  1. I watched the series this morning Steve. Thanks for the introduction.

    Mathematical language is very important. Students and teachers that I work with tend to substitute a synonym instead of the formal terminology –which causes anxiety.

    Have you encountered many teachers using the word “grouping” in lieu of subitizing?

    1. I haven’t noticed that particular substitution, but I have noticed that subitizing is a word that is seldom used.

  2. Steve, Your animated subitizing series is an amazing resource. You might be interested to know that the new edition of Everyday Mathematics, which my district will be adopting, now includes subitizing dot cards and activities as part of its primary grade routines. I plan to use your videos to help our teachers understand the idea and importance of subitizing as part of their PD.

    1. Thanks for sharing, Joe! I’m glad that this will be a helpful resource in your district. I’ll be posting more soon!
