The Map of Mathematics — Infographic

The Map of Mathematics

When are we going to use this?  Why do we learn this?  How much math is really out there?  This interesting map of mathematics was created to show just how wide reaching and diverse the field of mathematics really can be.  From learning to count to simple arithmetic into more advanced areas like calculus and differential geometry to practical applications like statistics, game theory and even economics, this chart has it all.  Make sure to check out the wonderful video explaining it all, linked below.   [VIA]

MyScript Calculator – Intuitive Handwritten Math App

MyScript Calculator

This is my new favorite app!  The MyScript Calculator is a unique tool that allows students to handwrite complex equations and formulas into their iPad or iPhone and obtain instant results.  Not only can this be used to perform simple arithmetic operations, but the MyScript Calculator can also handle more complex operations, including trigonometric functions, logarithms, and certain constant expressions.

From the developer, the full list of supported operators includes:

Basic operations: +, -, x, ÷, +/, 1/x
Misc. Operations: %, √, x!, |x|
Powers/Exponentials:
x, xy , x2
Brackets: ( )
Trigonometry: cos, sin, tan
Inverse trigonometry: acos, asin, atan
Logarithms: ln , log
Constants: π,
, Phi.

One of the only drawbacks of the MyScript Calculator is that while the technology is intuitive, it is not perfect as assessing what students intend as they write.  Therefore, it is important that they try to do so neatly in the app.  Also, variables are not written as they would in a common algebraic expression.  For example, MyScript reads “x” as multiplication instead of a variable.  Simple single variable expressions can be solved but students need to use “?” as that variable, as opposed to letters.

The applications and advantages of this app are enormous, however.  Students who are unable (or unwilling) to use a basic calculator can try MyScript for a more tactile math experience.  This would also be a help to those students who need to solve more complex calculations that would be difficult with pen, paper, and a traditional calculator.  While MyScript will not, and should not, replace more traditional methods of computation and equation solving it is a fantastic tool to have in your belt.

Video of the Day – 3/14/13 (Calculating Pi with Real Pies)

Daily Video — “Calculating Pi with Real Pies”

The gents at Numberphile have outdone themselves again!  Check out this fantastic, fun video where they attempt to calculate the actual value of pi using one of my favorite things — real pies!! 🙂  (Make sure you check out the run-time too, those sneaky buggers!)

Happy Pi Day — Infographic

All You Wanted to Know About Pi

March 14. 3/14. 3.14 Pi Day! Today is the day that the math teachers in my building live for, and there is a full slate of activities planned in all their classes. How much do we really know about pi, however? I know I am still caught in the trap that when I hear the word, all I can think of are delicious circles of Apple or Coconutty goodness — which makes me half right, I suppose! Today’s infographic helps to explain some of the properties of pi, as well as its many applications in mathematics and engineering. [VIA]

A+ Click Math & Logic Problems

A+ Click Math & Logic Problems

A+ Click Math & Logic Problems

If you are in need of some technology and an interactive, customizable component to your math lessons, you might be interested in A+ Click’s Math and Logic Problems.

A+ Click’s problems run the gamut of difficulty and complexity from the 1st to the 12th grades and cover a myriad of other subjects from Arithmetic and Geometry through Everyday Applications, Sports, Logic, and Funny problems.

There are two ways that you could possibly use A+ Click:

  • It could be used as a quick gauge of student’s skills as each grade level allows the student to take 20 questions in their “quiz” and then, if they score high enough, they can advance to the next level – almost as though leveling up in their favorite video game.  They’ll love seeing how far they can get, and you will like seeing the statistics provided by A+ Click that assess the skill areas they are having difficulty in.
  • Alternately, you can pick and choose individual questions from any of the grade levels or subjects on A+ Click.  Use these as pre-made warm up activities or exit tickets.  Instant feedback is provided and the site lends itself to both projectors & white boards or to your chalkboard.

As with any interactive site, A+ Click Math and Logic Problems relies heavily on browser plug-ins – in this case Adobe Flash.  Make sure you test the site on the machine you want to use in school first to check compatibility.

Circles Are Awesome — Interactive Geometry

Circles are Awesome

Just a quick interactive lesson today that would be perfect as a distraction in any class or as a full lesson in a geometry class.  Circles Are Awesome uses the principle, that like a triangle, circles are unique in that they only need three points for you to create one.  In Circles Are Awesome, students can learn how this property works and then play with it themselves to create and manipulate their own circles.

From the front page of Circles Are Awesome, have students first select that they want to “learn about circles”.  A short 10 page flash tutorial will explain the concept behind using three points to create a circle and how this is mathematically possible.  Then once they are finished, allow students to play with circles”.  In this section, they can move and manipulate the three control points to create any size circle they wish.  Have them increase the number of circles created to illustrate the relationship between all the circles that can exist within the parameters of the control points.

Circles Are Awesome also has a print feature that you can use with the students to have them not only create several congruent circles, but then print their creations to work through proofs and calculations to determine the properties of the circles they created as well as areas and volumes.  You could also have them manipulate the points to create symmetrical pairs and then describe the conditions that needed to be met with their control and center points to achieve this.  The possibilities of the Circles Are Awesome manipulation page are literally infinite!
