I suggest getting the Rainbow Resources catalogue to look through, it lists or reviews most of the homeschool curriculum for sale (including singapore math- we get it cheaper from them then the Singapore website). Also try the Michael Olaf website to see their Montessori Materials for home/classroom, very good ideas, their paper catalog has quite a bit besides the usual lists of materials for sale.
Discovery Toys have some neat games that use math concepts also. Their cd rom game Dollarville is really great to teach money concepts. This is a great time of year to ask for games for presents, deck of card games like UNO, etc.. Legos, Connect Four, yahtzee come to mind right away. Somewhere
there is a website called Pig Out on Math that has lots of neat dice games- stuff I have not seen elsewhere.
Mel, if you want to just make up some mazes, simple math worksheets - not buy anything - pm me and I will post a list of links that you generate your own worksheets for math & print out as needed.
