Introduction
Have you ever seen numbers that seem to follow a secret rule? Maybe you noticed patterns when you skip-count or when you measure time. In this WebQuest, you will become a Number Detective!
You will investigate different number sequences, discover their hidden rules, and create your own number pattern to challenge your classmates.
Task
You will:
• Explore examples of number sequences.
• Identify the rules used in number patterns.
• Create your number sequence puzzle.
• Find real-life number patterns in Jamaica.
• Present your discoveries through a poster, PowerPoint, or short skit.
Process
Step 1: Learn about Number Sequences
• Watch this short video on number patterns:

• Read pages 34–38 of your Mathematics textbook (NSC Grade 5) on Patterns and Sequences.
• Answer these questions in your notebook:
• What is a number sequence?
• What is a rule in a sequence?
Step 2: Solve These Sequences
Look at these sequences:
1. 2, 4, 6, 8, __, __
2. 15, 13, 11, 9, __, __
3. 5, 10, 20, 40, __, __
• Find the rule.
• Predict the next two numbers.
Step 3: Create Your Sequence
• Create a number sequence using your own rule.
• Write the first five numbers of your sequence.
• Prepare three clues to help your classmates guess the rule.
Example:
Sequence: 10, 15, 20, 25, 30
Rule: Add 5 each time.
Step 4: Discover Patterns in Real Life
Look around your community or at home.
Find two examples of number patterns. These can be:
• Tiles on a house
• Steps on a staircase
• Beats in a reggae song
• Cricket scores
Take a picture, make a drawing, or describe the pattern you find.
Step 5: Present Your Work
Choose one way to present:
• A poster
• A short digital slideshow
• A 2-minute skit acting as a Number Detective
