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.
Brainstorm things that have growth patterns, i.e.. things that expand/contract.
Objective: To create an awareness of things that change in size.
Activity: Students brainstorm or cluster about things that have growth patterns, i.e.. things that expand or contract. Examples: interest on money is growth at a constant rate, Fibonacci's rabbits (from previous wheel), population growth, cells dividing in science class and the circles formed from dropping a stone into water. Depreciation on a car, the bounces of a ball dropped from high, or an echo as it fades out could be examples of growth decay or contraction.
