Subitizing is the rapid and accurate identification of numbers used to assess small quantities. Knowing how to subitize (or recognize small quantities without having to count them) enables students to gain automaticity and numerical fluency. They can add and subtract faster. They are more confident in their abilities. In my subitizing activities center , I also incorporated number words, as an added skill students can practice and a way to incorporate literacy into my math time (we will fit literacy in whenever we can!) So, why is it important to have a math center focusing on number recognition, quantity (subitizing), and number words? Students need to be fluent in reading and math. Number words come up on many occasions in text (one specific example is the DRA assessment). Numerical fluency is important in problem solving. Seeing representations in your mind of the quantity of a number can help with adding more on, or taking away, or even grouping (tasks that require mu...
