Year 5 Maths Lesson Plan: Volume of Cubes and Cuboids
Free Year 5 maths lesson plan on estimating and calculating the volume of cubes and cuboids by counting cubes and using length × width × height.
Learning objective
I can estimate volume by counting cubes and calculate the volume of a cuboid using length × width × height.
Key vocabulary
- volume
- cubic units
- capacity
- cuboid
- estimate
Curriculum: National Curriculum 2014: Year 5 Mathematics — Measurement
Starter (5-10 minutes)
Show two boxes — pupils estimate which has the larger volume and justify. Reveal that today they will learn an exact method.
Main activity (35-40 minutes)
Use multi-link cubes to build a cuboid (e.g. 3 × 2 × 4 = 24 cubes). Lead pupils to derive the formula volume = length × width × height. Pupils complete a worksheet calculating volume for six cuboids. Move to a real-world problem: 'A water tank measures 2 m × 1.5 m × 1 m. What is its capacity?' (3 m³). Final task: distinguish volume from capacity using a beaker of water.
Differentiation
Support
Build cuboids physically with multi-link cubes and count. Then count by layers to introduce the multiplicative idea.
Core
Apply the formula length × width × height to cuboids with whole-number dimensions. Connect to capacity using cm³ ↔ ml.
Stretch
Find missing dimensions given volume and two of the three dimensions. Apply to compound 3D shapes by partitioning.
Plenary (5-10 minutes)
Show two cuboids with different dimensions but equal volume (e.g. 4 × 3 × 2 and 6 × 2 × 2). Pupils explain how this can be true.
Common misconception to watch for
Pupils often confuse volume with surface area, especially when both are introduced near each other. Use a single physical cuboid to point at each: surface area = the wrap; volume = the inside fill.
