Big and Small

Understanding concepts of  big and small are important for math readiness. A main concept of mathematics is understanding degrees of big and small. Preschool children love talking about how big they are compared to other things. For example, children love that they are bigger than their cat, baby brother or sister, or a stack of blocks.

After a child understands about different sizes,  he or she is able to understand about less and more , larger than , smaller than , and equal to or the same as .

Here are some pink tower cards to help refine the concepts of size. For younger children, use the small and big cards first.

Use one set of cards at a time. For example, start with the big card, bigger card and biggest card.

The second set of printouts can be used as reading cards and the first set can be used as a control card.


Check out books about size at your local library. Look under key words such as big, little, small and large.



Dramatic Play

Make a circle in front of your face using your arms. Make each ball bigger as you say the finger play. Lastly, make the balls go from big, bigger to biggest.

I have a big ball.

Here is a ball that is even bigger.

Here is the biggest ball ever!
