#awesomegraphs.2

The summer of 2017 featured a significant number of flooding events in and around Indiana County. Several storms dumped a significant amount of rain over a short period of time, overwhelming local creeks and other stormwater runoff causing flooding in many residential and commercial buildings.

Below are data collected in the Marsh Run, and other named streams. Thanks to water expert Dr. Katie Farnsworth from Indiana University of Pennsylvania and her water monitoring project for making these possible.


1. Study the graph above. Write 6 lines describing what information is shown.


2. If you haven't already, describe what the orange and blue lines represent. How do they relate to eachother?




3. Study the graph above. Write 6 lines describing the data presented here. Why does it have the odd jagged shape that it does?


4. What time was it raining the hardest?

#awesomegraphs use data and visual mathematical modeling to tell a story. This blog helps students discover the math behind the data behind the story.


Study the #awesomegraph from the New York Times below.

Write for 5 minutes about the information you see in the graph above and at the link.


1. Why will it be hard to beat Peyton Manning's Record?  How is Manning's graph different than the others? Write three lines.


2. What would the steepness, or slope measure? How does Peyton's line compare to good ol' Sammy Baugh?



3. In the middle of Peyton's line is a flat part. What does this mean? Write at least two lines.


4. Johnny Unitis is a local legend in Western Pennsylvania. Use his line of touchdowns to describe his career.


5. Pick another player. Describe their careers based on the number of touchdowns they've thrown per year. Find a picture of them and paste it here.

Thanks for Desmos Teaching Fellowship

I clearly haven't been updating this blog much, but following the previous post, I've recently been awarded a Desmos Teaching Fellowship. I'll receive an expenses paid trip to Desmos.com headquarters in San Francisco in November, and an opportunity to help them develop their teaching applications.

Since our students are 1 to1 with Chromebooks, I've been using both the pre-made, and the custom Desmos activities in all of my classes. Last January, I presented a workshop to a group of colleagues on using the activities. Here's the presentation and the PPT. Most of my math colleagues now use Desmos.com in some way or another.

Hopefully more updates to come!

Desmos teaching applications

I've been researching teaching applications of Desmos.com. I came across this - which looks awesome.
