If you don't know who Shari Sloane is, then you must, must, must visit her site...http://kidscount1234.com/. I will be honest, I am biased toward anyone who SHARES not just ideas, but actual materials. I am a firm believer that teachers are made better by sharing, collecting, and tweaking.
Her website has so many things on it; math games, big books, literacy centers, and lots of pictures!
I adore her School is Cool CD. My kiddos love Like to Count It, Count It and Vowel Bat. I went ahead a forked over the $28.99 for the Vowel Bat set from Katie & Co. http://katieandcompany.net/puppets.html and it was well worth it. My students are simply mesmerized by that bat.
I also purchased the Like to Count it set for $18.95. We are thoroughly enjoying them!
Her newest CD came out last June, be sure to check it out!
