This project was made for my recent gallery of educational projects for KIDS - http://scratch.mit.edu/galleries/view/183099 It is based on some of the problems that I've created in the past for the contests in my classes, and now I've added a few new ones. It is also a remix of ffred's project shared in the Portuguese Scratch site: http://kids.sapo.pt/scratch/projects/ffred/1250 A lot of thanks to ffred by the help in the translation to English.
