Connect students directly to the concept in a personal way. Capture students' attention by initiating a group problem-solving activity before delivery of instruction. Begin with a situation that is familiar to students and builds on what they already know. Construct a learning experience that allows diverse and personal student responses. Facilitate the work of cooperative teams of students.

Students brainstorm things without shape.

Objective: To engage students in the awareness that geometry is all around us.

Activity: Working in cooperative learning groups, students are challenged first to brainstorm examples of all things in our natural world that are not basically shaped in the form of cylinders or circles, cubes or squares, pyramids or triangles, or formed from either curved or straight connecting lines. Second they are challenged to brainstorm a list of all things made by man that do not have the same criteria.

Assessment: Participation and contribution to group activity.
