  • The Butler Stick  — A New Use for an Old Tool

    The Butler Stick — A New Use for an Old Tool

    I’m at the Domestic Estate Manager’s Association Convention this weekend with Husband and I’ve discovered a marvelous math tool. It’s called “The Butler Stick” and it’s used by butlers and other domestic service personel — mostly.

    But there’s a lot of math in it — enough to integrate The Butler Stick into your world as another learning tool.

    On one side it’s a yardstick.

    The Butler Stick has thirty six fun inches to measure just about anything. It’s foldable, though, so you can store it like a standard ruler.

    You can show an equilateral triangle with it, as well play with various angles.

    On the other side it’s a number line!

    Okay, so it’s missing the negative signs on the left, but those are easily added with a sharpie.

    The Butler Stick is typically used to set a table. The plate is centered at zero, and from there you can symmetrically lay out the flatware and other bits.

    You can use it to teach proper place setting (something every child should know) and inject some math into dinnertime!

    You can also use it to create other things of symmetry. Use it to have fun with math during art lessons.

    Treat your family to one!

    They sell The Butler Stick at Charles MacPhearson’s site, but you have to call to order it (416-369-1146). It’s not cheap, at $24.95, but it’s well made and looks like it would take a beating from a few children. (But not give a beating!)

    Or you could try it out for a while by making your own. Use some some cardboard and rivets and you’ll be able to see the value of it. It’s a crude version, but the math’s the same.

    Once you see how cool it is, you’ll be calling them up — just like me!

    Create Your Own Number Path – at Home!

    I recently read about the difference between a number path and a number line in the book Mastering the Math Rack to Build Mathematical Minds.

    Walking up and down my hallway I noticed the tiles made a very nice number path. So I used some removable whiteboard wall decals and cut them in quarters.

    I wrote the numbers 0-11 on them with a permanent marker and slapped them down on the tiles.

    Later, while reviewing Carlito C. Caterpillar’s Math House Games for The Homeschool Post, I noticed Carlito suggested the same thing!

    My hallway is now a counting lesson!

    When we run down the hallway, now, we say the numbers as we step on them. This integrates counting, recognition of numbers and linearity all with body movement – which serves to solidify the learning.

    Not only that, but the removable decals don’t hurt the floor!

    And there’s more…

    When we were at the ice cream parlor, she noticed the tiles on the floor and started running along them and saying numbers! This was something I didn’t expect at all.

    Not only that, the three sets of three tiles created a number path of 11 when you included the two spacers. I don’t know if she recognized this, or if it was merely a coincidence. But it was fun to see.

    Will you do it?

    You can do this with anything that has a “block” pattern – at home, or in a classroom.

    Let me know if you try it – and the reaction of your kids – in the comments below.

    Disclaimer: The sweet folks over at MathRack.com sent me a bunch of MathRacks and the book, at no charge, for me to check out and report to you on, if I wanted to. You’ll be seeing more articles about these soon (they are really cool!).
