Scaffolded Algorithms Work Booklet: OCR GCSE (J277) (Lower Ability)

Standalone OCR GCSE algorithms work booklet written in OCR Exam Reference Language: 9 lessons, worked examples, extension tasks, exam-style questions and full answers.

A 58-page booklet that students can work through on their own or alongside your lessons. Every lesson uses the same six colour-coded pages, so students always know what comes next. It suits normal lessons, cover lessons, homework, catch-up and revision.

9 lessons

Computational Thinking (decomposition, abstraction, algorithmic thinking)
Flowcharts
Writing Algorithms (sequence, selection, iteration)
Trace Tables
Linear Search
Binary Search
Bubble Sort
Merge Sort
Insertion Sort

Every lesson has six pages

Learn: “Today I will…” goals, a “What you need to know” explanation with the key terms in bold, and a key words table
Example: a “Watch me” worked example with numbered notes, the two most common mistakes, and an exam tip
Practise: fill the gaps from a word bank, choose the answer (tick one box), and finish the code, flowchart or trace table
Apply: put the steps or lines of code in order, then “Have a go!” with a tick-box checklist of steps and a hint
Review: spot the mistake, finish a sentence to explain the idea, match the key words, and a “How did I do?” traffic light
Extend: extra independent practice: four quick-fire questions, an exam-style question with marks, and a challenge task. Ideal for homework, early finishers and revision.

Written for OCR J277

All code uses OCR Exam Reference Language (=, ==, if…then…endif, for…next, while…endwhile, .length)
Covers all three sorting algorithms OCR requires: bubble sort, merge sort and insertion sort

Designed so students can learn independently

Each topic is explained in short, clear sentences before students attempt any tasks
Searches and sorts are shown step by step with highlighted number boxes
Flowcharts are drawn with the correct symbols
Trace tables are completed row by row
“Spot the mistake” tasks cover the errors students really make, such as starting a loop at index 1, binary searching an unsorted list, or stopping a bubble sort after one pass
9 original exam-style questions, with the answer booklet showing where each mark is earned
Key word glossary and a “What can I do now?” checklist at the back

What’s included
