Ds#1 just started book #3 of 6 for MEP Year 3, and it began with Geometry. The picture is the student page, which he hasn't even done yet because we've been having so much fun discussing and exploring the exercises presented in the Lesson Plans.
This, of course, led to us talking about Zomes. We actually haven't build with them in awhile, so now that we are on break this week I decided to build the Hyperdo Model with them. You can read all about Zomes, see the models, and even get some discount codes from AtHomeScience: Hyperdo Kit from Zome.
Our homeschool co-op bought Zome kits when we first started. Mostly they have been used by the 6 to 8 year olds to just build whatever they wished. Ds#1, after the geometry lesson, asked if we could have a Zome co-op class where we learn more about geometry. I told him I thought it was a great idea, though I silently considered how many other kids would be excited about a geometry class. I'll offer it for the fall and see. It was a heart-warming homeschool moment.
