# OCR A Level Computer Science H446 – Bubble Sort & Insertion Sort Interactive Simulator + Worksheet

Bring sorting algorithms to life with this interactive Bubble Sort and Insertion Sort Visualiser.

Designed for OCR A Level Computer Science H446 – Topic 2.3.1: Algorithms, this resource enables students to investigate how two important sorting algorithms organise data.

What can students explore?

Students can step through Bubble Sort and Insertion Sort, observe comparisons, swaps and shifts, and examine how the contents of an array change throughout the sorting process.

The step-by-step approach supports students who struggle to visualise algorithm execution and helps them compare different sorting techniques.

What’s included?

• Interactive offline HTML sorting simulator
• Printable student worksheet (PDF)
• Teacher guide with suggested lesson sequence (PDF)
• Teacher answers and extension guidance (PDF)
• Instructions and customisable licence template

Why use this resource?

Ideal for introducing sorting algorithms, demonstrating each stage of execution, supporting algorithm-tracing questions and developing computational thinking.

Suitable for A Level Computer Science lessons, revision, independent study and GCSE extension activities.
