If a child is really confused about decimals, converting decimal numnbers into money is a great way to make things clearer. For example: a child may be asked to say how much bigger 1.3 is than 0.9. If they convert these decimals into money (£1.30 and 90p) they may find that they can do this calculation very quickly in their head, getting the answer 40p which they convert back into the decimal, 0.4. Demonstrating that money maths depends on decimal understanding is also an easy way to prove that decimals are actually useful in real life!
The goal of kindergarten math curriculum is to prepare children for first grade math:
~ To count by rote at least to 20, but preferably a little beyond.
~ The concepts of equality, more, and less.
~ To count backwards from 10 to 0.
~ To recognize numbers.
~ To be able to write numbers.
~ To recognize basic shapes.
~ To understand up, down, under, near, on the side, etc. (basic directions).
~ To understand the concepts of addition and subtraction with small numbers.
~ Expose the student to two-digit numbers.
