I've gone to her workshops the last 3 years and I've spent WAY too much money on her stuff.
From my experience teaching both 3rd and 4th grade, the resources I've used the most are:
--place value dice (I use them nearly daily)
--double decahedron dice (also use nearly daily)
--Math Drills that Thrill resource book (we use the random number CD that comes with this every single week!)
--the faster random number CD that you have to buy separately
I also use the Ron Brown Math CD (Math Concepts I & II) all the time!
I've been digesting her ideas for the last 3 years and I'm STILL overwhelmed!!
