DIY Ellipse Maker

As a designer from way back I have ellipse guides from when drafting was done by hand.  Even though I don’t use them for drafting anymore they are a nice to have craft items.  I won’t suggest you run out and buy some as they are a tad expensive and and come in so many projections as well as sizes that you’ll never have the exact one you need.

By now you are probably have a project in mind or maybe you just have a strong urge to draw a perfect ellipse.  Well don’t fear!  Your crafts needn’t suffer!  I am going to show you how to make an adjustable ellipse tool with a popsicle stick and a piece of embroidery floss.

It is mostly easy to make, semi easy to use, and teaches you about the geometry of an ellipse at the same time!  It’s a win, win, win!

Acorn Math Game

There’s a little squirrel family that lives in a hollow log in our backyard thicket they share with a rabbit family and a slew of noisy sparrows.  Mother squirrel has been sending her young squirrels Edmund, Edwina and Forest out everyday for the last three days to collect acorns to save for winter.  The first day all three young squirrels came back with five acorns each.  The second day Edwina wasn’t feeling well and staying in bed but Forest and Edmund returned with five each again.  On the third day, all three squirrels collected five but Forest and Edmund each snuck one before returning home.  How many acorns do the three young squirrels have to show for three days of collecting?

I think these squirrels are going to have to step it up if they want acorns all winter!

Do you have acorns in your yard?  How about collecting some and trying your own math games!

The Math of Motherhood starts in the parental planning phase.  If I have a baby at 38 I will be what age when this baby graduates high school (38 + 18 = ?), college, If this child marries at 30 how old will I be, and so on.

2. Estimating…

Next, comes conceiving and estimating the best time to try. Then, of course, there is your estimated due date which is calculated at forty weeks from the day of you last period with that fun little round tool you doctor or midwife uses.

Spiral shell

We just got through reading Swirl by Swirl: Spirals in Nature, a wonderful picture book written by Joyce Sidman with beautiful detailed scratch-board illustrations by Beth Krommes.  The illustrations are bold, colorful, and full of texture.  It is about reoccurring shapes in nature specifically the spiral.  The book show many examples, explains some of the functional benefits (for example an animal might curl up in a spiral to conserve heat), and celebrates the inherent beauty of spirals.  At the end it also explains spirals as mathematical patterns.  Continue reading →
