Beyond Base Ten (William & Mary Units)

Excellent product; delivered on time and as described. I wouldn't suggest this for 3-5 grade though; I think 6-8 would do better with this unit. Also, be prepared for parents being VERY upset that they're seeing assignments and/or homework they don't know how to do. Some of the lessons in here require multi-step operations, so best done with a class mature enough to handle taking a few notes.

I just completed this unit with gifted fifth grade math students. They really rose to the challenge it provides and gained a deeper understanding of place value and non-place value number systems. It is a great differentiation unit to use during instruction on number sense.

Great book!!!
