Below you will find tools (blog, class presentations, videos, websites) to enhance your understanding of Chapter 6 concepts. The SMARTBoard lessons that are presented in class are here in PDF format. Please keep in mind that these files will not be interactive like the class presentations due to the PDF format.

This PowerPoint presentation reviews information discussed in class with additional practice problems. Answers are included for you to check your work!

The videos listed below can all be found on your Educanon Account. Remember that these videos are interactive and involve questions that help you review important concepts.

*Lesson 6-4: Converting Customary Units Using Proportions (About 4 minutes)

Use this resources during the entire Ratios and Proportions unit of study. There are several videos on each topic throughout the chapter. This link takes you to the Virtual Nerd website. Once there, click on "Grade 7" then "Ratios and Proportional Relationships". All of the videos in this section can be watched throughout the unit!

This website has a lot of information and games that you can play to increase your understanding of ratios, rates, and percent of change. I suggest checking out the "Ratios" page of information and the "Unit Price Game".

This is a Khan Academy site and provides several examples of 7th grade ratios, rates, and proportional relationships. Many of the examples include fractions, which can be challenging. There are example problems and videos. You can click on your topic of interest!

This website reviews using "King Henry" to complete metric system conversions.

This link takes you to the Virtual Nerd site. Once there, click on "Ratios, Proportions, and Percent" then "Proportions". The first 3 videos will review information discussed in class.

This link takes you to the Virtual Nerd site. Once there, click on "Ratios, Proportions, and Percent" then "Scale Drawings and Models". There are 4 videos in this section.
