Here is a new video I have made of some teachers who use subitizing with their students regularly. See Perceptual and Conceptual subitizing in action and you will understand it better!




See this link to Sharon Griffin’s website for even more fun with subitizing.  This video alone leads one to believe that you can jump right in with these bigger numbers.  See above video first to see what builds up to this ability.

    What I seen and got from this video is a way that we can assist our students and help them understand math in a modified way that will allow them to pay attention and think fast.

      Yes! And it also helps them see that they can access numbers in clumps rather than just a series of one. It helps kids see that numbers are composed of other numbers. 7, for instance, is not just the end of a serial count to 7, it is also a clump of 4 and 3 or 5 and 2, etc. Very powerful for students to understand as we prepare them to develop number sense within a base system where we need to think in groups and then powers of ten.
