Solving puzzles with a child will help develop his logic and non-standard thinking. But the kid is not always interested in straining his convolutions over someone else's toy. The puzzle made by the child himself will always be interesting to him.
How to make a puzzle
First you need to make 13 puzzle pieces. Chips are made with a diameter of 5 centimeters. Thick cardboard or plywood up to 10 millimeters thick is best suited for their manufacture. If there is no thick cardboard at hand, then you can glue several layers of plain paper and cut the chips out of it, after waiting for it to dry completely. If the chips are made of plywood, then it is necessary to process the edges with a thin file to avoid injury to the child.
The counters need to write numbers from 1 to 13. It is best to use a black permanent marker, but regular acrylic paints will work. The contour of the chips is highlighted in a different color for better perception.
The workpiece itself, in which the chips will move, must be made from a sheet of Whatman paper. The diameter of the chip made will dictate all the other dimensions of our workpiece. According to the figure, mark the future workpiece on a Whatman paper. Cut out the outline of the puzzle. Make cuts in the workpiece where the solid lines are shown. Bend the edges of the workpiece up to form a chute for moving the chips. The resulting puzzle model is not yet solid. For added stability, glue the edges, which are shaded in orange, together.
How to play the puzzle
The pieces are placed in random order along the length of our puzzle. The side pockets remain free. Using these side pockets, you need to move the pieces so that they line up in order from 1 to 13, or vice versa. Time yourself. Now shuffle the chips and invite the second player to do it faster. The one who builds the chips in order faster is the winner.
You can add complexity to the puzzle in different ways. A sheet of paper can be placed in the chute, in which the order of the final construction of the chips is written. Since the sheet of paper will initially be hidden by the chip, the initial number can be recognized only by freeing this sheet of paper.
You can come up with various ways to finalize the chips. For example: the odd numbers of the chips are ascending, alternating with the even numbers that are descending. Such constructions will make you think a lot about this puzzle.
