Learning Objectives

By the end of this lesson, students will be able to:

• Identify patterns in sequences of numbers.
• Describe rules governing number patterns verbally and in writing.
• Use colours to visually represent relationships in number sequences.

---

Materials Needed

• Large coloured number cards (multiple sets).
• Mini whiteboards and markers.
• Multi-coloured counters or cubes.
• Printed worksheets with pattern problems.
• A visualiser (if available) to display students' work.

Lesson Structure

1. Introduction – The Colour Code (10 minutes)

Begin by showing a set of numbers on the board using large, bold, and coloured numbers without initially explaining their connection (e.g., 2, 4, 8, 16 in green, and 5, 10, 15, 20 in red).

Engagement Activity:

• Ask students: "What do you notice about the numbers? Why might they be grouped by colour?"
• Facilitate a short discussion where students hypothesise the patterns.
• Reveal that today’s lesson is all about spotting and understanding number patterns using colours!

2. Guided Exploration – Cracking the Code (15 minutes)

Introduce different types of number patterns:

1. Doubling Sequences: 2, 4, 8, 16…
2. Multiplication Sequences: 3, 6, 9, 12…
3. Odd & Even Patterns:
4. Fibonacci Sequences (challenge level for higher-attaining students).

Activity:

• Distribute coloured number cards randomly to students.
• Call out a rule (e.g., "Find numbers that double each time!") and students must group themselves by colour representing the correct pattern.
• Reinforce key learning with mini whiteboards, allowing small groups to jot down the rule behind their sequence.

3. Independent Practice – The Colour Race! (15 minutes)

Paired Activity:

• Hand out printed worksheets.
• Each question includes incomplete number patterns that must be solved and coloured in correctly.
• Example:
  • 3, 6, __, 12, __ (students colour these in a matching scheme).
  • 4, 8, 12, __, __ (students complete & colour).
• Pairs work through the problems, developing reasoning skills by justifying their choices.

Differentiation:

• Support: Provide scaffolded number patterns with hints.
• Extension: Ask higher-ability students to create their own unique patterns with new colours assigned.

4. Whole-Class Challenge – Colour Grid (10 minutes)

A large grid is displayed on the board (or drawn on large paper). Each row corresponds to a different number pattern but with missing numbers.

Game:

• Students raise hands to contribute missing numbers and explain the pattern rule.
• If correct, they add a coloured counter to the board.

The goal is to complete the challenge as a class by filling in the number patterns correctly.

---

5. Reflection & Plenary – What’s the Rule? (10 minutes)

• Display three new number sequences and ask:
  "Can you write the rule for each one?"
• Students discuss in pairs, write their answers using coloured mini whiteboards, and share their reasoning.
• Reinforce how colours helped them visualise number patterns.

Final Thought:

• "Where do we see number patterns in real life?" (E.g., music beats, nature, technology).
• Allow a few students to share their ideas, ensuring connections beyond maths lessons.

---

Assessment & Evaluation

Formative:

• Observation during activities (Are students identifying and explaining patterns correctly?).
• Whiteboard responses during pair work and whole-class discussions.

Summative:

• Analysis of completed worksheets to ensure students applied correct patterns and colours.
• Extension task for students to invent their own patterns with explanations.

Homework (Optional)

Students create their own colourful number puzzle, where a secret pattern determines the sequence. They swap with a partner to solve the next day!
