Step 1/2: Explorations in Teaching Secondary Mathematics and Science Title of Lesson: How Much Do They Hold? UFTeach Students’ Names: Meghan Wilder Teaching Date and Time: Monday, April 7, 2014; 9:15 AM Length of Lesson: 50 minutes Grade / Topic: 6th – Advanced/Volume of Rectangular Prisms Source of the Lesson: http://illuminations.nctm.org/Lesson.aspx?id=2927 http://www.mathsisfun.com/definitions/rectangular-prism.html Appropriateness for Middle School Students: In this lesson, students will be working in pairs. Having students working in pairs will allow them to develop vital communication and cooperation skills necessary for molding them into productive members of society. Group work will also allow the students to learn how to collaborate with their peers and exchange thoughts and ideas freely. Additionally, this lesson will allow the students to be hands-on; the students will be constructing models of rectangular prisms, which will help them visualize the connection between the volumes of the prisms and their dimensions. Concepts: A prism is a three-dimensional figure with two congruent parallel bases and rectangular faces for sides. The different parts that contribute to a prism are vertices, edges, bases, and faces. This threedimensional figure is named by the polygon that makes up its base; therefore, there are multiple types of prisms, including hexagonal, rectangular, and triangular. These prisms can be found everywhere, ranging from a cereal box to all the way to the Pyramids in Egypt. This lesson will focus on the rectangular prism, more specifically on the volume of rectangular prisms. Volume is the measure of how much space a threedimensional object can take up or the amount it can hold. When measuring the volume, cubic units are used because three dimensions, the base, width, and height, are multiplied together. Another way to find the volume is to consider how many unit cubes it can contain. A unit cube is a simple cube used to measure one inch, one centimeter, or whatever the units of measurement being used are on all sides. In this lesson, students will discover the meaning of the equation of volume for the rectangular prism. Mastering this concept will help the students to determine the volume of other prisms, such as the triangular prism; this will in turn prepare students for future mathematics courses and other physical sciences. Additionally, developing an understanding of the volume of rectangular prisms will help students recognize the amount of material a prism, such as a pool, can hold or the amount of material is needed to make a rectangular prism in everyday life.
