Interactive Function Machines Algebra Maths Mastery Lesson | KS2, GCSE, 11+ Practice (Digital Download) | 8 Units | 100 Questions

Interactive Function Machines Maths Lesson | Digital Download | KS2, GCSE and 11+ Practice

Help your child master function machines, inverse operations and early algebra with this interactive digital maths lesson from Maths by SHLC.

Function machines are a key bridge between arithmetic and algebra. Students need to understand how to follow a rule, reverse a rule, build expressions and solve “I’m thinking of a number” problems.

This lesson teaches the method clearly, then gives students structured practice that gets harder step by step.

HOW IT WORKS

This lesson runs in your web browser. No app, software download or login is needed.

After purchase, you will receive a PDF access file containing the lesson link and instructions.

Students open the lesson on screen, click through worked examples, answer the practice questions on paper, then click to reveal the correct answers and check their work.

WHO THIS IS FOR

This resource is suitable for:

• Parents supporting maths at home
• 11+ students preparing for entrance exams
• KS2 students learning inverse operations
• KS3 students starting algebra
• GCSE Foundation students revising algebra basics
• Tutors and teachers who want a structured digital lesson

WHY THIS LESSON HELPS

Many students can follow a simple rule, but struggle when they need to reverse the rule or turn the machine into an algebraic expression.

For example, if a function machine multiplies by 3 and then adds 2, students need to understand both the forward process and how to undo it.

This lesson builds from simple number machines to harder algebra machines and worded problems, helping students practise the skills needed for 11+, school tests and GCSE Foundation Maths.
