Subitize the Dice / Quantity Total Fluency

This video is designed to help your students develop crucial subitizing skills using two dice. Subitizing, the ability to instantly recognize the number of objects in a small group without counting, is a foundational skill for early math fluency.

In this video:

  • We’ll flash images of two dice for 4 seconds.
  • Your students will practice quickly recognizing the total number of dots (sums from 2 to 12).
  • This fast-paced activity encourages mental math and visual recognition.

Why is subitizing important?

  • Builds Number Sense: Subitizing helps children understand that numbers represent quantities.
  • Strengthens Mental Math: It lays the groundwork for quick and accurate calculations.
  • Improves Fluency: Recognizing number patterns instantly reduces reliance on counting, freeing up cognitive resources for more complex problem-solving.
  • Engaging and Fun: Using dice makes learning interactive and enjoyable!

How to use this video in your classroom:

  • Use it as a warm-up activity.
  • Incorporate it into your math centers.
  • Play it during transitions.
  • Encourage your students to say the number aloud as soon as they see the dice.
  • Pause the video if needed to allow extra time.


This video is a simple yet effective tool to enhance your students’ number sense and prepare them for future math success. Let’s make learning fun and fast!
