Antislide-Tetramino Puzzle

Antislide-Tetramino Puzzle Please note that the color of this puzzle varies. The Antislide-Tetramino or AT-Puzzle was created by the talented Russian designer Vladimir Krasnoukhov for IPP35 (International Puzzle Party) which was hosted in Ottawa, Ontario, Canada in 2015. This puzzle consists of five tetramino elements and a rectangular frame. Goal 1: Pack all the elements in such a way that no element can move within the frame (‘anti-slide’).  Please use the orthogonal grid (graph paper is an example of orthogonal grid).  There is only one solution! Goal 2 (Warming Up): Make a symmetrical shape using all the elements (either inside or outside the frame.)  

The first thing you see when looking at any puzzle is the photo or illustration of the completed puzzle. On choosing, remember that the image should have some educational value but also be something the child can relate to. If the image is familiar to the child or fulfills the educational objective (like learning colours or naming objects), the experience of completing the puzzle will be all the more enjoyable, satisfying and productive. The image should be easily recognizable so the child can identify it as something they see around them in their everyday life. It should also have distinguishable features to help them decide where to put the piece so that it ends up in the right place.
