KS3 Percentages Worksheets

These resources cover Year 7, Year 8, and Year 9, spanning the entire KS3 phase. Year 7 students typically begin with finding percentages using the 10% or 1% method, whilst also converting between percentages, fractions, and decimals. By Year 8, most students tackle percentage change problems and begin expressing quantities as percentages of each other.

Year 9 work extends to reverse percentages and compound interest problems, where students must work systematically through multiple percentage changes. Teachers often notice that the jump to reverse percentages catches students out because it requires them to think about the problem structure differently rather than just applying a memorised procedure. This progression ensures students develop both procedural fluency and conceptual understanding before facing GCSE assessments.

The worksheets work well for differentiated practice because they build systematically from basic percentage calculations to more complex applications. Teachers can assign specific sections based on prior assessment, allowing students who grasp concepts quickly to move ahead whilst others consolidate fundamentals. The included answer sheets enable immediate self-checking, which helps students identify errors in their method before misconceptions become embedded.

Many teachers use these resources for retrieval practice at lesson starts, targeted intervention sessions, or as structured homework that parents can support using the answers provided. They're particularly effective for exam revision because they mirror the question styles and progression that appear in Key Stage 3 tests and early GCSE practice papers. Some teachers also find them useful for paired work, where students check each other's methods using the answer sheets, encouraging mathematical discussion about why particular approaches work.
