Yesterday Steve Valentine (@sjvalentine) and I turned in the manuscript for the second edition of a book we previously self-published with the title "Leading Online: Leading the Learning, Leading by Learning." This second edition will be published in print (!) with lots of new ideas and and observations from the past couple of years. Here is short passage from the updated introduction.

I made the infographic below using Explain Everything. The image came from unsplash.com, I put a blank rectangle with 70% opacity on top of that, and another yellow rectangle. The rest are some text boxes. You can grab the editable project file here. Steve and I will be able to share more details in the coming weeks and months, so please stay tuned!

It was pretty cool to read last month about a new mathematical discovery in the world of tessellations. A new class of convex pentagon that can "tile the plane" was discovered. Having taught Middle School math for many years and exploring geometric relationships through the study of regular and irregular tessellations, this is exciting news to me! In honor of this discovery I have created an editable Explain Everything project file that has 15 pre-configured slides each containing a class of irregular convex pentagons that tile. The last slide has the newest one.

To create this project file I first did some research on Wikipedia (it was reliable in this case). I then traced the shapes in Adobe Fireworks and created different colored and flipped versions and saved them in Dropbox. Then I imported the objects into Explain Everything and used the inspector to lock the scale and then duplicate. You can select multiple objects to set properties for without needing to group them. It allowed me to make 10x copies of 4 independent image objects. Finally, on the first slide I recorded a short example of the the objects being tiled and included some print instructions as well. Below is the recording from the first slide (the arrow points to the Play button in EE if you download the project file) followed by 5-second silent views of each of the other 14 class examples of irregular convex pentagons that tile. Enjoy!
