Perfect for Pi Day (3/14) or St. Patrick's Day (3/17)! This coloring worksheet teaches kids of any age the basics of polar coordinates and a cute way to remember the tricky fact that pi is only halfway around the circle... it takes 2 pi to go all the way around!
COMPANION CRAFT IDEA:
Make this clock fraction craft so that the rainbow is slowly revealed starting from the correct spot. Maybe if you flip it over to the back it would be a greyscale/emo "negative" rainbow going the other direction.
