Keeping It Shockingly Simple – why these apps are amazing
Mindy, Boo, and Garron explained the thinking behind these two apps. Since algebraic reasoning is one of the best indicators of future success in college, and since Algebra is often a defining moment in a student’s math career, they decided to create two apps to address the processes of the reasoning with built in Universal Design for Learning (UDL) supports. Given that “5% of the goal of math instruction is content, and 95% is reasoning,” CAST created two apps to encourage problem solving and persistence.
MathSquared is a game that combines KenKen and Sudoko. Students solve increasingly complex, numeric puzzles. “MathSquared puzzles are grid-based puzzles that use the basic math operations of addition, subtraction, multiplication, and division and require logic and problem-solving skills.” Initially, I questioned what I would have students DO beyond play a game. However, what if….
Students took a screen capture of a blank board at the culmination of a level, imported it into a screencasting app such as ExplainEverything or Educreations, and then recorded their problem solving process to demonstrate their thinking.
One student took a picture of another working on a problem, and then used Fotobabble to record a “play by play” of their classmate’s problem solving to then offer recommendations later.
Students collaborated on an ExplainEverything project where they compared and contrasted problem solving strategies and then determined who used the most effective approach.
MathScaled offers a different set of challenges. Students solve balanced equation challenges without numbers. The CAST researchers recognized that some students’ aversion to math is rooted in their “fear of numbers.” With MathScaled, shapes have relative weights and students work through puzzles in order to create balance. Chris Harrow (@Chris_Harrow) and Paul Salomon (@lostinrecursion) recently blogged about shifting students thinking about balance. Not only does this app support that challenge, but it could also…
Provide a visual representation for complex equation balancing in both Algebra and Chemistry (imagine teaching the concept of atomic weight with shapes)
Provide a visual representation for history/social studies teachers to illustrate the complexity of “the balance of power.” What if students created a series of math equations to tell a story about historical or political events!
Again, the beauty of these apps is also in how they can be incorporated into other apps through screen captures. In fact, a student could develop a series of math stories that include screen captures brought into Book Creator. Students could include typed narrations as well as audio recording of their problem solving.
I don’t often get this excited about content-specific apps. However, these two are definitely worth mentioning – particularly because of the simplicity! I definitely had a “no duh” moment as it is now feels so obvious about how these simple tools could lead to amazingly complex thinking.
