NUMBERS
numbers and counting
THERE ARE MORE THAN WHOLE NUMBERS
numbers come in all shapes and sizes

Following on from early learning, we begin to realise that we need to represent the quantity of things in more than ones and twos.

Here is a list of different types of numbers: 
Whole numbers                   0, 1, 2, 3, and so on
Natural numbers                  1, 2, 3, ->
Integers                            <-   ,-3,-2,-1,0,1,2,3, ->
Fractions
Percentages
Decimals
Numbers in a different base (e.g. binary, octal, hexadecimal and so on)
Real numbers
Rational numbers
Irrational numbers
Imaginary numbers
Cyclic numbers
...

Before secondary school we should concentrate on introducing fractions and decimals, a context for negative numbers (below zero BRRR), with the irrational number PI thrown in for good measure.

I would keep numbers in context for these learners.

Here is a nice link for learning about the different types of number.
