Subitizing

Are you teaching your young math students subitizing? You're probably on the hunt for subitizing worksheets, activities, and games to make this math skill stick in those little minds! The Teach Starter teacher team has put together a complete collection of teacher-created printables and digital options to teach students how to subitize so they develop a strong mathematical foundation in kindergarten and first grade to build on throughout elementary school.

What Is Subitizing in Math?

Is this your first year teaching this part of the math curriculum, or your first time in a few years? Don't fret! The math teachers on our teaching team have put together a quick refresher on the definition of subitizing and some tips on how to teach this crucial math skill. Subitizing is the ability to instantly recognize the number of objects in a small group without the need to count them. It's essentially "seeing" amounts of things without being given a number in digit form. For example, when a student rolls a die, if they can instantly recognize the number of dots on its face, that's because they know how to subitize. Subitizing in kindergarten and 1st grade is all about helping students to relate numbers to actual items or groups of items.

How to Teach Subitizing

It's an important mathematical concept, but just how do you teach subitizing? The key is to expose students to number patterns so they can begin to compose and decompose numbers mentally, setting the stage for "seeing" those numbers in small groups of objects. To help you get started, our teaching team has put together dozens of resources, each of which has been reviewed by expert teachers to ensure they're classroom-ready. Inside this collection you'll find:
  • Subitizing sorting activities
  • Subitizing games
  • Printable worksheets
  • Counting activities
  • And more
