The Parent/Teacher Guide has complete instructions on how to teach this math program. The Student Workbook has worksheets and practice pages. Both are needed for a complete program.
This unique approach to subtraction was developed by Prof. Emeritus Michael Butler at the world renowned UCI Farm Elementary School.
- Memorizing the recipe for how to borrow does not result in understanding of the basic concepts of regrouping. The Patterns in Arithmetic series teaches for understanding. The student constructs understanding through experience not being told "how to do" the problems.
- The student is guided to find patterns and generalize those patterns in to working knowledge of how procedures work and why they work that way.
- Circle Math is our unique way to teach beginning subtraction and regrouping.
- Parents are guided though a series of lessons that give sample dialogues that a teacher might have with a student who is learning.
