This is an activity for small groups or an entire classroom that is Halloween themed. It focuses on teaching the concepts of MORE and LESS. The teacher indicates how many markers to put next to each Halloween character by spinning the spinner that is included in the packet, or by rolling a die. The students place the corresponding number of markers on their mats, and use their visual to describe which character has more or less markers. This is a great activity for initially teaching these concepts because the students have a concrete visual. Their motivation increases significantly if you turn it into a "Trick-or-Treat" activity and hand out candy for correct answers!
