Sam V. and Tess V. Shovel, ace volume investigators, are on a case for the Ancient History Museum. Someone has stolen the liquid contents of an ancient jar in the museum's collection and Tess and Sam must find the thief. Through some clever detective work (more than once involving volume measurement), the youthful heroes track the thief to a suspicious dairy barn. This story sets the context for explorations with volume in Lessons 7–10.

Content in this Lesson

  • Measuring volume in metric units (cubic centimeters) and customary units (gallons).
  • Solve multidigit multiplication problems using mental math strategies [E3].
  • Solve multidigit division problems using mental math strategies [E4].
  • Multiply one-digit whole numbers by multiples of ten [E5].
  • Solve multistep word problems involving the four operations [E8].
  • Use the relationship between larger and smaller units of measure to solve problems [E9].
  • Using multiplication and division to solve problems involving volume.
