Key Mathematical Ideas

Numbers between 0 and 1 can be expressed using an extension of the whole number place-value system.

There are different ways to represent decimal numbers with diagrams and physical objects; each representation must include a means to show that adjacent places have a ratio of 1 to 10.

The same principles that govern whole number addition and subtraction apply to addition and subtraction of numbers involving decimals.
