Identifying Numeric &
Geometric Patterns

With your kind teacher Mrs. Brenda ❤️

Hi my pattern-hunting superstars! 🌟

Patterns are all around us — in numbers, shapes, nature, and even our daily routines! Today we’ll learn how to spot, describe, and extend both numeric and geometric patterns. This is the beginning of algebra and it’s so much fun! Let’s become pattern detectives together! 🔍

1. Numeric Patterns

These are patterns made with numbers. We look for the rule that connects them.

Example 1: 3, 6, 9, 12, 15, ...
Rule: Add 3 each time → Next numbers: 18, 21, 24
Example 2: 2, 4, 8, 16, 32, ...
Rule: Multiply by 2 each time → Next: 64, 128
Example 3 (Growing & Shrinking): 20, 17, 14, 11, ...
Rule: Subtract 3 each time

2. Geometric Patterns

These are patterns made with shapes, colours, or sizes that repeat or grow.

Example: Triangle → Square → Pentagon → Hexagon ...
Rule: Number of sides increases by 1 each time

3. Input-Output Tables

Input → Output

1 → 5
2 → 8
3 → 11
4 → 14

Rule: Multiply by 3 and add 2 → Output = 3×Input + 2

4. Let’s Practice Together! 🎉

Question 1:

What comes next? 5, 10, 15, 20, __

Rule: Add 5 → 25 ⭐

Question 2:

What is the rule? 4, 8, 16, 32, 64...

Multiply by 2 each time ⭐

Question 3:

Draw or describe the next shape: △ □ △ □ △ __

□ (alternating triangle and square) ⭐

Question 4:

Input: 1, 2, 3, 4 → Output: 5, 8, 11, 14. What is the rule?

Multiply by 3 and add 2 ⭐

Question 5 (Real Life):

A plant grows 2 cm every week. How tall will it be after 5 weeks if it starts at 3 cm?

Rule: Add 2 each week → 3 + (2×5) = 13 cm ⭐

You are a Pattern Detective! 🏆🔍

Wonderful work today! You can now spot, describe, and extend numeric and geometric patterns.

Patterns are the secret language of math — keep looking for them everywhere!

I’m so proud of you,

Keep exploring the world of patterns,
Mrs. Brenda ❤️
