Students will be able to measure circumferences in inches.
Students will be able to compute radii and diameters, given different
The strategy will incorporate cooperative learning, and direct teaching
techniques. The direct teaching method explains the objectives and how to
measure the circumference in inches and compute the radii and diameters.
Cooperative learning encourages the students to interact to formulate the
Direct teaching techniques: A short lecture is given on how to measure the
circumference in inches and compute the radii and diameters.
Cooperative Learning: Students will form three groups. Each group will be given
a tape measure and cans. Each group will try and determine which can has the
largest circumference, radii and diameter. Students will compute and compare
their data. Next, students will be go to five workstations to measure the
circumference and compute the radius and diameter of a light pole and four
different size trees.
Students will be given twenty objects to compute their circumferences after
measuring the diameters and radii.
