Penepico Montessori Geometry Area Shapes Set

Brand: penepico

Color: Yellow Triangle for Area

Features

• 1. 📐 See Area as Real Squares – Not Just a Formula – This Montessori geometry set includes yellow translucent plastic shapes (right, acute, obtuse triangles, parallelogram, rectangle, trapezoid) all printed with uniform square grids. Children count the grid squares to find area – proving that “area” means “how many unit squares fit inside.” Finally, area becomes visible, concrete, and unforgettable.
• 2. 🧠 “The hands are the instruments of man’s intelligence.” – Dr. Maria Montessori – Children physically combine two identical triangles to form a parallelogram, then transform it into a rectangle. By counting grids before and after, they discover that triangle area = base × height ÷ 2 – without memorizing a single formula. This hands-on derivation builds deep, lasting understanding.
• 3. 📏 Master All Elementary Geometry Area Formulas – Through guided exploration, children derive formulas for triangles, parallelograms, trapezoids, and composite shapes. They learn the critical difference between base and vertical height (using optional transparent height ruler) – correcting the common misconception that slanted side equals height. Perfect for ages 6-12.
• 4. 🌳 Premium Solid Beechwood Storage Box & Durable Gridded Pieces – The mortise-and-tenon beechwood tray (no glue, no nails) keeps all shapes organized, protecting them from loss. Each yellow plastic shape features a durable, easy-to-read 1cm grid. The set includes: right triangle, acute triangle, obtuse triangle, parallelogram, rectangle, trapezoid. Box dimensions: approx. 30 x 20 x 3 cm (11.8 x 7.9 x 1.2 inches). Total weight: 1.2 kg (2.6 lbs).
• 5. 🎁 From Counting Squares to Algebra – The Complete Geometry Progression – This material bridges pre‑number area sense (counting grids) to formal algebraic formulas. Ideal for Montessori elementary classrooms, homeschool, and math intervention. Also serves as a calming, structured activity for children with autism or ADHD, and as cognitive therapy for seniors with dementia – sorting and matching shapes stimulates spatial reasoning and memory. An exceptional birthday gift or Christmas present for budding mathematicians.
