In this math lesson, learners use the setting of a flower-making fundraiser to explore a variety of patterns. Learners examine the patterns in a flower design made of triangles surrounding a square. They complete a table listing the number of triangles needed to complete various flower designs. Learners also make tables showing the cost of buying different cut-outs of flowers. These charts will be used once they begin their flower sale. The lesson culminates with learners making brightly colored tissue paper flowers and the advertising posters.
