Data sorting Good vs Bad KS2 / KS3 Introduction

A premium, zero-prep Computing lesson for KS2 focusing on Data Quality, Training Data, and Data Sorting. Perfect for non-specialists and neurodiverse classrooms.

Built on Cognitive Load Theory, this deck uses a clean, minimalist aesthetic (no visual clutter!) and a continuous illustrated narrative starring Max and Ellie the Persian cats to keep young learners fully engaged.

What’s Included:

7-Slide Presentation (PowerPoint & PDF): Includes a fully editable PPTX file and a fixed-format PDF. Explores the core concept of training data, the golden rule of “Garbage In, Garbage Out,” and visual classification tasks.

Independent Practice Task (Data Sorting & Matching): Students act as AI Quality Control Officers to sort “Good Data” (real treats) from “Bad Data” (buttons, pebbles, and socks) to fix the Feed-Bot’s dataset.

Printable Student Activity Sheet (PDF): A matching A4 “Data Sorting” worksheet featuring the illustrated fish, button, and pebble grid for students to circle and cross out.

Teacher-Proof Crib Sheet (Word): A complete, slide-by-slide script and answer key. You do not need to be a Computer Science specialist to teach this! The notes provide idiot-proof analogies (like Ellie knocking over the button jar) so any teacher or cover supervisor can deliver the lesson with total confidence.

Key Stage / Curriculum Focus:

KS2 Computing: Algorithms, data handling, recognising that programs execute by following precise instructions and evaluating digital data.

SEN / Neurodiverse Friendly: Low cognitive load, high contrast, uncluttered layouts, and visual step-by-step guidance.
