Compute cost of structure by using multiplication skills or calculator. Identify problems, successes, revisions, and purpose of lesson by group discussion and answering questions on worksheet. Each group will need a cleared floor area, and assigned materials.
Teacher explains objective and models materials without actually building a structure.
Allow 3-4 minutes for groups to brainstorm on how to begin. During building time, math person keeps a tally of material costs. Allow students 5 minutes to discuss questions. Recorder transcribes student responses to worksheet. Spokesperson for each group discusses structure and worksheet questions to whole group.
