This problem with multiple solutions is an opportunity for students to practice sorting, classifying, and organizing information. They also learn to recognize, generalize and predict patterns and develop systematic, strategic thinking. Learners create 16 unique combinations from cups and saucers in four colors and then arrange them in an array such that each row and column contains all four colors of each. The Teachers' Notes page offers suggestions for implementation, discussion questions, ideas for extension and support, and a link to a simpler activity, Teddy Town (catalogued separately).
