Engineering Maths: Measuring and Tolerances | GCSE Resit

Will that shaft pass inspection? Reading steel rules and digital calipers, comparing decimals, converting inches and checking ± tolerances on real workshop parts. A complete, ready-to-teach GCSE Foundation maths resit lesson for engineering learners.

Part of Maths for Engineering by Mo Squared: a 12-lesson series of GCSE Foundation maths taught through real engineering workshop tasks, for fabrication and welding, electrical and electronic, maintenance, and aerospace and automotive engineering groups. Written by an experienced FE maths resit teacher, so every question uses real jobs, prices and measurements.

What’s covered

• Part A: Reading steel rules, calipers and the unit ladder
• Part B: Comparing decimals and converting inches to mm
• Part C: Tolerances, upper and lower limits, QC tables and range

What’s included (4 files)

• Ready-to-teach PowerPoint (about 90 minutes): Recall, Starter, key words and facts, then Parts A, B and C, each with a visual method slide, I do, We do, 6 You Do mini-whiteboard questions and a timed task

• Exit tickets (two per page, with a confidence scale)
• Full teacher answers

Why teachers like it

• Click-by-click modelling: each click shows one step of the working with the matching part of the diagram
• Visuals everywhere: bar models, ratio tables, number lines and labelled diagrams
• Clickable answers that open full worked solutions
• Built-in differentiation: the You Do score tells learners whether to start on Bronze, Silver or Gold
• Realistic trade numbers, prices and rules; all questions are original and every answer has been checked twice

Ideal for GCSE maths resit (post-16), FE maths departments, vocational tutors embedding maths, and apprenticeship maths support.

Best used in Microsoft PowerPoint (desktop) so the click-by-click animations and answer links work.
