About This Lesson
In these puzzles, the children need to use what they know about the geometric shapes of triangles and squares in order to solve them. The problem cannot be solved, unless the child can recognize the shapes. It is even more helpful to be able to visualize the shapes when they plan which toothpicks to move. Some children may find it helpful to draw their solution attempts to keep track of what worked and what didn’t. Students will be able to share strategies to solve puzzles using geometric figures.
