My all-time favorite Good Friday sermon. If the video doesn’t show, see it on YouTube.
Kitten and I have been slogging through the decimals chapter in AoPS Pre-Algebra. She hates arithmetic, so I tried skipping ahead to the algebra puzzle in the exercises, but she refused to be taken in: a decimal problem with an x in it is still a decimal problem.
So I let her off early and pointed her toward these logical “algebra” puzzles instead:
Mathematicians Ask Questions
If we want to teach our children to think mathematically, we need to model and encourage asking questions. For instance:
- What is the difference between the rectangular sounds and the round ones?
- At 5:20, the orange notes (violin) change to a different shape. Why? What change in the sound does this represent?
What questions does the video inspire for you? I’d love to hear your comments!
Due to an apparent glitch with the submissions, it’s a frustratingly short carnival this month. But you will still find plenty of fun, from elementary kitchen math to algebra 2 and fractions to fractals:
The number sixty happens to be the smallest number divisible by the numbers 1 to 6. Also, it has the honour being a unitary perfect number, i.e. it can be interpreted as being the overall sum of its unitary divisors (excluding itself). Give this a try to convince yourself: 1 + 3 + 4 + 5 + 12 + 15 + 20 indeed equals 60.

After teaching co-op math classes for several years, I’ve become known as the local math maven. Upon meeting one of my children, fellow homeschoolers often say, “Oh, you’re Denise’s son/daughter? You must be really good at math.”
The kids do their best to smile politely — and not to roll their eyes until the other person has turned away.
I hear similar comments after teaching a math workshop: “Wow, your kids must love math!” But my children are individuals, each with his or her own interests. A couple of them enjoy an occasional geometry or logic puzzle, but they never voluntarily sit down to slog through a math workbook page.
In fact, one daughter expressed the depth of her youthful perfectionist angst by scribbling all over the cover of her Miquon math workbook:
- “I hate math! Hate, hate, hate-hate-HATE MATH!!!”
Translation: “If I can’t do it flawlessly the first time, then I don’t want to do it at all.”
What do you think math is all about? What do your children think? Here is the start of a promising new video series:
