Gordon Hamilton of Math Pickle recently posted these videos on how to make algebra 1 puzzles on rectangles. As I was watching, Kitten came in and looked over my shoulder. She said, “Those look like fun!”
They look like fun to me, too, and I bet your beginning algebra students will enjoy them:
Here is yet another wonderful summer math opportunity for homeschoolers or anyone who works with kids: a free, 3-week mini-course on math problem solving for all ages.
The course is being organized by Dr. James Tanton, Dr. Maria Droujkova, and Yelena McManaman. The course participants include families, math clubs, playgroups, and other small circles casually exploring adventurous mathematics with kids of any age.
Would you like to join us? Check out the mpsMOOC13 home page for instructions. The deadline for joining is July 7 July 3.
And then the real fun begins!

If you want your children to understand and enjoy math, you need to let them play around with beautiful things and encourage them to ask questions.
Here is a simple yet beautiful thing I stumbled across online today, which your children may enjoy:
It reminds me of string art designs, but the app makes it easy to vary the pattern and see what happens.
I liked the way the app uses “minutes” as the unit that describes the star you want the program to draw. That makes it easier (for me, at least) to notice and understand the patterns, since minutes are a more familiar and intuitive unit than degrees, let alone radians.

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:
If we want to teach our children to think mathematically, we need to model and encourage asking questions. For instance:
What questions does the video inspire for you? I’d love to hear your comments!

New Year’s Day
Now is the accepted time to make your regular annual good resolutions. Next week you can begin paving hell with them as usual.
Yesterday, everybody smoked his last cigar, took his last drink, and swore his last oath. Today, we are a pious and exemplary community. Thirty days from now, we shall have cast our reformation to the winds and gone to cutting our ancient shortcomings considerably shorter than ever. We shall also reflect pleasantly upon how we did the same old thing last year about this time.
However, go in, community. New Year’s is a harmless annual institution, of no particular use to anybody save as a scapegoat for promiscuous drunks, and friendly calls, and humbug resolutions, and we wish you to enjoy it with a looseness suited to the greatness of the occasion.
— Mark Twain
Letter to Virginia City Territorial Enterprise, Jan. 1863
For many homeschoolers, January is the time to assess our progress and make a few New Semester’s Resolutions. This year, we resolve to challenge ourselves to more math puzzles. Would you like to join us? Pump up your mental muscles with the 2013 Mathematics Game!
Vi Hart is back with some wintery fun!
