I love to use this alligator “snapper” (from Safari Ltd.) to teach greater than and less than! Jack Hartmann has a song – Mr. Alligator Can Chomp on his CD – Movin’ 2 Math. Here are the lyrics:
Mr. Alligator can chomp, he can swim and he can stomp, he’s a real smart alligator…he chomps at numbers that are greater!
Once we get a couple of numbers up, Mr. Alligator looks them over and then decides which one he will “chomp”! The kids make alligator mouths with their hands open in the direction that they think Mr. Alligator should chomp. It’s a lot of fun!
