Lovemydd, I followed your link to this post from "homeschooling kinder" thread, and I'm inspired by your wonderful homeschool set-up. My DS is about to turn 4, so I'm starting to think maybe I should provide more school-like activities for DS to explore.

My DS already taught himself how to multiply by observing our sand timers (one 5 min & one 10 min), so before I invest in materials, I want to ensure I'm meeting him at his level. The trouble is determining that level - he is not one to answer direct questions about what he knows, so mostly I find out by observing him or through him telling me during play. I love the Montessori materials, but I wanted to ask for your review of the math manipulatives you purchased and how their "shelf-life" has fared with these remarkably fast learners.

Also, I didn't see pics posted that you mentioned. Could you please pm me with those? Thanks!!
