Thank you this was very helpful.

Thank you! I have the kumon pre-algebra book for my son and was trying to see if I needed both kumon intro to geometry and geometry workbooks. So I'll buy both 👍 Edit: my son is a nearly a straight A student and his teachers always ask what we do at home (because he comes to school already knowing everything). I tell them for prek-6 I buy him 2 books every summer: brainquest prek- 6 workbooks, (depending what grade he's going into) and the "what you're (prek-6) grader needs to know" by the core knowledge series). His teachers know recomend those books to parents of kids who are behind and need to catch up.

Thanks for showing us the difference between the two Kumon geometry books. Was wondering what the difference was between the two.

Very informative! Thanks!

Try "Geometry revisited" by Coxeter, This book must be read by every math teacher.

thx

Put the link link of all these books

If only Spectrum had high school and college workbooks

Can/ do you also shoot from a kayak?

1) Euclid’s Elements. 2)Coxeter’s Inroduction to Geometry & Geometry Revisited. 3) I.F. Sharygin, Problems in Plane Geometry, or any of the Mir Publications on geometry. This is the way. The geometry of the schools is horrid. You have not seen geometry until you’ve studied something like this set of books. But really, Euclid must be read, in my opinion.
