Shapes and Volume: Lesson 1 (Volume of Three-Dimensional Figures)

In this lesson, students will understand volume as an attribute of solid figures that is measured in cubic units. Find the volume of concrete three-dimensional figures. Find the volume of rectangular prisms by counting unit cubes. Use correct units and notation when recording the volume of a three-dimensional figure, including cubic units, cubic centimeters. You might want to construct multiple open-top containers so that students can explore volume in a more hands-on way rather than the figures being presented at the front of the class. At each station, construct a figure with centimeter cubes with a volume less than or equal to 20 cubes. Make some of the figures rectangular prisms and others more irregular.
