About this worksheet

This free Year 8 rate graphs worksheet is written for the Western Australian curriculum and mapped to SCSA content description WA8MNAUN6. It targets one skill so students can practise until it sticks: by the end, students can say “I can read and calculate rates from distance–time and other graphs, compare travellers and sketch a graph from a story.”

What’s inside

• Key idea box – a short explanation with worked examples to read before starting.
• A · Fluency (16 questions) – quick practice to build accuracy.
• B · Core (10 questions) – worded problems set in everyday Australian contexts.
• C · Reasoning (4 questions) – explain, justify and spot the error.
• D · Challenge (4 questions) – harder multi-step and problem-solving questions for students ready to stretch.
• Separate marking key – every answer with working, plus mark allocations and marking criteria for reasoning questions.

Skills covered

• Reading rates from the slope of distance–time and other graphs
• Comparing travellers on the same axes
• Sketching a graph to match a story

How to use this worksheet

Start with the Key idea box, then complete Section A (use a calculator only where a question says so). Most students should attempt Sections B and C; Section D suits students aiming for the top of the class or preparing for accelerated or extension maths. The worksheet is marked out of 58, and the score box on the last page helps students see which section needs more practice.

Common mistakes to watch for

• Reading a flat section as moving
• Thinking steeper means slower
• Reading the graph as a picture of the route
• Misreading the axis scale
