Key to Fractions

Key To Fractions - Adding and Subtracting CoverKey to Fractions covers topics from basic concepts to mixed numbers. Handwritten examples provide a non-threatening model, and exercises are structured to ensure student success. With only one new concept per page, students aren’t discouraged by a mass of new, unfamiliar material.

Key to Fractions works well for elementary students learning new skills, and older students revisiting topics. Minimal reading is required, so students can easily work independently or in small groups.

We absolutely love Key to Fractions. I have been working with it since I started in special education over 8 years ago, and it has proven itself over and over again, especially with our more math-phobic students. —Karen Guerrero, The Almansor Center, South Pasadena, CA
