Education Apps

Quizlet By Quizlet LLC

has a bunch of ways to study facts, including flash cards and audio in 18 languages.  It's free.

Mathway By Bagatrix

is also free, and solves problems for students without helping them understand how to solve them.  It's a very bad thing, I think.

Graphing calculators are so much more powerful than normal calculators, but they cost so much money. Now, we get one for free, so students who can't afford a graphing calculator can use this.

How to make Paper Airplanes By Sergey Burlakov & How to Tie Knots By Sergey Burlakov

These apps introduce students to some hands-on concepts that don't even feel like math.  And, it's free.  I think that these kinds of ideas are awesome for students.  In graduate school, I used to have these long discussions with my roommate about how people are fooled into believing that math is the same as arithmetic.  Anyone who does well in arithmetic in elementary school believes that they are destined to be great at math, and a lot of them wind up being disappointed when they get into high school or beyond.  Anyone who struggled with arithmetic when they were young, on the other hand, believes that they aren't good at math.

There is some relationship between success at math and skill at arithmetic, but we get entirely the wrong idea if we think that's all there is to it.  By introducing students to ideas like tiling, knots, folding paper, etc., I can introduce them to ways to think about math without thinking about arithmetic.
