To teach comparing sets of numbers and Indians simultaneously, each pair of kids got an Indian workmat, number cards to 10 (or dice), and their own cup of popcorn kernels. (Yes, being kindergarten there was a lecture about not eating them or putting them where they don't belong.) They each rolled a number and counted out their corn, then used the velcro greater-than/less-than/equal-to cards to determine who had the greater amount. For kids that found this a breeze, it turned into a game: the person with the greater amount got to keep the kernels, and play continued until one player no longer had enough kernels to play.
