How Subitizing Fuels Number Sense

How Subitizing Fuels Number Sense

Doug Clements shared insightful information regarding the value of subitizing.

3 BIG takeaways from the session:

  1. Subitizing and counting grow together.
  2. Perceptual subitizing is the ability to see as one amount, versus conceptual subitizing is the ability to see as parts. BOTH are important to mathematical development!
  3. Subitizing is “not an age thing,” as Doug states in the session. Once students acquire conceptual subitizing to 10 and 20, they are able to develop visualization of mental strategies for basic facts and beyond. You can even incorporate subitizing with place value blocks, discs, and multiplicative reasoning.

Mathodology supports teachers and students with basic fact fluency materials to integrate within the implementation of mathematics curricula. Preview our Quick Looks that provide subitizing opportunities for building knowledge around the basic facts.

Teachers with the online teacher tool kit, Quick Looks for addition have now been added to the Fluency section of your tool kit!
