### Math in Real Life - Why Airlines Overbook Flights

I'm currently flying home the ESC-20 Library Resource Roundup in San Antonio, Texas. Before I boarded the flight the gate agent was looking for volunteers to take an alternate flight due to overbooking. This seems like a good time to share the TED-Ed lesson Why Do Airlines Sell Too Many Tickets?

In Why Do Airlines Sell Too Many Tickets? students can learn about the mathematics that airlines use to maximize the revenue that they can generate from each flight. That math includes calculating the probability that everyone who holds a ticket for a flight will actually show up for the flight. The way that probability is calculated is explained in the video. Finally, the lesson asks students to consider the ethics of overbooking flights. Watch the video below or go here to see the entire lesson.

### Fall Time-lapse - A Video Project

The fall is my favorite season of the year. I love waking up to cold, crisp mornings then enjoying mild days outside. In fact, that's what I'm planning to do tomorrow morning. This time of year always reminds me of one of my favorite uses for time-lapse video creation tools. The outline of my time-lapse of autumn project is included below.

The idea is to take one picture every day to document the changes in the foliage as we progress through autumn from the first few orange leaves to full-blown autumn foliage colors to the drab brown we see after in the winter.

Here's how your students could create their own autumn foliage time-lapse videos.

1. Take one picture per day of the same view or of one singular tree.
Using a cell phone is probably the best tool for this because students rarely go anywhere without one.

2. Upload the pictures to a Google Drive folder.
It only takes one tap to move photos from a phone phone to a Google Drive folder labeled "Fall foliage." If This Then That has a recipe for doing this automatically from Android phones and from iPhones.

3. After four to six weeks, upload photos to JellyCam or Stop Motion Animator and create your timelapse.
JellyCam is a free video editing program for Windows and Mac users. You can easily adjust the duration of each frame and easily add a soundtrack to your video. Click here for a video about using JellyCam. Stop Motion Animator is a free tool for creating stop motion movies on Chromebooks.

### Slides from ESC-20 Library Resource Roundup

Today I had the pleasure of giving four short presentations at the Texas ESC-20 Library Resource Roundup. It was a great day! Thank you to everyone who came to my presentations. And a special thank you to those who came for multiple presentations. As I always say, the best compliment that I can get is when you have seen me present and you come back for more. Here are the slides from the presentations that I gave today.

### How to Make a Timeline Through Google Sheets

Earlier this week I wrote about Flippity's new timeline creation template for use in Google Sheets. The template lets you create a multimedia timeline by simply entering information into a spreadsheet and then publishing it to the web. There are a couple of quirks to using the template that should be noted before you have a whole class of students use Flippity to make a multimedia timeline. I point out those quirks as part of my tutorial video embedded below.

### Three Apps to Explore the Potential of Augmented Reality

On Friday I am giving a presentation about augmented reality, virtual reality, and mixed reality in education. If you're unsure of the differences between the three, take a look at my explanatory video and slideshow on the topic. As a part of the presentation that I am giving I will be demonstrating a few augmented reality apps that you can use in your classroom. Those apps are Google Expeditions, Plum's Creaturizer, and Metaverse.

Plum's Creaturizer
Plum's Creaturizer from PBS Kids is a free iOS and Android app that lets students create fun cartoon creatures then place them into outdoor settings through the use of augmented reality. The purpose of the app is to have students learn and show how the characteristics of an animal help it thrive in its environment. In the following video I demonstrate how the app works (apologies for the background noise, I recorded this video outside to show how the AR feature works in real settings).

Google Expeditions AR
Google Expeditions is best known as for its virtual reality tours, but it also has an augmented reality component. In late May of this year Google added augmented reality tours to Expeditions. The AR content in Google Expeditions lets students view and manipulate digital content in a physical world context. The new AR content can be used as components in science, math, geography, history, and art lessons. Some examples of the more than 100 AR tours that you'll now find in the app include landforms, the skeletal system, dinosaurs, ancient Egypt, the brain, and the Space Race. And as a good Mainer my favorite of the new AR tours is about lobsters.

To use the AR content available through Google Expeditions you will need to print marker or trigger sheets that students scan with their phones or tablets. Once scanned the AR imagery appears on the screen. (You can actually preview some of the imagery without scanning a marker, but the imagery will not be interactive or 3D). Students don't need to look through a Cardboard viewer in order to see the AR imagery. You can get the Google Expeditions Android app here and the iOS version here.

Metaverse
Metaverse is both an app and an augmented reality game creation tool. The app, available for Android and iOS, lets you find and play augmented reality games. The app includes a large selection of educational games. The game creation aspect of Metaverse lets anyone create his or her own augmented reality game. Since its launch eighteen months ago, teachers have been using it to create AR games for a wide range of topics including geography, math, science, and language arts. Watch the following video to see how you can create an augmented reality game on Metaverse.
