Helping children become mathematicians!

Calgary City Teachers’ Convention: Seeing Dots February 10, 2016

100 dot array picThe 100 Dot Array remains one of my favourite tools for helping students visualize numbers. This session at the CCTC focuses mainly on its use with students in grades 2 and 3, although it can be used at many other grade levels. We will be talking about the best way to introduce the tool to students, showing an early activity to help with general number sense, and using the number in problem solving situations. A variety of problem are included to show its diverse use.

Here are the downloads available from the session:

Please let me know how it goes with using the 100 dot arrays with your students! I love to hear about kids using tools and strategies in math.

Mathematically yours,

    Hello 🙂 What an amazing site! I’m glad I found it – I’m from New Zealand 🙂 Just wondering how one can access your 100’s dot array and your other resources as the dropbox link says the file can not be found or has been made private.
    Thanks so much!

    • Hi Yvonne. Can you please email me directly and I will send you what you need. Yes, the dropbox links are no longer working and I have not yet decided how I am going to change things. Email address is in the “about me” section on the site. 🙂
