As a conclusion to their unit on color, first graders used markers to color this bottle and jar "puzzle," demonstrating their knowledge of how secondary colors are made by combining primaries. I started by showing them a version of the puzzle with only the tops of the containers colored so they knew which primaries to start with and in what order, then we walked through how and why the first overlap would be colored purple. From there, they were on their own, though I encouraged them to use the classroom color wheel if they got stuck. Emphasis was placed on coloring with care (no "spaghetti coloring"!), and when they finished, I showed them how to add an oil pastel highlight to make their bottles and jars "shiny."
