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
