Subitizing to Enhance Number Sense in Elementary Math Education

Slide Note

Explore the importance of subitizing for developing number sense in elementary students. Discover strategies to help students organize quantities efficiently by tens, recognize place value, and engage in skip counting. Use visual aids like ten frames to support conceptual understanding and reinforce key learnings. Overcome challenges with disorganized arrays of dots by understanding the limitations of our brain's processing capacity. Practice subitizing to 20 with a focus on organizing and recognizing quantities effectively.

Level C6 Level C6 Starter Slides for this level Subitizing Level Key Messages and Student response expectations Critical Learning Phases (KR)/Learning Tractories (C&S)/Standards (CCSS-M)/ Key Learnings (VF or citation) Conceptual Subitizer to 20 (C&S) Conceptual Subitizer with place value and skip counting (C&S) C5 with 10s Why was that so hard to see? (disorganized array of 12 or more) Dots all over the place Remember, our brain doesn t process more than 5 or 6 dots at a time so we need to get organized to see more dots! In our number system we organize quantity by tens. How about this? (flash ten frame and some extras) Real Name? One ten two ones! Nickname? 12! Show two and three tens frames as well for a responses such as: 2 tens! The nickname is 20!
