I like Zaccaro's Primary Grade Challenge Math. I also like Venn Perplexors and math material from The Critical Thinking Co.

I second the suggestion regarding Penrose the Mathematical Cat. We started reading it last week and it seems like a great fit for DS5 right now.



It makes me wonder if it would work for my mathy DS5. He works on 4th grade level, but I think Descartes' Cove is 6-8th grade. Let me know how it goes. If your son stays with it for a few months I may consider it too.

I stumbled across the BBC's website when another poster mentioned one of the adventure games you can play

DS5 loves the reading/math games listed in the KS1 area

I was a bit surprised by the difficulty of some of the time/clock based games. But you know what, it was good because DS really had to think to answer.

I've been considering Descartes' Cove for my almost-7yo, too. He's doing geometry and loving it right now--we did parallel lines cut by a transversal yesterday, and he got a big kick out of seeing all the congruent and supplementary angles in the "puzzle." Then I read this thread and it made me think that the DC game might be right for him after all...

So please keep us updated on how your DS likes it as the newness wears off, would you, Cathy? Thanks!

I just found this page on Hoagies today:

Lots of ideas for puzzles!!!

We also found this during the weekend when I was trying to find cut outs of geometric shapes:

DS gets limited computer time each day. When he's not making "booklets" of Wikipedia printouts he likes playing educational games like these. I think I liked the BBC games better, but there are a few pattern types of games here on PBSKids.

BTW, if anyone has a link to 3D shapes that can be cut out, please post. That is what I was looking for originally. Something like this http://pbskids.org/cyberchase/games/23dgeometry/index.html but with more shapes.

Search for "nets". I found this: http://www.mathsisfun.com/platonic_solids.html

I've never actually downloaded the software itself, but you can figure some of them out just by looking at the photos.

Found another! Just paper models to print out on this one -- no downloading
