Mathematics: Subitizing Fun!

In Kindergarten, we love to subitize! Subitizing (soo-ba-tizing) is recognizing a quantity without counting. It's easier to subitize smaller quantities, or quantities that are in some type of pattern. The kids have become really good at it! Here are a couple of our favourite subitizing videos that you can watch at home :) The kids know what the word subitize means... not that it's important, but it's just a part of the song ;)






Why is knowing how to subitize important? It's attaches the quantity of a number to the numeral, and it's the perfect way to transition into addition. Subitizing goes hand in hand with counting on (starting at a number and counting on, instead of counting from 1 again). Once we acquire these two skills, it's makes adding easy! We can also maneuver dots or objects in our head, which actually leads to regrouping!

For example, one of our student's thought process for adding these was:



"I know that's 9, if I move 1 dot over here, it makes 10, which is 10 and 1, which I know is 11!". 

Watch one of our students perfect their subitizing skills below!
