What is subitizing?

Subitizing is the ability to instantly recognize the number of objects in a small group without having to count them. When students begin subitizing they may count small groups in a set and combine or count one by one. Subitizing is a process that is learned over time with practice.

Why is it beneficial to students?

Learning to subitize can help students:

• Identify quantities more fluently and build confidence in math
• Build number sense by understanding number relationships (less, more, comparing)
• Recognize groups of counters quickly which can help with solving more complex problems later on
• Develop visual skills for recognizing patterns and arrangements in numbers
• Develop addition and subtraction skills by making it easier to combine or take away numbers
