Tips for a Happy Math Year – #3

Monday, October 7th, 2013

It’s time for tip #3 in my special series, Tips for a Happy Math Year!

And here it is…

Normalize error.
Getting an answer wrong is just part of the natural learning process. So is getting an answer right. Neither situation calls for high drama. If a kid makes a mistake, say, “Okay, try again,” and ask them what’s the first thing they have to do. This tip comes from Doug Lemov’s great book, Teach Like a Champion.

If you notice your son or daughter beating themselves up over their mistakes, saying things like, “I’m such a bad kid since I got that answer wrong,” “I’m really not good at this,” or “I guess I’m just not a math person,” explain that everyone makes mistakes while they’re learning.

Normalizing error is a powerful way to support your daughter or son in developing a “growth mindset” and being resilient in the face of a challenge – whether that challenge is in math, or in life!

Would you like your kid’s math experience to be less like crying themselves to sleep over their math homework, and more like twirling a sparkly parasol of confident self-expression?

Less feeling like they’re stuck in a mire from which they fear they cannot extricate themselves, and more like Indiana Jones on a great math adventure?

Send me an email at or call me at 617-888-0160, and we can set up a special time for us to have a complimentary conversation.

We’ll get clear on what’s going on in your kid’s math situation and explore whether or not it would be a good fit for us to work together!

It’s eraser time! (And other math mantras)

Monday, November 28th, 2011

Apparently, there are certain things I tell my students over and over. One of them, with a twinkle in my eye and glee in my voice, is, “It’s eraser time!” (Whenever I say, “It’s eraser time!”, I think, “It’s Hammer Time!”, even though that was a hit long before most of my students were born.)

Then my student will jubilantly erase their mistake and then correct their work.

I didn’t realize how much I would say “It’s eraser time!” until my students started saying it *back* to me. Which made me ask myself–how did this become a permanent fixture of my teaching vocabulary? Why does “eraser time” work so well?

Three reasons:

1. Most importantly, “eraser time” normalizes error. It shows students that when they mess up, it doesn’t mean that THEY are messed up. Instead, making mistakes is just a normal part of the learning process.

2. “Eraser time” is fun, even at a moment when students have made a mistake. So it’s energizing, but doesn’t distract from the task at hand. It’s fun and silly but still leads them to what they need to do next — erase.

3. By being part of a special “math tutoring language” that we share, “eraser time” helps students feel like they belong. They are “in the know” because they get our special “insider lingo.” It helps create a culture of trust and camaraderie.

As usual, my students have taken eraser time and made it their own. Variations include an Eraser Race, where we both erase on the whiteboard as fast as we can. There’s also “Strategic Erasing” (careful erasing to remove what you don’t want but leave some previous work up for reference).

Another big mantra that my students started saying back to me is, “When in doubt, write it out.” I love this because instead of me nagging the student to write out the work instead of guessing, the student will happily say, “When in doubt, write it out!” and then go ahead and write out their work.

“When in doubt, write it out” works for the same reasons — it normalizes *effort* (it shows that it’s okay and normal to have to write it out and do the work); it directs them to the next step, but in a way that is fun and helps them “own” the process; and it creates a culture of fun and belonging.

On seriously owning your mistakes

Wednesday, June 16th, 2010

From The Week:

[Jim] Joyce, a veteran major league baseball umpire, last week mistakenly called a runner safe on a close play at first base on what should have been the final out, therefore costing Detroit Tigers hurler Armando Galarraga a perfect game.

Over 135 season and tens of thousands of major league games, only 20 times has a pitcher retired 27 straight batters without a walk, a hit, or an error. Joyce’s blown call denying Galarraga that 27th out, therefore, caused a national uproar.

To his credit, Joyce freely admitted after viewing the videotape that he should have called the runner out, and sought out the 28-year-old Galarraga to apologize. Clearly shaken, Joyce told reporters, “I just cost the kid a perfect game. It was the most important call of my life.” Galarraga hugged Joyce and told him to forget it. “Everybody’s human,” he said.

I was so moved by this that I cried. Mistakes are essential to learning, and we need to make it safe for kids to make mistakes so that they can learn. But we live in a world where it is so rare for anyone to publicly admit they made a mistake. Most public figures, instead of owning their failures, minimize or deny them. To see two public figures handle this huge mistake with such dignity and compassion really inspired me.
