5. Patterns and Algebra

🟦 Definition

Patterns are repeated sequences of numbers, shapes, or objects.
Algebra starts with finding rules and missing parts in patterns.

➕ Algebra in Grade 2

We use symbols or boxes to show unknown numbers.
Example:
3 + ⬜ = 7 → The missing number is 4

🧠 Why It Matters

Patterns and algebra help us:

• Predict what comes next
  
  

• Find missing numbers
  
  

• Think logically and solve problems
