Fifth graders learn to measure the space inside a box-shaped solid, first by counting unit cubes and then by multiplying length, width, and height.
Students will be able to…
A moving box, a fish tank, a shipping container: all hold a certain amount. How do we measure the space inside a three-dimensional shape?
Project this and answer each question about finding the volume of rectangular prisms — read the explanation after each one.
Tap any phase to open the teacher moves and student actions.
How many small cubes would it take to completely fill this box?
Students answer questions about finding volume.
Students find volume two ways.
Students build a box to a target volume.
Students reflect on volume vs area.
Aligned to the Common Core State Standards for Mathematics.
Recognize volume as an attribute of solid figures and understand concepts of volume measurement.
Measure volumes by counting unit cubes.
Relate volume to multiplication and apply V = l × w × h and V = b × h.
Use appropriate tools strategically.
