Khan Academy - BRAINTEASERS 6 Ways Learning Math Is Like Being in a Casino I’m in Las Vegas for the DevLearn conference this week. Since I’m always thinking math teaching and now I’m seeing casinos, I’m noticing some comparisons between the two. Here they are: You don’t know if you’ll be successful when you sit down at the table. We think math is something kids can just learn if they sit down and focus. Sometimes it’s exciting and sometimes it’s stressful. When a kid’s totally getting it, it’s very exciting. Everyone has a preference. Just like some people prefer slots over blackjack, kids will tend toward liking one type of math over the other. It’s not about who you think it’s about. When you’re in a casino, you think it’s about you. When a kid’s doing math, it should be all about them. Often it’s about the bureaucracy, politics and laws surrounding education. Once a child is asked to follow the book, or keep to a schedule that isn’t their own, it’s no longer about them. There are plenty of distractions to get your mind off the real goal. Your thoughts? Success!

Well, newsflash, that part of your brain just left you a note -- it says it's been feeling a little neglected lately. When I was in graduate school a friend told me there is no greater urgency to clean your house than when you have a dissertation to write. We feel guilty, we feel lame and we feel completely lacking in self control, but apparently what we should feel is like a normal human being in the 21st century. The number of people who admitted to procrastinating quadrupled between 1978 and 2002. 2002?

science encyclopedia How to Learn Without Memorizing Photo by Edwin Stemp Rote memorization is an inefficient way to learn. Just retaining a single formula can mean pounding the same information into your skull dozens of times. Unfortunately, you’re stuck with your brain. A few years ago, I noticed that smart people seemed to learn differently than most other people. While there are undoubtedly some genetic advantages that allow some people to learn effortlessly, I think part of this difference in success comes down to strategy. Is Your Brain a File Drawer or a Web of Ideas? A computer stores information as thousands of electrical 1s and 0s in a linear fashion. However, your brain isn’t a sequence of bits and bytes, so this approach doesn’t make sense. Other Forms of Learning What I’d like to advocate in this article is a more creative, spontaneous form of learning than the style you were probably coached for in school. There are lots of ways you can learn creatively: 1. You can do the same thing with less technical subjects. 2. 3. Examples:

Learning to love math Recently I wrote about how we have been struggling with Kyri’s attitude. Often when we would start working on our math work for the day, she would immediately get huffy, turn around in her chair and just completely shut down. I know she is a bright girl, and so it would pain me to hear her say she hated math, because I know she GETS it, her frustration just gets in the way. I have been working to really listen to her, to try and figure out what she needs, rather than just respond to the behavior. Some days this is easier said than done, but overall we have made significant process. Second, I changed our approach completely, at least for a short while. Another thing that I learned when I started really listening to her is that she has been anxious to start time and money – my plan has been to finish working through place value before moving on to time and money, but for some reason she is really excited to start the next topic.

How to Become an Early Riser It is well to be up before daybreak, for such habits contribute to health, wealth, and wisdom. – Aristotle Are morning people born or made? In my case it was definitely made. In my early 20s, I rarely went to bed before midnight, and I’d almost always sleep in late. I usually didn’t start hitting my stride each day until late afternoon. But after a while I couldn’t ignore the high correlation between success and rising early, even in my own life. … and the next morning, I got up just before noon. Hmmm… I tried again many more times, each time not getting very far with it. It’s hard to become an early riser using the wrong strategy. The most common wrong strategy is this: You assume that if you’re going to get up earlier, you’d better go to bed earlier. It seems there are two main schools of thought about sleep patterns. The second school says you should listen to your body’s needs and go to bed when you’re tired and get up when you naturally wake up.
