Percentages Unlocked – Diagnostic, Lessons & Two-Level Word Problems | GCSE & IGCSE 0580

Can your students do the maths but get lost in the wording?

Percentages Unlocked teaches percentages and the language of percentage problems together. Every word problem comes in two versions with identical numbers: Standard English and Plain English. If a student solves the Plain version but not the Standard one, you know the barrier is language, not maths.

What’s included

Diagnostic check: 12 multiple-choice questions. Every wrong answer is linked to a named misconception, with a follow-up question to check it is fixed.
Two ready-to-teach lessons (37 slides): percentages of amounts; multipliers, percentage change and reverse percentages. Click-to-reveal answers, vote questions that target common errors, a bar-model reverse percentage slide, and a teacher script in the notes of every slide.
Practice booklet: 15 Bronze (fluency), 15 Silver (two-step) and 10 Gold (problem-solving) questions, each marked calculator or non-calculator.
12 word problems in Standard English and the same 12 in Plain English.
Word-Problem Decoder: a 4-step routine with sentence frames and a “which method?” signal-word table.
Vocabulary mat: 16 key words with meanings, examples and a column for students’ own language.
Four exit tickets (two per lesson).
Fully worked answers to every question.
Teacher Guide: lesson plans with timings, curriculum map, diagnostic follow-up table and advice on using the two language levels.
