Dr. Ruth Beechick spent a lifetime teaching and studying how people learn. She taught in Washington state, Alaska, Arizona and in several colleges and seminaries in other states. She also spent thirteen years at a publishing company writing curriculum for churches. In "retirement" she wrote for the homeschool movement. Her degrees are A.B. from Seattle Pacific University, M.A.Ed. and Ed.D. from Arizona State University.
Good primer on K-3 math instruction. Mostly not new to me, but helpful if you're just starting math instruction: avoid testing if possible (although you can test to find gaps or build confidence), definitely don't teach to a test, embrace the advantages instead of trying to make homeschooling like institutional schooling, use real life to teach math: games, kitchen, shopping trips, etc.
New to me was the three modes of math thinking:
1. Manipulative - Physical manipulation, like counting fingers or blocks - Only mode until age 6 or 7 - Greatest source of math anxiety is an underdeveloped ability at doing manipulative math
2. Mental Image - Mental manipulation, like counting blocks in your head - Develops as child uses physical manipulatives - Eventually it will be too slow to count on their fingers, and they will realize they can do it faster in their head
3. Abstract - Abstract manipulation, like 2 + 2 without picturing "2" of anything - Piaget says abstract thinking doesn't develop until age 12 - Delay teaching symbols until child is ready
I've read that claim that children don't develop abstract thinking until 12. Obviously a younger child can solve 2 + 2, but maybe they're doing mental manipulation or memorizing without understanding? But children do all sorts of abstract thinking before 12, like reading or using a calendar or a telling time on a clock. Is that kind of abstract thinking somehow different than abstract math?
This is more a pamphlet than a book, but highly useful for anyone planning math curriculum for the K-3 range, especially if they want to avoid instilling the student with “math anxiety.”
