    Spoiler Alert! Penny Puzzle Solution

    I posted this puzzle on Facebook this past week.

    Can you move 3 pennies and form a triangle that points down?

    Here is the solution:

    I’m a math teacher so I love looking at different solutions and explanations. Here are some of my favorites from the comments on Facebook:

    You move the three points. Top point move to center bottom to be the new lower point. The left and right points, move them up to what is now the top row, so that you now have 4 across the top.

    • Turn the paper so that it faces down. (haha!)
    • Right bottom penny to the bottom center, left bottom penny to the left of the second row, very top penny to the right of the second row.
    • Shift the three outer “points” clockwise. You could also shift them counterclockwise for the same result.
  • Learning How To Learn: Barbara Oakley at TEDx

    Barbara Oakley is a top educational researcher and a professor of engineering. But she wasn’t always a math person. Originally interested primarily in languages and cultures, she made a career change at age 26 (reminds me of myself…I pivoted from French to mathematics when I started college). In this video she explains what she learned about her brains through that process.

    The video is a great resource for parents or homeschool students. Learning how we learn makes us all better students.

  • Simple Steps to Nurture a Child’s Natural Love for Learning (Part 1)

    Girls with magnifying glassDo you realize the wonderful potential you have to keep your child’s natural curiosity and innate interest in learning alive? Here is an 8-minute cut from a short talk I did for a small group of women hosted in a friend’s home. (Part 2 will post on Monday, August 12.)

  • Q: How late should I let my teen sleep in?

    It’s Dr. Deb Fridays…a weekly blog post about a pertinent question. I’ll weigh in with my thoughts but we’re looking to leverage the wisdom of the crowd on these pressing issues.

    My husband and I have always been early risers. Must be in the genes–his parents were both raised on a farm and maintained a lifelong habit of getting up before the crack of dawn. My parents, as teachers, likewise were always up quite early, talking loudly in the kitchen. During my homeschooling years, I liked to get things moving by 7 AM and stopped serving breakfast by 8. That changed as each of my kids entered early adolescence. They started sleeping later and later, and I often had to make several rounds before they were out of bed.

    School started dragging on the other end, too. I liked to be done by at least 3 PM so I could get dinner (that rare occasion in my house) or laundry going. But my teens liked to do school at night and they wanted my help even though I had that “OFF DUTY” sign around my neck. Because I had plenty of other fronts to maintain, I chose to let them set their schedules. It worked out for us just fine. My adult children are now all early risers, too.

    Teenagers do need more sleep during the height of adolescence. Their bodies are changing and their brains are growing. The average, doctors say, is nine hours a night, similar to the needs of a two year old (who likewise are experiencing dramatic, accelerated growth).

    What do you do at your house? Is there an absolute deadline for getting up and going to bed? What principles inform your thoughts in this area?

  • You Can’t Teach Anyone Anything…You Can Only Motivate!

    I generated quite a bit of discussion on my Facebook page last week when I posted this provocative statement: You can’t teach anyone anything, you can only motivate someone to engage in learning. What do you think? Is that true?

    My point is this: If your child doesn’t choose to turn on her brain, focus her attention on the topic at hand and think about what you are presenting, it doesn’t matter how well organized or compelling your lesson is. You might be teaching, but the child isn’t learning. She has to flip on that light switch inside first.

    We learn what we think about, and the learner is always in control of just what that is going to be. You might be doing a tap dance and a jig at the front of the room, and your son might be staring right at you, but his mind could be a thousand different places.

    So, is there anything we can do about this? You bet: We can motivate. First, God has given your kids the gift of curiosity. Use that to your advantage.  One way to grab their attention is to pique their interest. You can do this by asking a provocative question (like I did in the first paragraph.) Another way is to show them something unusual or new. We are easily bored and lose interest in the familiar.  Or use the element of suprise. Break the routine. Announce a mystery guest or an unplanned field trip.

    One quick don’t. Don’t insist a child pay attention or use negative consequences and threats. I know this statement is controversial. We tend to view a lack of attention as a character weakness. And maybe it is sometimes. But here’s the rub: Our ability to learn is reduced when we feel upset, threatened or stressed. Any source of negativity decreases our ability to engage in learning. Think about yourself in a similar situation. Can you process a lot of information when you are upset? Can you give your full attention to reading a book or exploring new terrain if something stressful has just happened? That’s my point. We actually learn more when we are happy and relaxed. Laughter is even better — so start the day with a belly full of giggles as a warm-up exercise for the brains in your house.

    I see this process as God-designed. He wants us to view our ability to learn as a blessing and a source of enjoyment. That’s why He’s hard-wired us to learn, and lifelong learning is the secret to healthy brains and a satisfying life. Curiosity is the fuel that keeps our minds active — so leverage that the next time you call your kids to class.

    Are your children motivated to learn? What do you do when they aren’t?
