Pin of the Week: Subitizing

This week's pin comes from My Explorations in EC Mathematics. Thanks to Tricia Stohr-Hunt for the pin.

What is subitizing? Getting a turkey and cheese sub when a roast beef is not available? No, although turkey and cheese is not a bad substitute sub. Subitizing is being able to look at a number of items at a glance and knowing how many are there. Why is subitizing important? Being able to subitize means you can see parts of a whole. For example, you can see three and two in a set of five objects. This is a great skill to have when you are working with number families.
