I am always looking for materials and ideas to improve the geometry area of my classroom. A few months ago I ordered tangrams and pentominoes for my students. I also came across a binder full of tangram and pentomino puzzles.
Although not tradition Montessori materials theses puzzles meet the criteria of Montessori standards. They are tactile, designed to achieve a specific end, and are inviting. Moreover they assist students in learning shape nomenclature, angles, transformations, symmetry, congruency, similarity, spatial development, problem solving skills, fine motor skills, awareness of area, imagination, and creativity.
The activities in the binder progress in difficulty. They begin by asking students to match tans and create congruent shapes. Moderate activities ask students to fill a space using specific pentominoes or using x number of tangrams. The most difficult puzzles require students to find several answers and graph their results.
My students enjoy these puzzles and it gives them a rest from nomenclature and definition work. They love exploring the shapes and solving each challenge!
