I Can...Subitize!

Let me just say that my student teacher is awesome.  She did her first solo lesson today and for real, this girl is a natural!  I snapped a few pictures during her math lesson so I could share them with you!

This week we are beginning number identification 0-5.  When I pre-assessed last week I learned that 100% of my students could already recognize those numbers.  Of course, we know that just because they can identify the number doesn't mean they actually understand it.  After talking with Kathryn, we decided that it might be best to take this week's math in the direction of subitizing.  If you are not familiar with the term, it simply refers to the recognizing of groups automatically without having to count the individual items within the set.  {Think dice.  You can look at the dice and know what number it lands on without having to count the dots.}  Subitizing is an important step in gaining true number sense.
She gave each child 2 sets of spoons: clear ones with the numbers 0-5 written on them and white ones that had dots in the amounts of 0-5.  She had the students lay all of their white spoons out on the table and hold the clear spoons in their hands.  She would call out a number and the children would find the spoon with that number on it and lay it on top of the spoon with the corresponding amount of dots. Adorable, right?  Simple. Cheap. Fun.  I LOVE it!

She also had index cards with dots on them for the kiddos.  She would call out a number and the kids would find the dot card as quick as they could and hold it up.  What I love about this is that the cards had the dots arranged in different ways.  So on one card "4" might be represented with 4 dots in a vertical row.  On another card the dots might be in the corners of the cards.  I can't wait to see what she will do with them next! :)


  1. GENIUS!! Love this idea and WILL be borrowing. Tell her thank you :)

  2. I have also used the "yard sale" round stickers on paper plates to make "dot plates" and used these in whole group and small group to help my students with this. I used 2 colors so we could also reuse them with addition later (I see 3 red and 4 green, 7 in all)

  3. I love this idea!!! Thanks for sharing! Can't wait to try it with my Kinders! :)

  4. Wow! I love your student teacher's lesson. I pinned in to my "Math" board on Pinterest and will use it soon as a review with my students. Thanks for sharing!

  5. Great idea!! Sounds like she is a natural!!

  6. Ah, I miss the student teaching was just 3 years ago, but seems like f
