* Learn about the purposes, structure, and design principles of mandalas.
* Learn about rotational symmetry in mandalas.
* Learn that circles are divided into 360 small slices called degrees.
* Learn the pie-shapes produced by common angles like 180 degrees, 90 degrees, 60 degrees, and 45 degrees.
* Design linear patterns with shapes. Then learn how rotating those patterns can create beautiful and complex rotational symmetry.
* In p5.js JavaScript, learn how x- and y-coordinates control the placement of shapes and images on screen.
* In p5.js JavaScript, learn:
- - - how to draw ellipses, rectangles, triangles, and free-form shapes
- - - add color to the outline or interior of shapes
- - - create and modify variables
- - - use variables to rotate shapes.

15 years of experience teaching JavaScript, Python, Scratch, web development, robotics, and artbotics to students from 8 - 15 years old in private, public, and after-school settings. Two masters degrees in education – from Harvard Graduate School of Education with a focus on technology and from Lesley University in mathematics education. And, most of all, great love, patience, and respect for the many different ways that students learn and the gifts they each bring to the classroom!
