Topic:
 Unit Title: “Filling and Wrapping” Course: Middle School Mathematics Subject Area: Mathematics
Content:
 Finding Volume and Surface of Rectangular Prisms Finding Volume and Surface of a Cylinder VOCABULARY: base, cube, cylinder, face, prism, rectangular prism, surface area, volume.
Goals:
 Standards Middle School Mathematics Standards Sunshine State Standards Benchmarks NCEE New Standards The student uses concrete and graphic models to derive formulas for finding perimeter, area, surface area, circumference, and volume of two- and three-dimensional shapes, including rectangular solids and cylinders. Expectations The student: · Uses concrete or graphic models to create formulas for finding volumes for solids (prisms and cylinders). · Uses concrete or graphic models to create formulas for finding surface area of prisms and cylinders. · Solves and explains problems involving perimeter, area, and circumference. · Solves and explains problems involvingthe surface area or volume of prisms and cylinders.
Objectives:
 The student will: 13.1 Conceptualize volume as a measure of filling an object. 13.2 Conceptualize surface area as a measure of wrapping an object. 13.3 Find volumes and surface areas for rectangular prisms. 13.4 Find volumes and surface areas for cylinders. 13.5 Reason about problems involving the surface areas and volumes of rectangular prisms, cylinders, cones, and spheres
Materials:
 TEXT: FILLING AND WRAPPING INTERNET WEBSITES: MATH GOODIES.COM, AAA MATH.COM, INTERNET4CLASSROOMS AND GOMATH.COM, LAPTOP COMPUTER AND PROJECTOR.
Introduction:
 Remind students that they have learned how to find the surface area of a rectangular prism and will be reviewing that process for this lesson.
Development:
 Using the internet website, students will be introduced to the concept of finding the surface area of a cylinder and the volume of a cylinder. Students will understand that the if the cylinder is flattened, it will form a rectangle. Students will also review finding the area of a circle.
Practice:
 Following the demonstration student will practice finding the surface area of actual cylinders using items in the classroom.
Accommodations:
 Inclusion students will work with a partner to find the surface area AND volume of at least ONE CYLINDER shaped object, provided by the teacher.
Checking For Understanding:
 Students will present their findings to the class.
Closure:
 5 minutes prior to the end of class, students will be asked to respond to the following questions. 1)What did you learn that you did not know before? 2)What was not unclear or confusing to you?
Evaluation:
 1) Teacher observation. 2) Worksheet-Students will find the surface area and volume of a rectangular prism, and the surface area and volume of a cylinder. Students will complete with 70% accuracy
