    1. Jason,
      I uploaded an updated version of the documents in both word and pdf. Please let me know if you have any further issues. Also, please share how the lesson goes. I’d love to hear about your results!


  1. You’re welcome. Sounds like you’re building a passion for math in your students. Keep it up. And please share more of the work you do with your students. Maybe start a blog of your own? 🙂

  2. I’m planning on doing this math task in the AM! Also starting to work toward inquiry in mathematics…how do you view inquiry in math versus inquiry in science? I am BRAND new to true inquiry so I would love to discuss this with you.

    Also, I have written a couple of pretty neat (if I do say so myself) math tasks…do you give constructive criticism?

    1. Tamara,
      Great. Please share the results of your lesson. I’d love to hear how it goes.

      Inquiry in science seems built in. We’re asked to notice and make observations and question in science as early as kindergarten. That doesn’t seem to happen in math, unfortunately. I think it can be just as powerful, but it requires an instructional shift toward a more student centered approach and away from a teacher centered approach. This can be scary because we’re asking teachers to give up control. I could go on forever with this, but that’s a start. We can continue this conversation via twitter and we’ll probably get input from many others engaged in inquiry!

      I’d love to see your work. You can send it to me via email. Just click contact me on my website. Or throw it out on twitter and tag me: @mikewiernicki. Looking forward to continuing the conversation.
