Subitize (again)

I know I’m late but it’s not too late for you to make a New Year’s Resolution.  Spend time each day having students subitize.

Here’s why you should consider it –

  • Everyone can improve their ability to Subitize and the ability to Subitize is correlated to improved computation skills.
  • It’s something you can do quickly – you can accomplish a lot in just a minute or two.
  • It’s something that will benefit every student.  You can have students subitize dot patterns (like the ones attached)  finder patterns,  5-, 10-, 20-frames, even up to 100.

The Math Coach has a great post about subitizing http://mathcoachscorner.blogspot.com/2013/04/cant-get-enough-subitizing.html

You can get some dot cards for subitizing here http://mathcoachscorner.blogspot.com/2013/07/using-dot-cards-to-build-number-sense.html
