Slide 1
Cracking the Code: Writing Pattern Rules
Year 8 Mathematics Finding patterns in numbers Writing rules as equations
2
Slide 2
Patterns Are Everywhere!
Walking steps: 3, 6, 9, 12, 15... What pattern do you notice? How many steps on Day 6? Patterns help us predict the future!

Slide 3
Hands-On Pattern Building
Use counters to build the pattern Work in pairs Fill in the table: Day (x) and Steps (y) What do you notice about the increase?

Slide 4
Writing the Rule as an Equation
The increase is always 3 x = day number, y = total steps The rule: y = 3x This means: total steps = 3 × day number

Slide 5
Practice Time: Find the Rules
Pattern 1: 2, 5, 8, 11, 14... Pattern 2: 4, 7, 10, 13, 16... Build with counters, fill the table, write the equation Use sentence starters: 'The rule is...' 'The increase is...'

Reflect and Share
Share one equation you wrote Explain your reasoning What was the trickiest part? How can patterns help us in real life?
