Subitizing is the ability to recognize an amount of dots or objects without counting. This begins with numbers on a die and increases to larger numbers . Subitizing leads to automatic number recognition because of the ability to visualize quantities.
Make subitizing a hands on lesson with unifix cubes. Transfer automatic recognition to other objects or numbers words.
This may be used as an individual math center or a whole group lesson.
I use this daily during my morning meeting and in my math centers.
