I love bringing new puzzles to class. I focus on the most approprate strategy e.g. ‘constant manipulation’ is probably going to work best for you with this puzzle then give the kids about 20 minutes to try and solve it.
While the kids are working on the puzzle I model trying to solve the puzzle myself on an overhead projector. I put the pieces on the panel, slip on my sun glasses and manipulate the pieces constantly and try to create a square 
Once the 20 minutes is over the pieces of the puzzle go into envelopes and are kept in desks. The kids are encouraged to take the puzzles home to frustrate parents. Heaps of fun for the whole learning community. hehehe
Have Fun
