The Montessori math materials are provided for individual math activities to explore plane geometry and measurement at all levels. These variety packs of colored Anglegs comes in different lengths that allow kids to build polygons of their choice. The angle pieces are magnetic for demonstrating angle measurement and polygons to the entire class. As they attached additional legs, students study polygon heights, calculate area and perimeter, and find center points. Math angle strips are easy-to-manipulate, adjustable so that they can be snapped together. Snap together the AngLegs that comes in 4 lengths and 4 colors to create a multitude of different geometric shapes like triangles, squares, polygons, and rectangles. The large AngLegs pieces measure from 25 cm closed to 50 cm expanded. AngLegs make learning angles, geometry, shapes, and measure engaging for your kids. These math manipulatives allow your students to develop a deeper understanding of angles through hands-on experiences. AngLegs are Montessori math themed, meaning that they're hands-on for kids to learn on their own. Kids can measure angles by snapping 6 inch protractor onto the angle vertex. This set include 16 AngLeg pieces, 2 Snap-On clear protractors, and 1 activity guide. For over 50 years, hand2mind has encouraged hands-on learning and discovery, driving deeper understanding and helping children unlock their full potential. Hand2mind specializes in math manipulatives designed to help students learn by doing. Particularly with learning shapes, hand2mind has you set with geometry sets, compasses for geometry, protractors, rulers and all necessary school supplies.
