A set of blue Geometric Solids used for the calculation of volume. The solids are derived from a base of 10 x 10 cm and a height of 20 cm. Each sold individually.

Sandpaper Numerals are ordered separately.

A control chart for the Geometric Cabinet, showing the 26 geometric shapes. Printed in blue on white plastic.

This material is used to represent in geometric form the hierarchy of number for: 1, 10, 100, 1000, 10,000, 100,000 and 1,000,000. The precise nature of these materials makes it...

The Red Rods develop visual discrimination of length, while height, color and width remain constant. Ten solid wooden rods increasing in length in equal units from 10 cm to 1...

Used to help isolate the possible number combinations of 1 -10, the Bead Houses are made of durable plastic and color-coded to correspond with the Bead Material. To be used with...

Additional exercises for use with the Geometric Cabinet Includes: exercise cards, divider tabs and a wooden box for storage.

This 2-compartment box with lid contains plastic chips, 1 set with equations printed on them and 1 set with the answers to be used with the Addition Working Charts. All the...
