The correct number of spindles is provided.

AIM:

To reinforce the child's understanding of number names, numerals and quantities.

POINT OF AWARENESS:

Separate items may make up a single quantity. Nothing is places in the zero compartment: "Zero is an empty set."

2. Give child the chance to answer, so you need to pause and waiting for him to reply.
