The Witch's Cauldron is a fun math center where students pull cute Halloween number cards out of a cauldron and try to find that number their 100 Chart. Once they locate the number, they color in that square. The students must find every number before their challenge is done. Students familiarize themselves with the patterns of numbers; this will aid them as they learn to count forwards and backwards to 100 this year! Save the cauldron for my Pot o' Gold center for St. Patrick's Day!.
