About this worksheet

This free Year 7 one-step equations worksheet is written for the Western Australian curriculum and mapped to SCSA content description WA7MNALE1. It targets one skill so students can practise until it sticks: by the end, students can say “I can solve one-step linear equations using inverse operations and check my solution by substitution.”

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

• Solving one-step equations with inverse operations
• Writing equations from word problems
• Checking solutions by substitution

How to use this worksheet

Start with the Key idea box, then complete Section A without a calculator. 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 55, and the score box on the last page helps students see which section needs more practice.

Common mistakes to watch for

• Using the wrong inverse operation
• Solving m − 9 = 20 as m = 11
• Not checking the answer
• Misreading 6 − w = 5
