Knobless Cylinders

Les cylindres de couleurs

4 sets of 10 colour coded cylinders that vary in height and diameter in 4 colour coded wooden boxes.

Yellow set: height and diameter of the cylinders decreases.

Green set: diameter decreases as the height increases.

Red set: diameter decreases as the height remains constant.

Blue set: height decreases as the diameter remains constant.

The knobless cylinders refine and apply the child's ability to discriminate dimension and prepare for mathematics activities involving comparison, grading and seriation.

The child initially orders a set of cylinders as a line or as a tower, later the sets are combined and the interrelationships in size are experienced.

These cylinders have a robust stained finish that is very resistant to chipping.

ELG: Shape, space and measures: children use everyday language to talk about size, weight, capacity, position, distance, time and money to compare quantities and objects and to solve problems. They recognise, create and describe patterns. They explore characteristics of everyday objects and shapes and use mathematical language to describe them.

WARNING: Not suitable for 0-3 years - Small Parts: Choking hazard.

Each wooden box is approximately 16 x 11 x 7 cm

These are finished with a robust paint which is not glossy.
