What is Subitizing?

Subitizing is a skill that involves quickly recognizing quantities without counting. As students develop their subitizing skills, they move through different phases, or levels, of subitizing:

• Perceptual subitizing
  This is the first phase of subitizing, and involves instantly recognizing small quantities, usually up to five. It's instinctive, and is often taught first because it's a building block for the next level. For example, a student might quickly name the quantity of four gems as "four".

• Conceptual subitizing
  This phase involves identifying the quantity of smaller groups within larger sets, and then combining them to name the total. For example, a student might see two fours in the eight of a domino. This phase requires more thought than perceptual subitizing.

How Do I Use These Cards?

. Simply print, cut, and laminate (these can be used over and over again for years to come)

. Encourage students to look at each card and group the numbers to get a total. This can be accomplished by counting each dot and adding together or by subitizing

. Promote fine motor skills by having students mark the correct answer with clothespins. You can differentiate for students by having them place buttons, pom-poms, or other small objects on the numbers as they identify them.

Suggested Uses:

. Assessment tool to determine students subitizing level

. Add to math centers for students to freely explore and count

. Add to morning boxes or busy boxes for students to complete

. Use as part of small group work to assess counting principles (stable order, correspondence, cardinality, abstraction, and order irrelevance).

. Use as part of transition times as (lining up, walking in halls, handwashing) to have students subitize while they wait
