S-6800 Angle measures 角度學習器

S6800A Protrator (2pcs)量角器

This 4"(10cm)180?protractor includes all the features of our separated scale SAFE-T Protractor?plus the added benefit of a 𢘫emory ray?to set and record angles. The ray extends past the base of the protractor to capture angle measurements from 3 dimensional objects. Shatter resistant SAFE-T Plastic?makes this protractor perfect for student use and the View-Thru?plastic allows for use on overhead projectors.

This 6"(15.5cm) 180?protractor is actually two protractors in one. With slotted separation, lower scale reads right-opening angles (<), upper scale reads left-opening (>) angles. Orange, shatter resistant plastic. Separated Scales.
　

S-8720 Dynamic geometry(Student)幾何扣條

S-8721 OverHead Big Dynamic geometry透明大幾何形扣條

AngLegs is in 6 different lengths that easily snap together to motivate students to explore plane geometry on their desktop. projector. Students will discover what happens when they use all the same lengths legs verses different length legs to build various polygons. As they attach additional legs they study polygon heights, calculate their areas, find center points and much more! This 74 piece set consists of 72 AngLegs 12 each of 6 different lengths in six colors.

Size: orange/5cm+purple/7cm+green/8.66cm+yellow/10cm

+blue/12.12cm+Red/14.14cm12pcs=72pcs

A great visual aid for teaching angle measurement and polygons to a large group of students at one time. These six AngLegs range in length from 11.5 to 30 cm. Each length is a different color (orange, purple, green, yellow, blue, and red) and snap together easily to form effortlessly manipulated shapes. Set includes two special 6" Protractors that simply snap onto the AngLegs for angle measurement. 26 pieces

Coming Soon

At last, the perfect 2 cm building cubes. Geo Cubes are designed so that all of the peg sides of the cubes can be concealed to create a flat surface, allowing for perfectly symmetrical geometric figures. Use for exploring symmetry, geometry, area, volume, measurement, operations, factions, and more. Geo Cubes connect and separate with ease. Available in four different interlocking shapes: cubes, right triangle, equilateral triangle, and quarter rounds for creating rounded shapes. These cubes allow for a unique construction of an offset assembly pattern, that no other cube allows, in order to form pyramids or towers. Geo Cubes come in assorted colors.
