Knobbed cylinders
SOLD OUT Please see Discount section.
This set is of the very highest quality: precision engineered and beautifully crafted.
Each cylinder slides effortlessly yet precisely into its well, giving the child an enormous sense of satisfaction.
Set 1: height and diameter of the cylinders decreases.
Set 2: diameter decreases as the height increases.
Set 3: diameter decreases as the height remains constant.
Set 4: height decreases as the diameter remains constant.
The knobbed cylinders introduce the visual discrimination of size, they refine the child's perception of dimension and prepare for mathematics activities such as comparison, grading and seriation. The blocks provide a control of error and even a young child can use them successfully.
The child initially works on one block at a time, later the sets are combined and the interrelationships in size are experienced.
ELG: Use language such as 'greater', 'smaller', 'heavier', or 'lighter' to compare quantities. Use language such as 'circle' or 'bigger' to describe the shape and size of solids and flat shapes.
