Students are given 6 specific blocks: two yellow 2x2, one yellow 1x2, one yellow 2x4, and two flat red 2x3s. With these basic pieces, students are asked to make their own version of a duck. The point is for students to then be able to compare and contrast what they have created. They are able to see all the possibilities and creativity of their classmates. This can even be used as a math lesson on graphing. I put the bricks into square snack sized bags to make them easier to pass out. For storage, I was lucky enough to find this LEGO suitcase in the clearance department at WalMart. It even had a fireman set in it as a bonus.
