Use the clues at the top of the grid to decide where to place the 9 shapes: 3 Crosses, 3 Triangles, and 3 Circles. Drag the shapes to the grid. When you are done, press Check Pattern. If the pattern is correct, the next pattern will appear. If there is an error, the board will clear and you can start over. At any time, if you want to remove a shape from the grid, you can click on the shape or press the Clear and Try Again button to clear the board. The first 16 puzzles are Warm-up Puzzles. The next 18 are Puzzling Puzzles. The last 16 are Super Stumper Puzzles. You can use the slider to go to any puzzle you would like to solve.
This Puzzle is based on a book by the same name by Carole Greenes and Tanner Wolfram. I thank them for allowing me to make this online game. See the link below for the PDF version of the book. These puzzles provide a tool for developing Critical thinking and creativity talents, including: * Solution identification and revision: Identifying and testing potential solutions, and revising when necessary.. * Spatial thinking: Interpreting information about position and form. * Persistence: Not give up when the “going gets tough”!
