What’s your working number?

Ready for more Math for 2 and 3 year olds?

Find out what your preschooler’s “working number” is.  That’s the biggest possible number that your child can handle in his mind, even when he can’t see it.  He knows all of the possible ways to add and subtract to make that number.  The working number is the biggest quantity he can work with, at a 100% success rate.

Here’s how to find out what your child’s working number is.

There are three jelly beans. How many are under my hand?

Zero!

There are three jelly beans. How many are under my hand?

One!

There are three jelly beans. How many are under my hand?

Two!

There are three jellybeans. How many are under my hand?

Three!

When your child can get through all possible combinations with the number three, move on to four.  Then five, then six then… (you get the idea).

Finding out about your child’s working number gives you a glimpse into what he or she is developmentally ready for in math.

P.S. This activity is also an awesome way to keep young kids entertained while you’re waiting for food to arrive at a restaurant.  😉
