Fresno teachers, welcome! Look for the yellow box below for material specific to you. You're welcome to look through the other materials as well, of course.


My blog, A Best-Case Scenario. Mostly about high-school statistics and modeling.

A set of videos about probability I made for my high-school (not AP) statistics class.

a page from Henri Piccioto on middle grades math.

Activities and materials from SERP. Check it out!

The Desmos Graping Calculator.

Data Games. Victory though data analysis!

Chips and Dip
This pdf describes a magical old math activity that's really about cooperation and the Tragedy of the Commons.

Linear models from EGADs
This is an early-2014 compilation of activities from EGADs (see below) that focus on linear situations. (Handed out in FUSD February 2014.)

The fabulous paragraphs activity. It's free! You have permission to copy it.

Grade 7 Sampling
These three activities form the backbone of a unit on sampling appropriate to Grade 7. (Handed out at the workshop in FUSD, April 2014.)

  • The Bean Counters. Sample from a collection of beans to learn the proportion of different kinds of beans.
  • Words on a Page. What's the average length of a word in a large page of text? Clearly, we should sample. But how? This activity uses three different techniques, and we find out which one is better.
  • Estimating the Crowd. Estimate the size of a crowd of people in a photograph. Learn how hard it is!

Grade 7 & 8 Area and Volume
This packet describes Common Core content about area and volume in grades 7 and 8, with commentary on what's hard and what the terms really mean. Includes some examples incluing the "home plate" investigation. (Handed out at the workshop in FUSD, June 2014.)

Grade 7 & 8 Polygon Areas
This packet contains the student and teacher pages for an activity in which students find the areas of polygons inscribed in a circle. We stat with triangles and work our way up. By the time we get to 360 sides, we've derived a formula for the area of a circle. (Handed out at the workshop in FUSD, June 2014.)

The Tinkertoy Derivation
Here is the derivation we refer to in the EGADS "Tinkertoy" activity. It derives the general form for going from a linear recurrence relation to its analytic counterpart. We didn't know what that meant either until we needed it to analyze the lengths of Tinkertoys.

Annals of Plausibility
You're teaching high-school or college physics. You want to assign open-ended investigations, but you need some structure. Here is a collection of "fake" physics papers. We propose these as an interesting genre of assignment. Students are to respond to a more-or-less theoretical paper by designing an experiment to test the theory. Ideally, they write a paper—in the same style—as a response.

Oh: and while all of the papers are believable, every last one is wrong.

We're tentatively calling it Annals of Plausibility. Send us papers of your own—and student work— and we will post them!

Erickson, Tim. 2014. "Nuts, Snook, Babies, and Nuts." In Sprösser, et al., eds, Daten, Zufall, und der Rest der Welt. Wiesbaden: Springer Spektrum.
This is a book chapter about modeling using nearly-cubic functions. The basic situation asks how the weight of hexnuts depends on their size. We discuss why it ought to be cubic, and why it turns out not to be.

Erickson, Tim. 2013. "Caging the Capybara: Understanding Functions through Modeling." In Wassong, et al., eds, Using Tools for Learning Mathematics and Statistics. pp 85–96. Wiesbaden: Springer Spektrum.
This book chapter shows seven different approaches to a classic optimization problem. We approach it at different levels of abstraction, and see how thinking about it in these ways gives us insight into how students can learn to use abstract symbols by starting with simple materials, measurement, and data.
