Let’s Brainstorm!

We are getting ready to present MoebiusNoodles (the book, the site, and the concept) at a brick-and-mortar showcase on June 2. And we need your help brainstorming ideas for our table.

This year we decided to make Grids our theme. So our entire display will be about grids in math, science, life, universe and everything.

Right away we knew we wanted people who stopped by our table to walk away not just with our cards and basic information about Moebius Noodles, but with a tangible mathematical “thing” (a toy or a craft) that they could make themselves in just a couple of minutes. Another important idea is to show the connection between math and everyday life, especially outside of science and engineering.

Our space at the showcase will be pretty small, 4 linear feet or so. So we have to be mindful of that (of course, we can get creative and use the space under the display table, creating some kind of hide-away grid cave, hmmm). Finally, we’d like to stay low-tech and allow visitors to our display (both kids and adults) to touch, try and explore everything they see.

Some ideas we thought about include:

  • Images of grids in art (beautiful), in engineering (i.e. map of Manhattan – a grid that, due to its scale, is not easily noticed by children), and in everyday life (household experiences or items).
  • Grid gamesChocolate Fix by ThinkFun, Battleships, one or two of our own grid games, including Multiplication Towers and Make Your Own Grid activity.
  • Examples of how a grid can be added to a non-grid game or activity and how that creates a different dynamics and introduces important math concepts (as in the photo above when we used a chess board in the “drive around town” pretend game)
  • And somewhere there we’d like to have matryoshka dolls and a Star Wars alignment chart too!

What do you think? What would you suggest we add or remove? If you have activities and games that you created or played with your children that use grids, do let us know. If you have a post on your blog about grid math, post a link in the comments. And if you want to share images of grids, do post a link in the comments.

Rube Thursday

Happy Rube Thursday, a day to celebrate Rube Goldberg machines, the over-engineered contraptions that perform a very simple task.

Did Hogwash inspire you to think up or build crazy contraptions? Here’s another book we recently found, Lights Out by Arthur Geisert. This story is about a little piggy who doesn’t want to sleep in the dark. So he comes up with a plan and builds a very complicated machine that turns the lights back on.

As we talked through this book (there is no text other than on the first page), several interesting questions emerged:

  • Before building his machine, the little piggy drew blueprints and schematics. Why?
  • Do all the parts really work? What would had happened if a curious squirrel picked up one of the pieces and put it down in a different spot? What if the strong gust of wind blew? What if an elephant stomped in the yard?
  • The machine takes so long to produce the result (turn the lights on), that the little piggy falls asleep. What can the piggy do differently?
  • If you were to build a machine, what would it do?
Have you read this book? What do you think about it?

Silly Robot Math

Robots are cool! Just ask any 5-year old (I just did a quick survey of 3 5-year olds and they confirmed it). So let’s play a game that is all about robots, math and silliness.

httpv://www.youtube.com/watch?v=nQtwV0Atzdc

Objectifying people is dangerous, but math entities – operations, functions, algorithms – love to be objectified! “Function machine” metaphor helps kids to see actions as objects or things. This allows kids to progress to the next level: that is, to perform math actions on functions. When functions are objects, kids can act on them: sort, improve, analyze, compose, reverse, loop and so on.

Algorithm is a very curious thing indeed: it’s an objectified sequence of many action, or a Rube Goldberg machine composed of many functions. The usual developmental wisdom is that kids can deal with algorithms with as many steps as their age, for example, a two-year-old can (1) take socks (2) from top drawer but forgets to (3) put them on. However, repeated, fun, meaningful algorithms kids care about work well at earlier ages.

Algorithm is one of the BIG Concepts that children can learn in the Silly Robot game. Other BIG Concepts include

  • Command
  • Function
  • Loop
  • Cycle

So let’s play! Here’s HOW

“Silly robot” turns familiar, everyday task into funny and quirky “Wonderland” games. Choose a simple task, such as filling a glass with water, or putting on shoes. “The silly robot” should be someone who knows the game well. Robots only understand simple, one-step commands, such as “move forward” or “pick up the glass.” They make silly noises if the command is wrong or they can’t do it.

The robot is trying as hard as he can to mess up the task without actually disobeying directions. For example, kids say, “Put the shoe on” and the robot puts it on his head. Kids say, “Put the glass down” and the robot does, except the glass is sideways and all the water spills out! The goal for the robot is to find funny loopholes, and the goal for the team is to give commands without loopholes. Only the robot (the game leader) needs to know this at first – kids discover how the system works! Then they want to play the role of silly robots – analyzing actions as they try to mess up on purpose.

Reusing and improving algorithms is a huge value of mathematicians. Another value is the precision of language and action. One way to be a good “silly robot” is to take commands literally, which helps kids to pay attention to details of actions and their descriptions. The task of playing the robot is difficult, because the robot needs to be slightly annoying, for laughs, but not too annoying.

Infants – Use “mix-up” gags about routine tasks. I think every parent of a baby I know has at least one photo with underpants on the head, done for the baby’s amusement. Tell the baby the dog goes “Meow” and point at the belly button after asking, “Where is the baby’s nose?”

Toddlers – Even before kids are verbal, they use gestures to tell parents what to do and what they want. You can play silly robot games around these commands. Just make sure to laugh with the kid, not at the kid.

Older Children – Progress to more complex tasks and those that involve repetition, such as cutting several tomatoes for a salad, or decorating a room with several pictures. This promotes reuse of algorithms and their parts (cycles or loops). Use computer algorithms.

Other ways to explore algorithms are

  • Story ideas: A storyboard is an algorithm for a movie or a game. Look at favorite books, movies, games, jokes to analyze their algorithms and their parts, such as plots or motifs. For example, knock-knock jokes and “Why did the chicken cross the road?” jokes have distinctive algorithms. Fairy tales and stand-up gags often feature two repetitions and the third action breaking the pattern, for example, “Three little pigs” or “Three billy goats gruff.” Check out this huge depository of story algorithms.
  • Show kids computer tools for capturing algorithms, such as concept mapping or diagramming software.
  • Play “Silly Robot” with math computations. How many mistakes can you make in one problem? Making mistakes on purpose is hugely therapeutic!
  • The game can help with the annoying, persistent issue: kids not remembering some steps in everyday tasks, such as putting lids back on food. After playing for a while, the algorithms are not only laughed at, but also debugged, and everybody is in a better mood.
  • The clearest, easiest programming software, accessible even to toddlers (with parents helping) is Scratch from MIT. It presents steps in algorithms as Lego pieces you put together.

Rube Thursday

Happy Rube Thursday, a day to celebrate Rube Goldberg machines, the over-engineered contraptions that perform a very simple task.

We haven’t built any new machines in a while. Instead we’ve been leafing through a couple of books, talking about complicated and funny contraptions found in them and creating no less complicated drawings for our future machines.

 

Hogwash by Arthur Geisert is a funny story about a whole lot of little pigs going out to play, first in the mud

 

 

 

 

 

 

 

 

 

 

 

 

 

And then at what appears to be an old paint factory.

 

 

 

 

 

 

 

 

 

 

 

 

 

As you can see, the piggies’ parents have a whole lot of cleaning up to do. And here I was thinking bath time at our house was tough. So what do mommy pigs and daddy pigs come up with? They do quite a wonderful job cleaning and drying the piggies.

 

 

 

 

 

 

 

 

 

 

 

 

 

Don’t you love the contraption? We read through this simple, yet charming story and looked through illustrations several times, each time noticing something new. A perfect activity to go along with this book, as we found out, is a water wall, such as this one

 

Or this one

 

Or this water wall that looks like a marble run (it’d probably work with small marbles too).
