Module 1: Sequences and Series

 

Refresher

 

This is a play button that opens Percent (Food).

Use Math Continuum: Percent (Food) to review concepts relating to percentage. In the first topic you will review the definition of percent. In the second topic you will practise determining equivalent percents, fractions, and decimals. In the final topic, you will play a game that tests your knowledge of percents and your reflexes!

 

To get started, select “Percent (Food)” under the “Number” column. Then start with the first topic.


Next, look at the definition in Sequence. You may want to retrieve your copy of Module 1 Glossary Terms to update your definition of sequence.


This is a play button that opens Direct and Partial Variation: Arithmetic Sequences.

Review the basic properties of arithmetic sequences by revisiting Direct and Partial Variation: Arithmetic Sequences. This applet also reviews the relationship between arithmetic sequences and linear functions. Work through slides 1 to 11. Remember that any linear function with a y-intercept of zero exhibits direct variation, and any linear function with a non-zero y-intercept represents partial variation.


This is a play button that opens Order of Operations.

Use Order of Operations to remind yourself how to evaluate expressions that involve multiple mathematical operations. The applet includes three examples of varying difficulty.

Go back to the Are You Ready? questions and try them again. If you are still having difficulty, contact your teacher.
