Using the Post It Plus App in Math Class

Every Tuesday at my school, we have Tech Tuesday.  Every teacher has to go to a tech session where the tech department talks to us about a new app that we should be familiar with.  So far this year, we've learned about Explain Everything, Socrative, iMovie, and Book Creator, just to name a few.

This last week, we were supposed to investigate an app that we were interested in and show how we could use it in class.  I seriously had NO ideas until I happened to come across this Post It Plus app [FREE!].  (Post It Plus App Info)  A lightbulb went off!  I can use this app in class!  As a bonus, I can even design things for my girls using this app :)

The general idea is to be able to take a picture of post it notes and be able to transport them and organize them.  So, if you are in a meeting or just have a big bunch of post it notes on your wall, you can take a picture of them in the app and THEN…. wait for it… move them around in the app!

How am I envisioning using this in class?  …for matching or ordering activities.  For example, I was thinking of using it in my geometry class for students to match area formulas to shapes.  In calculus, I was thinking of using it for students to match trig functions to their derivatives.  For my girls, I was thinking of having them put the numbers from 1 - 10 in order.

So, the first step is to write some things on post it notes - who doesn't have a million of those laying around?  Different colors?  Yes!

I decided to try this using geometry formulas.  So, I wrote some of the different formulas and their corresponding shapes on different color post-it notes that I had laying around.  Here is a picture of the post it notes on the floor of my kitchen.

Here is a picture after I imported them into the Post It Notes App.

I think that the app recognizes the post its very well!  Note that you can only use square post its - according to the directions in the app, the app will not recognize other post it shapes - they will be made into square post its.  I used black marker to write on the post its…I wonder how regular pen or pencil would work?  I will have to try that.

The next step is to see if I can export this post it board to another iPad.  I successfully shared this "board" to a student's iPad by Air Drop.  Their iPad opened it automatically, right into their app.  (Students had to have the app too so that they can move the post its around - no problem - did I mention the app is FREE :)

Finally, I want to see how I can grade this.  I want to see how the students can send it back to me.

My students matched up the formulas…

and then they choose to export the file in pdf format back to me through email.

My only problem was, how do I know whose is whose?  I wanted them to somehow put their name on it, so everyone could get credit for their own work.  I believe that the students could submit this through a classroom management system such as Showbie also.  But, we didn't try that yet.  I don't know about you, but I hate having the students submit things through email…I hate having all of those emails to sift through.  Still working on that one, but I call use the Post It Plus app a success!

Have a great weekend.

Similar Triangles Worksheet with QR Codes - FREE!

In the spirit of sharing more about how I use QR Codes in the classroom, I have posted a Freebie worksheet in my TPT store which allows students to practice finding missing sides in similar triangles.

This worksheet has 8 problems and allows students to get the answer immediately by scanning the QR code with their smart device.

What is different about just checking the answer with the teacher or in the back of the book?? Nothing really, except using technology in class is fun :)

If you download this worksheet and give it a try, let me know how it works - I would certainly appreciate your feedback.

Have a great day!

Fractions Scavenger Hunt

My sister is now teaching 4th grade.  She's a first year teacher, so I thought I might help her out with some math lessons and games.

I am pretty happy with this first one - it is a scavenger hunt that involves adding fractions.  Students must add fractions with like denominators and then be sure that their answer is in simplest mixed number format.

In this set there are 8 cards.  Students start anywhere and then solve the problem on their card.  They then hunt around the room until they find the answer to that card.  They then solve that problem and then hunt to find the answer…play continues until they end where they started.

Fun practice that allows the students to move around and practice at the same time!

If you're interested, here is a link to the hunt in my TPT store:

Calculus - Teaching Definite Integrals

It's the start of the second semester and that means the beginning of integrals in Calculus AB!

Don't start the second semester doing this:

If the beginning of second semester means as much to do at your school as it does at mine, maybe you could use a little help with some new materials that you don't have to create yourself! Check out the round up of ideas below.

1)  First up, I made a couple of new pages this week that worked pretty well with my Calculus class.  We worked on the concept of what a definite integral is, and then found the definite integral by using Geometry and Integral rules.  Here is a look at one of them:

If you're interested…here is a link to the full product in my TPT store:

Finding Definite Integrals with Geometry

2)  Next up...some task cards from Joan Kessler that could be used to review with students once you have introduced the concept of finding the area between the curve and the x-axis.

Task Cards for Definite Integrals

3)  This looks fun - try this Calculus Cook Book Activity from The Math Lab.

Use definite integrals to transfer all the numbers in a recipe into a calculus problem.  Fun!

3)  Finally - do you need an entire lesson for teaching Riemann Sums and Definite Integrals?  Try this from Jean Adams!

Riemann Sums and Definite Integrals

Have a great week!

Using QR Codes to Play Tic-Tac-Toe

It is the second day of no school here in Illinois.  It is -30˚ wind chill and many schools cancelled today.

So, I thought I would share one way that you could use QR Codes in the classroom.

(Since my kids are home today they are demonstrating for you :)

This particular activity is good for a math center or for students to play in partners.  Not every student participating needs an electronic device because of the way the game is played.  If you are going to use this as a math center, I recommend laminating the game board and the X's and O's.  That way you can use the same board over and over.  If you're really ambitious maybe you could put a little square of velcro on the back of the X's and O's and in each corner of the game board to keep them in place.

This game follows the traditional tic-tac-toe rules.  Students choose a square - each square has a problem in it.  The student works the problem and then uses his or her electronic device to scan the QR Code.  The QR Codes leads the student to text that will show the correct answer.  If they get the answer correct, they get the square and place an X or O on the square.  If they get the answer incorrect, the other player gets the square.

[CAUTION:  Students must be sure they are scanning the correct QR Code.  It's easy to do - they just have to be careful :) ]

Here is an example of my Freebie of this activity - Solving Systems of Equations.

If you'd like to try this out, head on over to my TPT store to download it:
