Explanation
A dice has dots on its faces. The dots tell the number. Three dots show 3. Six dots show 6. With practice we can see small numbers without counting. We can also show numbers with our fingers. Five fingers on one hand show 5.
Worked examples
This dice shows 4 dots. This dice shows 6 dots.
Two dice. The first shows 2. The second shows 5. 5 is more than 2.
To show 7 with fingers, show 5 on one hand and 2 on the other hand.
