Everything you need to teach classifying organisms at KS3 — two complete resources, full answer keys, and no preparation required. This lesson pack covers the seven levels of classification, the vertebrate groups and using a classification key for students aged 11-14.

Classification means sorting living things into groups based on their features. A key is a list of questions, each with two possible answers, that leads you to the right group.

The main worksheet contains 16 questions worth 100 marks across three progressive sections: recall through multiple choice, true or false and a word bank task (30 marks); application through definitions, tables and using a key to sort animals (40 marks); and extended explanations including writing a key of their own (30 marks). The extension pack provides four enrichment activities — a 12-mark vocabulary matching exercise, a 30-mark challenge quiz, an 18-mark platypus case study and a rubric-assessed Teach It Back task. Each extension activity starts on its own page, so you can use as much or as little as you need. Full answer keys and detailed marking guidance are included for everything. Everything comes as a PDF and an editable Word file (DOCX).

Buying this bundle saves £1 compared to purchasing both resources separately (£3 + £3 = £6 individually, £5 as a pack).

Google Classroom ready.
