About this worksheet

This free Year 5 volume with cubes worksheet is written for the Western Australian curriculum and mapped to SCSA content description WA5MMGTH3. It focuses on one skill and is full of hands-on activities where children shade, draw, label and complete diagrams. By the end, students can say “I can build and compare rectangular prisms from cubes and find their volume in cubic centimetres.”

What’s inside

• Key idea box – a short explanation with a worked, visual example to read before starting.
• A · Warm up (16 questions) – quick draw, shade and write practice to build confidence.
• B · Practise (9 questions) – worded problems in everyday Australian contexts, most with a diagram to work on.
• C · Think it through (5 questions) – explain your thinking: spot the mistake, true or false, always–sometimes–never, odd one out.
• D · Challenge (3 questions) – harder multi-step and problem-solving questions for students ready to stretch.
• Separate marking key – every answer with working, the correct shading and drawings shown in colour, and marking criteria for reasoning questions.

Skills covered

• Building rectangular prisms from cubes
• Finding volume by counting rows and layers
• Writing volume in cubic centimetres

How to use this worksheet

Print the worksheet in black and white – all shading shows clearly in grey. Read the Key idea box together, then complete Section A. Most students should attempt Sections B and C; Section D suits students aiming high or preparing for extension and selective-entry maths. The worksheet is marked out of 56, and the score box on the last page shows which section needs more practice.

The diagrams follow the styles used in NAPLAN numeracy, so this sheet doubles as NAPLAN practice.

Common mistakes to watch for

• Counting only the cubes that can be seen
• Thinking the taller prism always has the bigger volume
• Thinking adding one layer always doubles the volume
• Writing cm² instead of cm³

Where this fits in the WA Year 5 sequence

Volume with Cubes sits in the Three-dimensional space and structures sub-strand of Measurement and geometry. It is one of a set of short, single-skill EduLift worksheets that split each Year 5 content description into sub-skills. Use the previous and next links to work through the sequence in order.

Common errors we see in tutoring
