The buses did require some work by cutting two different sheets and some glue, but they are so cute that it was worth the effort!
I have a list of all the other shapes I have on cartridges that I think they would like...before long I will get to cut some... pumpkins, leaves, snowmen, gingerbread men, butterflies, seahorses, dragonflies, hearts, stars, dogs, cats, etc! The possibilities are endless! I'm introducing this incentive to them tomorrow so I'll let you know how it goes! =)
