They love the big squares (4 normal tiles large), the ones with wheels, and the normal sized squares. I bought the 8 Piece Expansion Set of rectangles and squares when it used to be available. I wish I had bought more. The large squares help stabilize large buildings. Like this:

They also love the smaller rectangles you get with the magnatiles builder construction set. That set was also a hit. If you have a kid who likes vehicles, I recommend it.
