lessonfieldWhat they’re learning
Your child is solving more complex measurement problems involving area, surface area, and volume. They should select formulas based on what is being measured.
Explain it to my child
Volume is the space inside a 3D object. Surface area is the total area of all the outside faces.
Try it together
Use a cereal box. Measure its length, width, and height. Estimate and calculate volume, then sketch the six faces and reason about surface area.
Practice
- Volume of 8×3×5 prism?
- Area of triangle base 10 cm, height 6 cm?
- A cube side 4 cm has what volume?
- Which measures wrapping paper for a box: volume or surface area?
- Prism base area 20 cm², height 7 cm: volume?
Check understanding
- Can your child identify what quantity a problem is asking for?
- Do they use square versus cubic units correctly?
