This machine is a complement to the Fry 1,000 Word Cards in my store. The word cards are separated into Sets A-T. The gumball machine includes gumballs for each of those sets. As a students masters a set of sight words, he/she gets to color in that corresponding gumball. It serves as a visual motivator. The kids love to see their gumball machines filling!
(I color in the blank gumballs before displaying the machines. So, at first glance, all students have gumballs in their machines.)
