The Hundred Chart and Game Cards

100 Hundred Chart

It’s been a little while since I did the original post about the hundred chart I put together for my son and his reaction to it. Finally, I have a professionally done (thank you, Ever!) chart you can download, play with, explore and, if framed, admire (it has a certain beauty to it, don’t you think). The chart prints to 1 letter page. Additionally, you can print individual cards and play with those.

Download the low-res PDF hundred chart.

Download individual cards to print.

Download full size high resolution chart. It prints to a 30×60 poster.

As you might know, Maria collects Hundred Charts like the one she shared in our newsletter. So now I’m curious to see other charts in her collection. Have you come across different versions of the good ol’ Hundred Chart? Please let us know!

And if you are looking for games to play with the chart, check out Let’s Play Math post about 20+ things to do with a hundred chart.

Book news

The book cover is ready! This is the version we will be using in the first print and ebook run. Much appreciation to Ever Salazar for many little miracles that turn mere words into real kids playing with real math.

Moebius Noodles Cover Final

Volunteer reviewers are hard at work giving us comments and suggestions, as we prepare the book for copy editing. At all stages, this book is a community effort!

We are actively working on two super-secret projects to support every family or math club using the book. Both will also support young math projects of our colleagues – blogs, books, puzzles, videos… The first super-secret project is a powerful question and answer tool we call “Ask Moby.” Parents and educators will have a quick and easy way to get answers from like-minded adventurous people who appreciate advanced young math. The second super-secret project is also for grown-ups. I am only going to say, for now, that it goes by the code name “The Game.”

Blogs and networks

We reviewed three books on our blog, all of them about the topic of unitizing – that is, making one unit out of several individual entities.

“Unlikely additions” invites you to think what two units you can add to make a given other unit. For example, 1+1=5 if you add wheels of a bicycle (2) and wheels of a tricycle (3).

“Clap, drum and shake it” and “Meadow count” are about gross motor mathematics. In particular, the units are formed out of large movements, then multiplied into patterns – sort of like a dance!

On our Facebook stream, people discuss their metaphors for teaching, inspired by the “square thoughts” picture Zekeria Karadag shared. Pei-Jung Lee sees herself as a humble servant to the desire of learning. Yelena McManaman paves a road, or at least adds lines to it. Think Magnet likes the quote, “”Education is not the filling of a pail, but the lighting of a fire.” What is your metaphor for teaching?

Square Thoughts Metaphor

One of my eccentric hobbies is collecting creative Hundred Charts. The number system we use today is the pinnacle of thousands of years of international research and development. Hundred Charts help us notice some of the patterns that went into this incredible invention. This fresh addition to my collection comes from a young girl named Nomi. Her dad Dor Abrahamson helped Nomi develop the idea into this neat puzzle. Can you figure out how it works? Hints are below the picture.

Hint 1: think of the sum of digits.


Hint 2: think of the number of numbers with each sum.

1+1=5 A scavenger hunt game about unitizing

Yelena recently reviewed the book “1+1=5” and shared the game of “I spy” she plays with her son.

The book inspires kids (and adults) to see everyday objects as sets, or collections of other objects. For example, a triangle can be viewed as a set of 3 sides while a rectangle is a set of 4 sides. An octopus is an example of a set of 8 (arms) while a starfish hides a set of 5 (arms) in plain sight. If one set has 8 elements and another set has 5 elements, then when added, the two sets have 13 elements total. Hooray!

I thought it could be fun to invite readers of this blog to play a round of the game. Here is the big question I am contemplating: “How can we make our descriptions of games we design so interactive that they become, literally, playable games?”

Add your own example! Of course, this is the ocean, for our Moby Snoodles.

This is what people added so far! It takes about five minutes for your answer to appear here. Wait and then reload the page to see!

Moving Through Math: two book reviews

ClapDrumAndShakeItCover MeadowCountCover

 

Learning math through the arts… Moby Snoodles approves! So I was happy to review two books from Marcia Daft’s Moving Through Math project. They are read-aloud books for kids under five and their grown-ups. Both books are illustrated in a distinctive, memorable manner that reminded me of early Japanese watercolors. Of math education aspects, I found notes to parents to be most distinctive and memorable. After a strong book, you can graduate from “What?” (what entities and actions were in the book) – to “So what?” (your new understanding of the world).

Count, Drum and Shake It

What? Use iconic symbols, such as clapping hands or shaking maracas, to form pattern units, such as “clap, clap, shake.” Then repeat the unit to form the pattern. Perform each movement as you get to that symbol in the sequence.

ClapClapShakeUnit

So what? Unitizing is the foundation of multiplicative and proportional reasoning. For example, 5*3 can mean a unit of five repeated three times, or a unit of three repeated five times. Kids need to work and play with units a lot, such as repeating parts of songs and dances. A kid who thinks of any unit as a single building block is well on the way to the idea of variables.

Thumbs up!

  1. The book uses iconic symbols – that is, pictures that show what to do. Iconic symbols help kids transition toward abstract symbols. Iconic symbols are accessible even to babies. If the baby is too young to clap or jump, you can move the baby’s hands in yours, or bounce the baby in your lap as you point out the symbols.
  2. The relatively advanced idea of pattern units is introduced qualitatively (without numbers) first. This helps learners to form strong, grounded foundation for the idea. Qualitative intros work for learners of any age, but are absolutely necessary for young kids.
  3. “Look for patterns in the air, look for patterns on the ground.” For example, walking feet: left, right, left, right… Or flying wings: up, down, up, down… Inviting kids on scavenger hunts after introducing a new math topic? Yes!!! Scavenger hunts help to notice many aspects and details of a topic; they make the topic stick in memory; and they integrate math with the everyday world of learners.

Building on it

  • Do more multiplication. In particular, invite kids to multiply within pattern units. For example, how do you double the pattern unit “clap, clap, shake”? That is, how do you show 3×2 in the language of the book? “Clap, clap, shake; clap, clap, shake” is what the book does. You can also do “clap, clap, clap, clap, shake, shake”!
    ClapClapShake3x2
  • Make the idea of variables explicit. Give your pattern units names. For young kids, the traditional X and Y are too short and abstract for variable names. Invite kids to create and name several pattern units. Kids often name things after themselves, their favorite heroes, or their pets. Let’s say we have these names for pattern units:
    Alice = “clap, clap, shake”
    Bob = “drum, clap”
    Then kids can make patterns out of Alice and Bob!
    Bob, Bob, Alice = “drum, clap, drum, clap, clap, clap, shake”
  • Provide even more support so kids can make their own patterns by transformations of old pattern units. The book suggests two transformations.  Reflection turns “clap, clap, shake” into “shake, clap, clap.” Swap between moves turns “clap, clap, shake” into “shake, shake, clap.” Invite kids to make up their own transformations. Or catch their mistakes in repeating patterns, and turn mistakes into transformations!

Meadow Count

 

What? A traditional counting book, for numbers from one to ten. Children count by making whole-body movements, such as three giant puddle jumps, seven high reaches to the clouds, or eight jiggles down as you wiggle to the ground.

So what? Fine motor skills use some of the same parts of the brain as mathematics. That’s why activities that require fine motor skills, such as playing musical instruments, crocheting and origami, develop “the math brain.” But you don’t want to overwhelm and overload this math brain. Challenging fine motor skills, on top of challenging new math ideas – that can be too much for one activity! That’s why using gross motor movements helps to introduce new math ideas. Whenever I work with kids, I design whole-body methods for introducing each topic, from equations to infinity. This way, the math brain can devote itself to math, without having to coordinate the fine motor movements too.

Thumbs up!

  • Children in the book look and dress like they come from all different continents, without any cliches. Kudos to the artists on this tasteful presentation!
  • One-to-one correspondence is not challenging as an idea: babies are born understanding it. However, the reliable implementation is hard for young kids. Gross motor movements will definitely help to count more reliably.
  • The descriptions of movements are artistic. There are evocative metaphors, such as “count one leafy spin,” and emotions, such as “two happy hops,” and details that go with the story, such as “nine sharp tugs to create a bouquet” when the kid picks wildflowers. Kids love that rich stuff – and relate to math through it!

Building on it

  •  Use more intrinsic quantities to support the number sense. One example in the book is to hop two times to take off both shoes. You could also sprint to each corner of a room (four sprints) or reach to the sky with each finger on your hand (five stretches).
  • Connect counting to pattern units. For example, count to nine again and again as you create many bouquets for all your friends.
