Number concepts are tied to the world around us. It helps us make sense of the world.

## WE COUNT

We count to know how many things are in a set.

We count things of the same set. One egg, two eggs, three eggs…in a basket. What you are counting is called the unit. The unit is the standard measurement used for that one thing being counting.

## MORE, LESS, AND SAME

Numbers relate to each other. The number 7 is more than 4; 7 is two less than 9; 7 composes of 3 and 4 as well as 2 and 5; is three away from 10.

Look at the sets of eggs.

**Question**: Which set is more? Which set is less? Which are the same?

* Answer*: Set D is more than than A, B, or C. | Set C is less than A, B, or D. | Set A and B are the same.

Now look at the egg carton. How many eggs can hold in this carton?*Do we have enough eggs to fill the carton? Would we have any egg or eggs that will not fit in this carton?* By how much less or more?
