This is a collection of 11 different challenges in which your students take an "oblique" view of a building and then snap it together using Unifix or Snap cubes. After the building has been assembled, students create blueprints of the top, front and side view.
My diatribe: in an age where everyone spends entirely too much time in front of screens, shouldn't we also have the opportunity to work with our eyes and hands on visual puzzles? Yes, I'm talking about genuine "hands on" tasks that involve spacial thinking in 2 and 3 dimensions. (Oh, and "swiping" and "pinching" is not "hands on," I hope you agree.)
Anyway, I think you're kids will really like them: print them up, put them near a tray filled with cubes and watch them go at it. In the beginning, it will be difficult, because they may not have done a task like this before, but they will come to enjoy and appreciate it.
If your kids really like this activity, I invite you to have them make their own models, which I will turn into puzzles for you. Just take photos of them and send them over to me!
If you like this activity, then you should definitely look at my other activity, "Can You Build This," in which the blueprints are provided and the students have to construct the models that go with them. You can see it here:
