About this worksheet

This free Year 5 mass worksheet is written for the Western Australian curriculum and mapped to SCSA content description WA5MMGNS1. 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 choose g, kg or t, estimate mass, and read and draw pointers on scales.”

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

• Choosing g, kg or t and estimating mass
• Reading and drawing pointers on scales
• Converting between g, kg and t

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

• Thinking a bigger object must be heavier
• Counting each small step on a scale as 1 g
• Thinking 1 kg of feathers is lighter than 1 kg of bricks
• Writing 2 1/2 kg as 250 g
