Ten Best Math Instruction Tools

In his excellent TEDx talk, “Math Class Needs a Makeover”, Dan Meyer affirms some basic truths about math class: 1) anyone can learn to be successful in math, 2) traditional approaches to math instruction have poorly served a large number of our students, and 3) making math instruction practical is the key to making it “stick”.  He never uses the term “UDL” in his talk, but the changes he proposes are all about changing how we represent material, how we express our conclusions, and how we engage with the curriculum – the three principles of Universal Design for Learning.

Here are my ten eleven twelve favorite sites to use to support math instruction.  None of them are procedural guides or electronic worksheets.  They all involve building an environment that the student can manipulate and get immediate feedback on their efforts.  Some of them can be done quickly.  Some take longer.  But, they all make effective use of the “problem-based learning” model.

  1. NLVMhttp://nlvm.usu.edu
    A vast array of math manipulatives, indexed by grade band and by sub-topic (Number & Operations, Algebra, Geometry, Measurement, and Data Analysis & Probability). This is a long-time favorite of mine.  Most of the applications are built on the Java platform, which unfortunately means they will not work on a Chromebook.  If you have a teacher station with a browser that still runs Java, some of the manipulatives work extremely well with an interactive whiteboard.
  2. iSolveIthttp://isolveit.cast.org/home
    CAST provides two iOS apps that keep the goal of developing logic and reasoning skill at the focus, beyond simply providing a right answer.
  3. Interactivatehttp://www.shodor.org/interactivate/
    Interactivate includes the standard fare of manipulative activities and stock lessons, but goes the extra step of providing ideas and material for Class Discussions.  Also has an associated iOS app.
  4. Illuminationshttps://illuminations.nctm.org/
    The National Council on Teaching Mathematics provides this set of manipulatives, titled “Illuminations”.  Searchable by grade band and sub-topic.  Includes Common Core and NCTM standards.
  5. PhET Interactive Simulationshttps://phet.colorado.edu/
    Colorado University provides this set of modern HTML5-based manipulatives.  Math is the basis for some, and is a strong undercurrent for many of the science activities.  Because of the modern platform, these work well on just about any device or screen size.
  6. NRichhttps://nrich.maths.org/students
    Includes printable support materials for class and teachers.  And, it gives you a chance to explain to the class why the word “maths” shows up all over the place!  Don’t get thrown off by the UK terminology, the activities are indexed for US grade levels as well.
  7. SolveMe Math Mobileshttps://solveme.edc.org/
    Without using the words “equation” or “algebra”, this interactive puzzle game provides a great introduction to those concepts, while reinforcing number sense and application of basic operations.
  8. Cargo Bridge from Limex Games – http://limexgames.com/games/cargo_bridge/
    The guy has to push the box home.  But, there’s a chasm in the way!  Build a bridge to support the guy and the box, with the limited supplies you have available.  You’ll never hear the question, “When am I ever gonna need to know about triangles in real life?”
  9. “Full Steam Ahead” gamehttp://www.ssgreatbritain.org/full-steam-ahead
    Math abounds in a set of physics and engineering problems based on the real-life advances designed by Isambard Kingdom Brunel.  As you progress through the early tasks, more types of challenges are unlocked.  Build, Test, Tweak, Repeat.
  10. Math Playgroundhttp://www.mathplayground.com/math_manipulatives.html
    Somewhat limited set of resources, but the ones that are available are very useful.  Geared more for upper elementary.  Should work well with modern browsers.
  11. Desmos Graphing Calculatorhttps://www.desmos.com/
    A graphing calculator for your browser!  Powerful save, overlay, and editing tools.
  12. Geogebrahttps://www.geogebra.org/
    Online graphing calculator, and a host of additional tools for math instruction, including geometry, algebra, calculus, statistics, and more.  Downloadable materials as well as online activities.

The Ten Best Technology Movies of All Time

Some movies rely heavily on some aspect of technology (and its development, and the ramifications when things go awry) to advance their plot.  These are my ten favorite tech films of all time!

10) The Fly (1958) – Teleporters would be awesome, right? What Movie poster for The Fly, 1958.could possibly go wrong? The original 1958 classic does a great job of staying on the edge of “plausible deniability” in scaring the bejabbers out of the viewer! I didn’t think the Jeff Goldblum / Geena Davis remake was terrible.  In some ways, it was definitely better than the original.  For this list, I have to go with the 1958 version because the ending is so much better.  “Help me! Please, help meeee!”

9) WALL-E (2008) – Yes, I have kids.  Yes, I watch Disney movies. Wall-E character Occasionally, I even watch one when the kids aren’t around (Mary Poppins is still one of my all-time favorites).  This one took a movie plot that is generally only reserved for trying to unsettle adult audiences, and made it accessible and fun for all ages.  It still provokes the question of “what would happen if all the people were gone”, but without the cataclysmic darkness that puts most films like this into the “after the kids go to bed” time slot.

8)  Apollo 13 (1995) – When the original mission (landing on the Scene from Apollo 13.moon) of the Apollo 13 crew has to be scrubbed, a new mission takes its place (saving the astronauts’ lives as they return to Earth).  Can you design something to rescue three imperiled astronauts using things like the flight plan cover, duct tape, and socks, before the CO2 levels in the capsule overtake them? How did it actually work?

7) The Terminator (1984) – C’mon.  It’s The Terminator.  Do you really need to know any more?

6) Ferris Bueller’s Day Off (1986) – Why did this make my list?

“I asked for a car. I got a computer. How’s that for being born under a bad sign?”

The whole thing couldn’t have been possible without Ferris using a room full of outrageously geeky (for its time) technology to hack the house intercom system, provide medical sound effects, and even hack into the school computer system to eliminate an overabundance of absences.  All that, and he couldn’t figure out how to make the odometer go backwards on a 1961 Ferrari 250 GT California Spyder?

5) Office Space (1999) – The premise of the central plot element in Office workers ready to destroy the laser printer.this movie makes you think, “Well, yeah, what DOES happen to the fraction of a cent that gets dropped off of all those financial transactions?”  The rest of the movie is built on the positive and negative interactions between the personalities of the characters, but the thoroughly believable idea of siphoning minuscule amounts of money to create a multi-million dollar bank account, and sticking it to the man, practically dares us not to identify with the cubicle dwellers getting screwed at every turn.  And who hasn’t wanted to hand out a little street justice by curb-stomping a laser printer that spouted “PC LOAD LETTER” just once too often?

4) Minority Report (2002) – Smart move, setting this movie just far

Spatial Operating Interface from the movie Minority Report.
Admit it, you want a pair of these gloves.

enough into the future that I can imagine myself being still alive should the world turn into something like this.  A blend of humans with special abilities (“Precogs”) and technology has allowed law enforcement to detect when someone is going to commit a crime.  Using this technology, they preempt the crimes from occurring and arrest the would-be perpetrator just as if they had committed the crime.  We were awed by the “spatial operating environment interface” that John Anderton used when he slipped on the special gloves.  Little did we know that only a few years later, multi-touch surfaces and devices like the Xbox Kinect would make those science fiction morsels become a tasty reality long before 2054!

3) Tron (1982) – We didn’t even know what a “hacker” was in 1982,

I had these when I was a kid. So cool!

but the concept of getting trapped inside a virtual video game world was fertile ground for Disney’s second entry in my list.  See, kids, back in the 80s, we had to go to a mall to a place called an “arcade” to play video games.  And the guy who ran the arcade had the coolest job in the world.  There is a bit of cognitive dissonance that still goes on in my head – I refuse to believe that the Jeff Bridges from this movie is the same Jeff Bridges from any of his other movies.  Nuh-uh, no way, nohow.

Open the pod bay doors, HAL.2) 2001: A Space Odyssey (1968) – Stanley Kubrick just has a way of making “poison ivy” movies.  They get under your skin and itch until you have to scratch it, and it just makes the itch worse.  “I’m afraid I can’t do that, Dave.”

1) WarGames (1983) – Matthew Broderick makes another appearance on my list, this time with the quintessential tech-based

You can’t read it without hearing it in the computer voice, can you?

movie of all time.  When you’re working on a text-based terminal, how do you know what’s “real”, and what’s just a construct of artificial intelligence? I was already a burgeoning computer nerd at the time, having written my own Casino and Horse Racing programs in Applesoft Basic on a VTech Laser 128 during a snowstorm-lengthened winter break from school, and this movie put dreams in my head of one day doing things with a computer that would go beyond my own house. “Shall we play a game?”

Obviously, I’ve chosen several movies that bridge a gap between implementing technology (“can we do it?”) and philosophy (“should we do it?”), which has long provided a foundational element for plots in movies, literature, etc.  What movies did I miss that I should have included?  Which one of these movies doesn’t deserve to be in the list? Go ahead, have at it!
