GCF LearnFree: Basic Math

Details

Activity Description

GCF LearnFree provides help with basic math in the areas of subtraction, multiplication, division, fractions, decimals, and percents. With an emphasis on images and interactives, their math tutorials make learning math easier. The tutorials are designed to be like a math workbook, so learners can practice what they learn directly within the lessons and learn at their own pace.

Preparation

1. Preview the site to get comforatble with how it works so you can explain it to your students if there are questions.
2. Decide which topic to focus on.
3. Find the page in your class textbook which deals with the same topic.
4. Post the page(s) on the board.

Teacher Tips

• On the second day, provide five review problems to see if they understood yesterday's lesson.

More Ways

• Go through each of the sections: addition and subtraction, multiplication and division, fractions, decimals, and percents
• The GCF LearnFree site has so many resources that it's hard to know where to start. Go out to the home page and browse around, especially in the Everyday Life, Reading, Work and Career, and Technology sections.
