Week 30: Coloring is not Just for Kindergarten

I am trying to tell my 15yr old daughter that an elective high school credit in Graph Theory would be fun next year. Of course I do this as subtly as possible – I start drawing coloring sheets for this post on my iPad and then carefully shade them in. All three of my children slowly sneak up behind me and breath in my ear.

“You know that it will never take more than four colors” I state.

“Really?” I hear my oldest daughter say with a sense of wonder in her voice. “Can I make one?” she asks reaching for my device.

She takes over the iPad. I go for a run. I clean up a bit. She is still designing, thinking, coloring. A wave of gratitude flows over me “Thank God that coloring isn’t just for kindergarten.” We are so blessed to have the abundance and time to be able to color, play, and contemplate.

She finishes her design. “It looks like the beautiful cobbles on our Oregon beaches.” I think, then say.

“That’s what I was going for.” She says. Then gets up and goes back to her school work.

This week I challenge learners to play with coloring sheets. Make your own. Share them. Color them. Contemplate them. Can you restrict the coloring to four colors? It may take some problem solving for more complex sheets.

In graph theory, there is the study of graphs that are made up of nodes (vertices) that are connected with lines (edges). Create a graph for one of your coloring sheets, where the regions are nodes and lines connect the regions that touch.

You could also create a graph with nodes and edges and then the coloring sheet to go with it.

Below are a couple examples (some blank for you, my readers, to use):

Week 18: Castles, Maps and Spaceships – Let’s Draft

This week learners can dive deep into their imaginary worlds (or real world inventions). The project this week is to create a map, castle, spacecraft or invention. The math focus will be on developing a sense of scale. Younger learners may practice scale with proportions in their drawings. Older learners may add units and measurements to their designs.

Offer various materials for their designs: graph paper, extra large sheets, engineering papers, isometric, or hex. Facilitators can supplement learning by looking at maps, blueprints, and patent designs that learners are interested in.
