Hands-On Math: Subitizing Course

Build Number Sense and Fluency Through Subitizing

Help students move beyond counting one-by-one toward confident, efficient mathematical thinking. This hands-on micro course explores how subitizing - the ability to instantly recognize quantities - can strengthen early number sense, mental math, and flexible problem-solving. Through practical routines using subitizing cards, educators will learn how to help students recognize visual number patterns, develop part-whole relationships, and explain their mathematical thinking while building lasting fluency.

By the end of this course, learners will be able to:

• Explain how subitizing supports early number sense and mathematical development.
• Facilitate subitizing routines that build flexible number thinking and fluency.
• Apply effective questioning strategies to extend student reasoning and strengthen part-whole understanding.

Target Audience:

• Math Teachers and Coaches

Format:

• Self-paced eLearning course with interactive knowledge checks and real-world scenarios.
• The estimated time to take the course is 20 minutes.
• Downloadable lesson plans on how to support student understanding of number patterns and decompositions with subitizing cards geared to Kindergarten, 1st, and 2nd-grade students, and can be adjusted to meet the needs of your students.
• A completion certificate is available after completing the course.
