowerPoint

When problem solving with decimals (and any form of numbers) it is VERY important that you make sense of the problem.  Previously you may have been taught to look for specific key words in order to determine which operation to use.  You have seen this year that that method doesn't always work out because some "key words" can be used for more than one operation.

Don't panic...

just make sense of the problem!
