Both of the Intermediate challenges use number patterns to create artistic designs.
Another difference is that I combined levels A & B, as well as levels C & D. I really feel that no matter what grade level your child is in, they are able to do all 4 challenges (of course with varying levels of support). If your child is in grades 3,4,5 ... and would like to do the Primary challenges ... I am going to expect them to think about how they can "ramp" it up a bit. Can they make the activity appropriately challenging for them?
I've included some links below that offer additional information on both Spirolaterals and Parabolic Curves.
The Art of Spirolaterals by Robert J. Krawczyk
This article is AWESOME! I wish I had found it when I first started teaching this lesson. It talks about the concept, the math, and the variety of designs that you can create.
Spirolateral video from the blog, What Do We Do All Day?
This blog is new to me, but so far I am loving it. I adapted her lesson for this challenge. There is a video of her child creating a spirolateral in case you want to see it in action before trying it out yourself.
Additional Spirolateral activity by NRICH Mathematics
NRICH continues to be one of my favorite math education websites (It's not just for teachers so check it out!). This is the original lesson that I started using years ago.
Curve Stitching from the blog, Wonder How To
Making Parabolic Curves with BBQ skewers from the blog, Wonder How To
Fun looks at additional ways to create these patterns and designs.
A Parabolic Curve activity from the blog, What Do We Do All Day?
Images of Parabolic Curve Art - I googled Parbolic Curve Art and clicked on "images"
Totally worth checking out!
Lastly ... while searching and deciding on which activities to use for Challenge #9, I stumbled upon this. What seems like a million years ago now, I taught an Art and Mathematics class to 4th and 5th graders at Coe Elementary. We did a super cool activity with paper folding. I took pictures of the students' work, and submitted them to NRICH. How cool to find that they were still there!
I can't tell you how excited I am to not only share these experiences with our QAE students, but also to see what they do!
As always, thank you so much for all of the support that you give to your budding mathematicians. As Jo Boaler says ... Vive La Revolution!
