Our EI services are ending soon and I want to buy some of the puzzles that LO's teacher brings over every week. There is no brand listed on the puzzles and she bought them at a garage sale...

They are wood puzzles that have shapes of a dinosaur, car and train with a lot of pieces and no guidelines on where the pieces go...lots of trial and error. They are similar to this tangram puzzle.

Any suggestions? I looked online at some learning websites and didn't see anything similar!
