  1. Dan,

    Thanks you so much for featuring Ruth’s Blog in your September round-up. Not only did you MAKE HER DAY/WEEK/MONTH with your kind and thoughtful words but as a thought leader in the math community you have inspired her through your validation.
    As a facilitator of the Cohort 21 learning community of which Ruth is a part of this is the kind of authentic moment we hope for. No doubt Ruth will continue to share with more passion and spark because of this new fuel.

    Thank you!

    Justin Medved

  2. After emerging from several months of first-year-teacher survival mode (they say this will get better the second year…do I believe them?), I decided to get back to the blog, which is when I discovered this post. Made my day (and it was already a good day)! Thanks, Dan
