Happy Pi Day! Mmmm Delicious Pi Edtech Resources


What is Pi Day?

Happy Pi Day! On March 14th (3/14), math nerds all over the world will be celebrating one of the most famous irrational numbers (sorry tau)! I believe this year’s Pi Day is very special because the date (at least the American date) is 3/14/15 which represents the first five digits of pi. Even better this year the date and time, 3/14/15 9:26:53 am, will represent the first ten digits of Pi (3.141592653)! The greek letter π represents pi and it was first used by William Jones in 1706. Its value is usually rounded out to 3.14 for everyday calculations. If I were to write every single digit of pi it would probably take me years upon years to write out. Currently pi clocks in to be about 10 trillion digits!

So what’s so special about the number pi? Well it’s the ratio of a circle’s circumference to its diameter. No matter what the size of a circle may be, this ratio will always remain the same. It will always be equal to about 3.14 or pi! When it comes to measuring the area or volume of geometric shapes, like circles or cylinders, pi makes this calculation much easier!

Here is a great Math Edtech Resource where you can learn more about Pi!



What this Resource Includes: Subjects: Geometry, Algebra
Subjects: Geometry, Algebra, Statistics, and Calculus
Grade Level: 6-12
Audience: Learners, Teachers
Platform: iPhone & iPad, Android, Chrome, Windows

Price: Free
What it does well: Geogebra gives learners the space to freely interact with shapes and learn about their properties. Users can learn through exploration and experimentation. Learners will have a deeper understanding of geometric shapes by creating their own shapes, angles, and graphs. The site also includes a nice library of learning materials and worksheets, which were created by the users. Teachers can also use Geogebra to create their own lessons and easily share them with their students.

All aboard the S.T.E.A.M. Train! Science, Technology, Engineering, Art, & Mathematics Edtech Resources

What is STEAM?

S.T.E.A.M. stands for Science, Technology, Engineering, Art, & Mathematics. It’s STEM education but with the addition of the art subject. STEAM learning can promote creativity, critical thinking, and problem-solving skills. Integrating art concepts like design into STEM subjects can encourage students create innovative projects, products, and solutions.  Although the arts may not get a lot of love in schools, a study showed that when it was integrated in a classroom students were more creative, engaged, and more effective at problem solving than a non-art integrated classroom.

The STEAM Train

In honor of the STEAM learning philosophy every month or so I will share a collection of edtech resources, one for each of the STEAM subjects. Here are a few to get you started:


Bobo Explores Light

What this Resource Includes: Science Reading Material, Interactive Content
Subjects: Physics
Grade Level: 3-6
Audience: Learners
Platform: iPad
Price: $4.99
What it does well: Bobo Explores Light is a great app to introduce young kids to a few concepts of physics. It resembles an interactive e-book with a robot as your guide. Each page cover a different scientific concept. Users can interact with gadgets, lasers and other science instruments in the app and learn by observing reactions from these interactive features. The app also provides reading material about science phenomenon including lasers, lightning, and bio-luminescence.


Code Hunt

What this Resource Includes: Coding Games
Subjects: Programming-Java, C#
Grade Level: 6-12+
Audience: Learners
Platform: Web-based
Price: Free
What it does well: Code Hunt is a programming online game from the Research in Software Engineering group and Connections group at Microsoft Research. As of now it teaches users Java and C# coding. The game consists of many levels where players learn about arithmetic operators, conditional statements, loops, strings, search algorithms and more.


123D Circuits

What this Resource Includes: Breadboard, Schematic and PCB editor, Shop for Electrical Circuit Kits
Subjects: Electrical Engineering
Grade Level: 6-12+
Audience: Learners
Platform: Web-based
Price: Free
What it does well: 123D Circuits is an online circuit breadboard simulator that lets users experiment with digital circuits and share them with an online community. The site also includes a shop where users can purchase conductive pens and various circuit kits. It even includes a basic circuit kit designed for teachers to use in a classroom.



What this Resource Includes: Digital Music Sheets
Subjects: Music Sheet Reading
Grade Level: 3-12+
Audience: Learners
Platform: iPad
Price: Free
What it does well: Chromatik is a music learning app that includes music teaching tools like sheet music, electronic recorders, metronomes, and tuners. The app includes a music sheet library from different genres of music. Users can create their own sheet music and share it on the app. They can also record themselves playing an instrument and then share the audio with the Chromatik community or through social media.


Dragonbox Algebra

What this Resource Includes: Math Games
Subjects: Algebra
Grade Level: 1-6
Audience: Learners
Platform: Android, iPad & iPhone
Price: $4.99 & $7.99
What it does well: Dragonbox teaches players algebra without any numerical values. There are two versions of the game with 12+ being more difficult than 5+. It has game mechanics that makes it addicting, similar to other mobile games like Angry Birds. Each level becomes increasingly difficult to keep challenging the player. A score of up to three stars can be earned for each level. The less moves a player made to complete the level, the higher the score. Dragonbox earns bonus points for providing teacher resources on their website. It includes manuals, worksheets, and Common Core standards alignment.

Does PhotoMath have any learning potential?

PhotoMath is a new mobile app that allows users to take a picture of a math equation on their phone and instantly receive an answer. As of now the app can only read printed equations. So it’ll be most useful when students encounter a tricky math equation on a textbook. Also the app can solve only arithmetic, fractions, decimals, powers, roots, and linear equations a well as functions like log, exp, sin, cos. This means that it won’t be much help if students are faced with a word problem.

At first the app sounded like a great way to cheat on Math homework. After a little digging around on the PhotoMath homepage, I’ve learned that it does more than pop out an answer. The app also provides a step by step solution to the equation. But does this makes PhotoMath a learning app? I think it does have the potential to become one. One idea to increase its learning potential can be if the app provides the users with similar or more difficult problems after viewing a solutions. This is so that they can use what they’ve learned from the step by step solution and apply it to more advanced equations. This can be a good way to reflect on the original problem for deeper learning.

After reading the PhotoMath blog it was clear to me that they didn’t create the app for cheating. I’m really interested in seeing if this app will be able to solve more advance math concepts like integrals and derivatives. What do math teachers think about the learning potential of PhotoMath? Sound off in the comments section below!

Until next time keep calculating everyone!
