Core Formulas
One-to-One Rule
1 \text{ touch} \leftrightarrow 1 \text{ number word}
When you count, touch each object only one time. Give each object its own number.
Number Group Rule
\text{Numeral} \leftrightarrow \text{Group of Objects}
The number symbol shows how many things are in a group. '3' means a group of three.
Last Number Rule
\text{Last number said} = \text{Total amount}
The last number you say when counting is the total. If you say 'one, two', you have two things.
