The Montessori geometric cabinet and metal insets are among my favorite Montessori materials. They can be expensive for homeschoolers and environments other than Montessori schools, though. Fortunately, there are inexpensive alternatives.
Although the geometric cabinet is considered a sensorial material and the metal insets are a language material (preparation for writing), you can create materials that will work for both. Here are some great ideas from around the blogosphere for making your own geometric shapes that can be used instead of a geometric cabinet and metal insets. To isolate the difficulty, it’s best if you keep the shapes the same color and size, varying only in shape.
