Guides: Kits and Manipulatives: Geometry

AngLegs

AngLegs are line segments that can be joined together to created closed figured polygons.

AngLegs
The set consists of 74 AngLegs (12 each of 6 different lengths in 6 colors), two snap-on View Thru protractors for desktop or overhead use and 15 double-sided activity cards. These flexible sticks in 6 different lengths easily snap together for great fun in exploring plane geometry. Start with two AngLegs of any length and snap on the special 4" protractor to explore angles. Then, add a third leg for triangles, a fourth for quadrilaterals, etc. Students will discover hands-on what happens when they use all the same lengths verses using different lengths to build their polygons. The included activity cards for K-2, 3-5, and 6-8 are full of discovery activities and adhere to NCTM Standards for geometry.
Grades: K-8

Elementary geometry

Elementary math and geometry

New primary link-a-board caddy pak
Collection of geoboards for classroom use - 20 geoboards included in each pack.
The show and tell geoboard collection
This resource focuses on hands-on activities using geoboards and geopaper to develop understanding of patterning, counting, two-dimensional figures, slides, and flips. It includes project work, group work and individual assignments that emphasize integrating language arts and mathematics. Teachers notes, black line master activity sheets, and evaluation techniques are provided.
Grades: 2-4

G-O frames

G-O-Frames (Geometry-On-Frames) are a set of 7 standard 2-D geometric shapes that can be hinged together to create 3-D platonic solids. 3-D solids can also be de-constructed and laid flat to show how a 3-D platonic solid is made.

G-O-frames starter kit
A set of 7 standard 2-D geometric shapes that can be hinged together to construct 3-D platonic solids.
Getting started kit for - G-O-frames
Contains an assortment of geometric shapes and a teacher's guide.

Geo-mirrors

Geo mirrors reflect images for lessons in symmetry, congruency, lines and planes. They assist students when drawing angles, bisections, perpendicular and parallel lines.

Getting started kit for - Math-Vu mirror
A mirror geometry instrument. This item can be used on the overhead projector to demonstrate for students or by students individually. It consists of 7 Math-Vu mirrors and a teacher's guide.
Ray's reflections mirror lab
To help students learn the elementary geometry points, lines, and angles by investigating the reflection of light from one or more plane mirrors. Kit contains various size mirrors, holders and an activity guide.

Solids

Tangrams and Pentominoes

Tangram puzzles assist with the study of plane geometry - shape names, transformations (flip, slide, turn), angles, symmetry, and interrelationships among shapes. Problem solving skills and strategies are refined by: trial and error, visual analysis of space, perseverance, and predicting.
