6:49 AM | What to Do When You Are Busy
Today, one of the things I read over the summer came back to me. The thing I read was written by a therapist, regarding his patients who are stressed and unhappy because they feel like they're spread too thin among work, family, friends, etc. The therapist's advice is that you cannot make more minutes in a day, but you can increase the quality of your minutes in the day. If you're thinking of work when you are at home, and thinking of home when you're at work, then you're not making anyone […]

5:20 AM | WSQ = WiSQ
WSQ - It stands for "Watch-Summarize-Question" and it's the idea/method/thing I came up with way back in January 2012 when I was brainstorming to find a way to hold my students accountable for actually watching the video lessons and coming to class ready with questions and to apply their knowledge.  I've always pronounced it "Wisk", like the kitchen gadget you mix pancake batter up with.  I think I may be adding something to it to make it a little more phonetic...Jon Bergmann had a […]

3:04 AM | Mutt vs Gmail Revisited
I used to use Gmail; I thought about switching to Mutt last summer. I decided to try Mutt for the summer to see what happened. Something surprising happened. But first, I will briefly compare Gmail to Mutt: I like that they are both heavy with keyboard shortcuts. I find that I am get through my […]

1:20 AM | Because I Used to Think…
One of days…when I need a reminder… Student: Why do you do it (teach)? I paused… because at some point, I used to think I could make a difference. Student: For some of us, you still are. This coming from a student who is making tiny steps progress.  Still not where we want to be, […]

11:00 PM | On This Day in Math - October 2
Euler calculated without effort, just as men breathe, as eagles sustain themselves in the air.~François AragoThe 275th day of the year; 275 is the number of partitions of 28 in which no part occurs only once. (Students might try finding the similar number of partitions for 10, or some smaller number to get a sense for how they grow)EVENTS479 B.C.: an Annular Solar Eclipse known as "Xerxes' eclipse" as noted by Herodotus occurred.

9:26 PM | Teach Fractions with a Loaf of Bread
Teach Fractions with a Loaf of Bread You own a bakery and the only thing you sell are loaves of bread. Not only that, but every loaf is identical. So when customers come into your shop they just say how many loaves they want.. {1,2,3,4,...} One day a customer comes in and explains that they love your bread but your loaves are too big. They ask if you have smaller loaves. You don't. But then you have a creative idea. You take a knife and cut a loaf into 2 equal sized pieces. You sell one piece […]

7:00 PM | Number Sense, Logic, Perseverance
Four of my five blocks this year are dedicated to teaching Fundamentals of Algebra 1. It's a double block course so I have two classes. They are filled with students with IEP's (one class is all IEP's and the other is mixed but the kids turned out to be about the same level despite a technical difference in the labels on the courses) and so I get to work with my awesome co-teacher from the special education department (this is our fourth year teaching together!). Since we have so much time we […]

2:18 PM | Ramanujan - A Mathematical Mystery
Ramanujan - A Mathematical Mystery On 16 January 1913, Srinivasa Ramanujan wrote to G. H. Hardy. Ramanujan was a self taught mathematician from a small village in India. He had almost no formal training in mathematics. Hardy was professor of mathematics at Cambridge University and one of the leading mathematicians in the world. The letter sent by Ramanujan contained a sampling of theorems he had discovered. Hardy later said, "the theorems defeated me completely; I had never seen anything in […]

1:49 PM | The Pitfalls of Precalculus
The Pitfalls of Precalculus: David Bressoud: Many of the students who aspire to study science or engineering never manage to get through calculus. For many if not most of them, the stumbling block is not calculus as such; it is an inadequate grasp of the mathematics of precalculus. This is why most colleges and universities administer a placement exam and offer a course called Precalculus.[…] [source: mme rss]

1:00 PM | Mashable: In Defense of Math
I had fun contributing to this Mashable piece, “In Defense of Math:  7 Reasons Numbers Rule“. I, and a few other Math for America master teachers, were asked to pitch some ideas for a light-hearted refutation of the all-too-common “I hate Math!” refrain. A couple of my ideas made it in, and I doubt it’s hard […]

9:00 AM | On Comparing Decimals Like 0.999...
Today in my college algebra class will be the first time that I've provided space to actually discuss the 1 = 0.999... issue. Previously I mentioned this here on the blog. This become so contentious that it's actually the only post on which I've ever been forced to shut off comments. (Actually it attracted a stalker who'd post some aggressive nonsense every few days.) Anyway, brushing up on some points for later today let me see a very obvious fact that I'd overlooked before and that is: […]

9:00 AM | 277.42 reasons why we shouldn’t readopt the imperial system
“We do these things… not because they are easy, but because they are hard.” – John F. Kennedy I love a challenge. I go out of my way to do Hard Sums in my head, in the hope of one day matching the Mathematical Ninja’s prowess. I run long distances. I juggle childcare with a tutoring business. I work with children, as a choice. Difficult things? I love them. But they’re no way to run an education system. I genuinely can’t believe I have to write a blog post explaining to the […]

I bet you have all seen the following mistake: There’s a problem here, but it’s certainly an understandable problem. It comes from, dare I say, a trick that we all teach. And it’s a trick we all think isn’t one – adding the same thing on both sides of the equation. When I did my […]

I had rearranged my units this year so that the unit with solving equations and inequalities was first since on the initial benchmark I gave, …Continue reading

2:05 AM | Base Ten Blocks and Math Anxiety.
I have seen students whose confidence is so shaken by calculus or algebra that adding small numbers is no longer certain....the reptilian brain kicks in even basic operations become difficult...too much stress or anxiety and you can literally do about two things: fight or flee. This is why in martial arts you fight calmly and better yet with no conscious mind....otherwise the reptile kicks in and you can't remember what to do even if you have practiced for certain situations 1000 times.
