Circle Math is our unique way to teach subtraction and regrouping. It is the process of breaking up a large problem into many small problems, solving each small problem, and adding the results.
Subjects covered: Assessment and Assessment Guide, Regrouping: Introduction and Philosophy, Review of Circle Math (expanded notation), Discovering how to Regroup with Subtraction using manipulatives and Nonstandard Regrouping, Standard Regrouping,Three Digit Regrouping: Manipulative and Recording
A constructivist approach in which students learn through hands-on exploration, discovery, inventions, and the creation of models.
The Parent/Teacher Guide has instructions on how to teach the lessons, sample dialogues, games, and the Answer Key. The Student Workbook has worksheets and practice pages. We highly recommended that you order both for a complete package.
