TinyScan – PDF Scanner App for Smartphones and iPad

IMG_6195I have been using an amazing app that I really don’t know how I lived without called TinyScan.  Holy mac, this app is a teachers dream!  There is a free version which I tried first.  But, I quickly upgraded to the premium version for $4.99.

With TinyScan you take a picture of something with your phone (for me, it is usually the worked out solutions to homework), take a picture of the page, then TinyScan beautifully turns it into a crisp and clear pdf file.  You can edit, crop, and rotate the file.  You can make it black and white or color and darken or lighten the ink.  You can take pictures of several pages in one file (you may have to have the premium version for batch scanning documents into one file).  Once you have edited your pdf, you can email, AirPrint or fax the pdf’s with one click.  The very best part is that you can instantly upload the pdf to your Google Drive from within the app!  You can also set the app to instantly upload to Google Drive (or other services).  To do this, go to settings and choose Auto Upload, and you can choose from Google Drive, Dropbox, Evernote, Box or OneDrive.  It’s so easy!

The best way that I use it is by uploading the files to my Google Drive.  I created a shared student folder on Google Drive, so as soon as I finish the key I can take a picture of it and upload it to the student file so that my students have immediate access.  I also take a quick picture of all of my test keys and keep them in the same folder as the original in case I lose the key.  I love this app.

Glenn showed me a couple of different scanning apps at TMC15.  His apps were able to rotate a picture automatically if you took it crooked.  However, he could not automatically upload to Google Drive.  So if you look at a different scan app, make sure you can seamlessly upload to Google Drive if that is important to you.

Fill Out This Form to Connect With Other Math Teachers On Kahoot!

There are thousands of public Kahoots! made by teachers to chose from.  Kahoot! has a search feature that allows you to search by title, subject, tag, or username.  You can also share a Kahoot! that you have made with another teacher if you know their username.

Since my Kahoot! post, I have found that many math teachers that I know also use Kahoot! and are using it in ways that I have not even thought of.  For instance, Laura Wheeler uses Kahoot! a few times a week as a warm up for a fun way to do spiraling reviews.  I would love to easily find and see her reviews, since we both teach high school math.

Then, as is often the case, an amazing idea was born on Twitter.  Wouldn’t it be GREAT if we knew our math teacher friends Kahoot! user names?  Then, we could search and share with teachers that we know.  Additionally, if teachers would tag the Kahoots! they use with MTBoS, we could also search that way.

Sharing your Kahoot!

So, please fill out this form if you are interested in easily sharing the Kahoots! that you create and use with other math teachers.  I asked for the subjects you teach so that other teachers can more easily find teachers that have similar needs.  And don’t worry if you don’t make your own Kahoots!  I rarely make Kahoots! from scratch.  But, I do go through each Kahoot! I use carefully, and often edit them, so other teachers would probably benefit from the Kahoots! that I use.  If you are not already using Kahoot!, you need to sign up for a free Kahoot! account here to get your username.

Here are the results: Google Form of MTBoS Kahoot! user names.

Once you finish the form, you will be directed to a Google Form of MTBoS Kahoot! user names.

How to Search and Add Tags in Kahoot!

Also, to search by tag, you can’t just enter mtbos.  You have to type in doc.tags:mtbos.

You Have To Try Kahoot! For Engagement

Moving from middle school to high school this year was an enthusiasm culture shock. For example, in middle school, I had to use Popsicle sticks to limit student participation in class. Many middle school students wanted to answer every question, and I wanted everyone to have a chance to participate.  In high school, I had to use Popsicle sticks in order to encourage student participation. Silence can be deafening, especially at the beginning of the year and always on Mondays.

I do not prefer a silent classroom on a daily basis. I  also prefer that my students talk more than me. So, since my move to high school, I have been endlessly searching for activities that engaged everyone WHILE they were doing math. I tried games, stations, trasketball, speed dating, group work on big white boards, gallery walks, tinker toys, conic cards, Nearpod, Plickers, CANDY and just about anything else you can think of this year to get high school kids ENGAGED and EXCITED (about math work).  While they have liked many of my crazy activities this year, they did not love anything until Kahoot!

Playing Kahoot is the most fun I have had in my classroom in AGES.  Kahoot! is an online multiple choice game where students play against their classmates. I project the questions from my computer, and they select from four choices on their device. Students can use iPhones, iPads, or a computer. Students can also work together and share devices if they do not have enough individual devices. They do not see the question on their device, only the answer choice. As students answer a visual timer counts down and the number of students that have answered pop up on the overhead screen.  To increase the excitement, you can also chose to play KaHoots jeopardy sounding music.

Students get points for getting the correct answer, and even more points if they answer the question more quickly than their classmates. The top 5 students are listed on a “Leaderboard” after each question to keep the competition HOT.

The kids love playing Kahoot! They love playing it so much that I often have my students that aren’t even in the current period join my class during their study hall periods!  Students in class have tweeted and texted out the game code. I even noticed a kid playing through the glass window of my door one day.  Of course I took a picture.


Other than all of the fun for the kids, the best part for ME is that I NEVER HAVE TO MAKE MY OWN KAHOOT.  There are thousands of Kahoots! already made by excellent math teachers everywhere. This is KEY when you have a new planning or are simply overwhelmed. You just type in your topic and then can chose from dozens of premade Kahoots! on just about any topic, including Calculus!

The biggest downside to Kahoot is that the kids want to play it all of the time and beg me daily to play it.

Suggestions for fun and productive Kahooting:

  1. Don’t make your own Kahoot at first. In fact, I may never make my own. There are so many to borrow from!  Once you duplicate a Kahoot, it is easy to edit.
  2. When playing Kahoot, 6 – 10 questions is best. Some kids get discouraged and give up if they fall too behind in the scores. So, instead if playing one KaHoot game with 20 questions, play two 10 question Kahoots! You will have two winners and thus more opportunities to get everyone engaged.
  3. I use Kahoot! as a pretest, for a quick check of their understanding of terms. and as practice problems for more rote  or basic topics. The max time students have to answer a question is 120 seconds so KaHoot is not for problems that take a longer time to solve.
  4. Let them make up silly names. I play Kahoot! so they can have fun while doing math. And making up silly names is really a big part of this fun.


You can also embed YouTube videos into KaHoot. I videoed the kids one day and posted it to YouTube, then added it to their next KaHoot game. The next time we played, their video was what played while they were signing in. They loved it. 

Watch the action here. 

I have just learned about a Ghost Mode in KaHoot but haven’t had a chance to try it yet. Cathy Yeneka blogged about Ghost Mode. I can’t wait to try it in the fall!

Plickers aka “Can We Do This All Period?”

If you want 100% of your students engaged and asking you to do an activity, you need to try Plickers.

photoThe amazing Pam Wilson introduced us to them at Twitter Math Camp.  We were ALL amazed and impressed!

A Plicker is a “paper clicker” with a bar code that the students hold up and then you scan with any smartphone or iPad.  Only one device needed, no batteries required!  The students can pick A, B, C, D or True/False.  The data immediately shows up on your phone AND on their website as a bar graph.  I assigned my students a number, so I can even see who missed the question as I am scanning the room.

From your computer, you can project their responses onto your overhead.  It only shows the correct responses in the “Live View”.

Screen Shot 2014-10-04 at 1.08.27 PM

It also stores the data on their website so you have a record of correct and incorrect answers.  I know you think that I must be lying, but I am not.  These things are AMAZING.

Screen Shot 2014-10-04 at 1.08.13 PM

I decided to affix my students Plickers to the back of their INB with clear contact paper.  That way, they should always have them handy during class, and hopefully they won’t get destroyed!  I oriented them all differently (either A, B, C, or D facing up) on their notebooks so they couldn’t see how other students were holding up their notebooks to get a hint.  It’s so much fun for the students and for me!

I have been using it as a warm-up, to asses prior knowledge or expose them to a new topic that we will begin that day.  I think it would also be a great “Pre-Assessment” or “Exit Ticket” tool.

You can see below how other teachers are using them in class as well.  If you have an idea about how Plickers could be used, please put it in the comments.  Also, if you have blogged about Plickers, please post your link in the comments so that we can all get great new ideas!

Paper Airplanes for Measures of Central Tendencies

IMG_6886I got this amazing idea from Bruno Reddy, @MrReddyMaths.  Go and read his post here. I love his discussion about mean and deciding who should win!  When I saw his post I knew it would be fun.  I planned on using the data to calculate mean, median, and mode.  However, I did not realize how much mileage I would get out of this one activity!  I pretty much teach the entire data chapter using just the data from this one activity.

I have my students watch the “How to Make a Paper Airplane” video and give them the template.  I do not give them any instructions and do not allow them to help each other.  Following directions is always a skill I am trying to teach 6th graders.

After we make the airplanes, we get to fly them!  Of course, I make it a competition. And of course, I video it!

Everyone gets a partner, to help with measuring, and three attempts at the best flight!  Student’s whose planes fly backward get to record NEGATIVE flights.  All three flights are recorded and then entered into a Google Form.  For homework that night, they had to find the mean of their three flights.

Screen Shot 2014-03-23 at 6.55.00 PM

Line Plots and Scale:

I have students make a line plot out of all three entries.  This year, I only had 21 students, so this is 63 entries.  This is a great time to talk about scale.   I have them record their distances in inches, but then they quickly realize that it is a much better idea to make the line plot using feet.  We find the mean, median, and mode of our data using our line plot.

IMG_6762

Range:

Range is one of my favorites here, especially with the inclusion of the negative flights.  This year, our flights ranged from about -300″ to 600″.  Predictably, almost all students told me that the range was 300″.  Students love plugging values into formulas incorrectly.  To help correct this misunderstanding, I had my -300″ flight student and my 600″ flight student come to the front of the room.  I stood at the starting point (the edge of the blacktop for us, also known as 0) and had them stand where their respective planes had landed.  Students immediately not only saw that 300″ was way off, but they saw why.  This was a wonderful opportunity to show them that 600 – (-300) was indeed 900″, not 300″.  My analogy to help deepen understanding was, “You leave from Charlotte to fly to New York, but you have a layover in Atlanta first”!  Nothing is ever better than visual learning and real life examples.

Box Plots:

The next day we learned about box plots.  I project the line plot of our flight data and as a class we make it into a box plot.  They loved seeing that a box plot can helpfully catagorize  their data.  Outliers are visual here, as well as where 50% of their flights landed.  Next year I am going to take a picture of their airplanes laying on the blacktop to back this statistic up visually.

IMG_6761

I also had the students create a box plot of their mean flight data.  They wrote their mean flight length (in feet) on a sheet of 8×11.5 paper.  Then, they organized themselves into a human box and whiskers plot.  The students who were the lower and upper extremes, Q1, Q3, and median all held index cards with the name on them.  We also decided who was in our interquartile range.

Histograms:

The line plot looks very much like a bar graph.  After a very brief explanation about histograms, we turn our line graph into a histogram.  The students love seeing their data grouped and of course ask why we didn’t do this in the FIRST place instead of making the tedious line plot.  It’s all for the sake of learning.  (Insert evil teacher smile.)

Google Doc Data:

I shared the data with the students and we then all made bar graphs and histograms on Google Spreadsheets.  The students like the histograms better as it condensed the data into groups.  They also learned how to sort the data and find the mean using a formula.  Again, they love finding the mean using spreadsheet formulas, find it less “mean” than calculating it by hand, and call me a “mean” teacher for not showing them this in the first place!  Practice makes perfect.

Video Tutorial Project – A Student Favorite

Lights, camera, action!

Screen Shot 2014-01-13 at 9.11.50 PM

Every now and then I have my students watch an explanation (teaching) video online.  I sometimes do this as a review when I’m beginning a topic that they have studied before.  They always hate it.  They always complain.  So, I rarely assign them teaching videos to watch.  They really hated the last one I assigned.  Their complaining gave me the idea to have THEM make their own teaching videos – and to do it better!

The Video Tutorial Project took a week of class time (and that included watching everyone’s videos one day in class).  However, I did not give them a review day or a test for this unit, so it was only about 3 extra days.  In their written reflections, it was clear that my students LOVED this project.  And, their videos were impressive.  They were creative in their presentations and even added transitions, music, and even special effects.  My favorite video was a take off of Vi Hart’s videos.  There is no way I could have made a video this good, ever!

Screen Shot 2014-01-13 at 9.10.03 PM

I partnered the students into groups of 2, and let them pick their topic from our current unit.  They had to state and define their topic, then show three clearly worked out examples, increasing in level of difficulty with each example.  They could make the video anyway they wanted.  They all had to upload their video to YouTube.

I created a project planning Google document for them to follow, and distributed it using Doctopus.  I had them create the three examples problems for homework one evening and submit them on a GDoc form.  That way, I could check to make sure their examples were sufficient.  In class the next day, they made any necessary corrections and planned their video.  They had the next three days to record and edit their video (if they chose to edit it).  I gave no other homework this week so that students would have time to work at home on it if needed.

Watch all of their Video Tutorials Here

This project was worth the time invested and I will definitely do it again.  The students loved it (see their responses below).  We had a few challenges that I would like to address before assigning this again.  One was finding quiet places to record on campus (it was freezing that week so it was not very comfortable outside).  Another challenge was the partner issue.  Students could only work together at school because this was a partner project.  Also, the video editing (if they use iMovie) always falls on the shoulders of one of the partners, which I don’t like.  I have thought about having each student make their own video tutorial, but they have so much more fun working together.  Also, in their reflections all of my students but TWO would rather work with a partner.  They also would have liked more time, but they always tell me that.  They would work on a project for a month if I let them.  They are awesome.

Student Thoughts:  What did you like the BEST about the project?
