This document provides a detailed lesson plan on teaching students about the volume of rectangular prisms. The objectives are for students to be able to derive the volume formula, find volumes, and work cooperatively. Activities include reviewing area formulas, using a Rubik's cube as a visual aid, presenting the volume formula, having students practice calculation problems, and applying the formula to word problems. Formulas taught are Volume = Length x Width x Height (V=lwh) and Volume = Area of Base x Height (V=Bh). Students are evaluated through table and word problems.
