A Response to ‘Worst Discount Ever’
On his awesome blog, Mr. Honner recently put forth a terrible discount and solicited worse discounts. This might by cheating somewhat because I found it online, but still…. On the flipside, it is eligible for Amazon Prime shipping.

Update to previous post on weather: holy cow, WolframAlpha is amazing!
Previously, I tossed out a weekly local temperature plot and asked if you could tell when it started snowing. I also posited that it might be an interesting take periodic motion and/or sine curves. The problem is, not every locale has a nice cache of temperature and dewpoint data. Or do they? Enter WolframAlpha. It’s…

7th and 8th Grade additions to the Great Inquiry-Based Curriculum Mapping Project
If you haven’t read last week’s introductory post or description of the Great Inquiry-Based Curriculum Mapping Project, please do so. Here’s the short description: there are some open google docs that tie math standards to activities, problems, projects, blog-posts and/or ideas. There have already been some great aggregation of ideas and the documents continue to…

Introducing: The Great Inquiry Based Curriculum Mapping Project: a plea for collaboration
I’m kind of tired of working by myself. I’m just not smart or creative enough to create an entirely inquiry-based curriculum. You know, the kind of curriculum where you pose an interesting problem to your students and let them attempt to solve the problem, and the teacher becomes more of a facilitator and intervenes, when necessary, rather…

OK, I’ve tweeted about it. Several times. @IngridRistoph is probably tired of her twitter notifications buzzing, but she tweeted it out last night, and I retweeted it about a hundred time. So huge hat-tip to her. (Update: Ingrid went ahead and started a blog, after being inspired from her discovery. Google Reader bookmarks at the…

Be sure to check out Part 1 of this post, when the activity was assigned (i.e. if you were absent from E/M yesterday). There I provided my data on the number of Charlie Sheen’s twitter followers and the time. I hypothesized that it would be a more-or-less exponential growth curve. I’ll break this up into a few…

Can someone help me with my 5-year-old daughter’s Math homework? (Part 2)
So remember the first part of my quandary about my kid’s math homework from this morning? Well, now I’m on the next question and I’m stuck again. I’m not sure what “do we see” means. Does it mean how many hats of the 17 do they both see? That could mean this. Then again, “hats…

Can someone help me with my 5-year-old daughter’s Math homework?
I’m being serious. It’s due tomorrow and I have no idea how to answer the following question. Now, the answer to this is obviously “four.” The narrator has four cats. The number of cats his or her friend has is irrelevant to the question. I’m just not sure how to fill in the pictures and symbols. Here’s…
