# Number Concepts – Understand how to use numbers

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?
