Your Amazing Digestive System | Explanation Writing Pack | Year 3/4

This two-week explanation writing unit explores the fascinating journey food takes through the body with the topic Your Amazing Digestive System. Fully resourced and aligned with Rosenshine’s Principles, this unit helps pupils develop their ability to write structured, clear explanations while deepening their understanding of human biology.

Pupils will learn about the organs of the digestive system, the process of breaking down food, and the different types of teeth that support digestion. Through carefully sequenced lessons, they will also improve their use of grammar features such as fronted adverbials, conjunctions, and expanded noun phrases—essential tools for effective explanation writing.

This pack includes:

• 10 complete writing lessons with learning objectives and success criteria
• A two-page WAGOLL (model text) with annotated teacher notes
• Over 110 editable teaching slides for modelling and shared writing
• 17 pupil worksheets with structured writing tasks

• Grammar focus: conjunctions, complex and compound sentences, adverbials
• Audio version of the WAGOLL for accessibility
• Dyslexia-friendly fonts and clear layout
• Retrieval activities, quick quizzes, and built-in assessment tasks

This resource is ideal for cross-curricular writing with science (Animals including Humans), whole class instruction, intervention groups, or independent writing assessment. Designed by a classroom teacher and tested in real schools, it saves time while helping pupils master explanation writing with confidence.
