I'm not sure about your kids but I know my upperclassman still love to color! They can't wait to get their hands on a coloring page even if they have to do math first!
Included are 8 problems (problems do get more rigorous with real world problems of arithmetic and geometric variety) that will help students color the Fibonacci Spiral. After completing the 8 problems, solutions will match up to a color that students will then use to color the Fibonacci spiral.
As mentioned in the included project description, this Color By Number could be a great way to introduce the Fibonacci Sequence where students investigate the spiral and learn fun facts about the Sequence. In fact, there are many great projects out there where students create their own representation of the famous sequence. Take the coloring activity and make it your own!
