Learning Objectives

Students will be able to model volume with base-ten cubes using the formulas V = l × w × h and V = b × h.


(5 minutes)
  • Show your class a handful of base-ten cubes and ask, "What kind of container could you fill with these with with little to no air space?” Have them turn and tell a neighbor.
  • Have students share out their ideas with the whole class.
  • Share a magnified base-ten cube and describe the features using words like length (side-to-side), width (depth, front-to-back), and height (how tall top-to-bottom).
  • Explain to your students that volume is the area of space something takes up.
  • Explain that the area of the base-ten cube is one cubic centimeter. That volume is calculated with this formula: Volume = length (l) width (w) height (h) - or - V=lwh.
