I was in the main office the other day and I heard a chemistry teacher singing the praises of his Apple TV. When reviewing homework (lots of math in chemistry), he asks students to mirror their iPads. If a student has a question, he asks that student to mirror her iPad so the class can look at her work. **They work together** to find the mistake and correct the problem. Then they move on to the next one. He said the students love sharing their work with the class and helping each other find mistakes … **it’s like a puzzle **(for the whole class to work on together).

# Multi-tasking Struggles

Have you ever tried to watch a video on YouTube and take notes on your iPad at the same time? I often ask my students to watch short videos on YouTube for flipped lessons (have you heard of it? I’ve had great success incorporating it into my Algebra 1 class). But my students take their notes in Notability on their iPads. So in order to complete this assignment, they have to **use two devices** (one to watch the video, one to take notes in Notability).

When Lia wrote about the Downside to Digital Textbooks, my Algebra 1 students were using paper notebooks. Now that they are using Notability and have an iPad based textbook, **we’re running into the same problem** when they do their homework.

My students seem content enough to screenshot the problems and insert the image into Notability. Others use the four-finger swipe/gesture to go back and forth between apps. I don’t really like either of these solutions. They seem more like **temporary work-arounds** rather than true solutions. I’m coming to the conclusion that the only true solution will be when the “textbook” provides a work space for students to complete problems.

# Cold Season = Increased Absences

It’s cold season in Massachusetts (I’m even writing this while surrounded by cough drops and tissues). Cold season means my students miss class more often and come back to school overwhelmed by make-up work.

In our 1:1 environment, I write out my examples in Notability and my students take their notes in Notability too. When a student is absent, he/she typically asks a classmate to share the notes from class before coming back to school. While this doesn’t make up for the missed class, when absent students come to see me the next, they have already seen the notes and are prepared to ask questions other than the dreaded “**did I miss anything?**”

Note: Students typically “share” their notes with each other by sending their Notability file via email to another student.

# Desmos Graphing App

Graphing calculators are good, but the Graphing Calculator app by Desmos is better. Graphing calculators are expensive. *(The Desmos app is free).* Graphing calculators require several clicks to change the ‘window’ of a graph. *(The Desmos app is interactive and I can zoom in with my fingers). Graphing calculators can be finicky when entering complicated equations. (The Desmos app points out your error). *

I could go on an on about why I think Desmos makes a better graphing calculator for my students, but instead I’ll tell you about my Trigonometry students.

We are headed towards proving trigonometric identities, but before start simplifying them by had, I had them graph pairs of equations whose **equations looked very different **but** graphs were identical**.

Imagine their surprise when only one graph showed up! Several were concerned that they had done something wrong, but au contraire, they are equivalent equations! We had a lot of fun entering pairs of equations and deciding whether or not they were equivalent.

My students have started calling these trigonometric identities “same, same, but different” because they look the same on the graph, but they have different forms when written.

When I did this same activity last year with graphing calculators, it took forever to enter the equations and then find their mistakes if they forgot parentheses. **The Desmos app saved us a lot of time** and therefore allowed us to try lots of different pairs of equations.

Desmos also has a web based calculator that is just as fun!

# Geometry Proofs: So Many Ways!

I teach Geometry. My students struggle with the idea that there are lots of different ways to prove something. What they really hate is that there isn’t *one right answer. *I on the other hand get the most frustrated when a student is looking at a proof I have projected saying, **“I did something different … am I wrong?”**

Prior to our 1:1 iPad environment, I would have said, “well let me come take a look” or “how about you write it on the board and we’ll look at it?” Oh the time I wasted waiting for kids to write on the board … oh the time I wasted looking at one kid’s work while the rest of the class stared off into the distance.

Enter Apple TV and students doing their homework in Notability on their iPads. Now I say, “could you mirror your iPad and we’ll look at your proof** together as a class**?” Within seconds, the whole class is looking at an alternative method of proving something. Sometimes it’s right. Sometimes it needs to be tweaked. Other times, it’s way off. But regardless, we get to look at several different proofs for each problem and still have class time left to do something else!

# Self Grading Homework

When my students are working on a particularly difficult topic, I like to know if they’re on the right track. If I don’t get questions via email or see students in my room the next morning, I begin class without knowing where my students stand with yesterday’s material. **This isn’t exactly ideal.** (I realize I could scrap the idea of homework, but that’s not where I’m headed.)

Instead, I have my students enter the answers to their homework problems into a Google Form. They’re not submitting all of their work, so it doesn’t take much for me to scan through their answers and quickly get an idea of whether each student is on the right track.

I tried this for the first time last week when my trigonometry students. I created a Google Form asking for identifying information (first and last name, email address, and class period) and answers to each of the five homework questions. Since my students do their homework in Notability on their iPads, it was easy for them to quickly enter their answers and submit the form when the were finished with their homework:

I checked in on the responses a few times, emailed students who seemed to be way off track and offered some hints based on which problems were wrong.

Then, before class, I used **Flubaroo**, a script in Google Forms, to “grade” the homework and email students their grade (out of 5) as well as the answer key. Below is the summary of the grades. [Note: I did not use this grade, but rather, I gave full credit to students for completing the assignment.]

Instead of starting class by asking what questions my students had, I was able to **target the one question that most students struggled with. **Another nice thing about using forms to collect homework responses is the ability to **project all of the responses** at the beginning of the class period. When I ask an open-ended question, I like for my students to see all of the different responses and discuss which ones are better explanations. Thank you Google!

# Google It!

How many times a day do you turn to Google Search for an answer, clarification, or more information? I do it all the time and even had my whole Algebra 1 class hunting for information on the Hope Diamond today! It all started when I gave my students this information and asked them to come up with the question:

*In 1673, the Hope Diamond decreased in size by about 45 carats, resulting in a 67 carat diamond. *

I thought we were solving a simple word problem but I quickly realized that they didn’t even know what the word problem was about. While some of the students asked what the original weight of the diamond was, many of them were asking what happened in 1673?! Others were asking what the Hope Diamond is. One student asked what a carat meant. With 15 minutes left in the class, we quickly solved for the original weight of the diamond, and then turned to Google to find the answers to all of their other questions.

I created a Google Document, shared it with the class, and had each student editing the document from his/her iPad. They were reading articles from the Smithsonian and PBS (in math class!). They were finding pictures and posting links in our Google Doc. Some students could hardly contain their excitement to learn about the curse that haunts those who touch the Hope Diamond!

I surprised myself today with how quickly I was able to turn to our 1:1 program as a way to engage my students with something I had not planned ahead. **But really, what’s the point in solving a problem about the Hope Diamond if you don’t get to learn about the Hope Diamond? **
