Multiplication as Repeated Addition & Equal Groups
Welcome to multiplication! Multiplication is simply a fast, magical way to add equal groups together.
Group 1
+
Group 2
+
Group 3
3 groups of 2
3 × 2 = 6
Multiplication: Repeated addition of equal groups (2 + 2 + 2 = 3 × 2 = 6).
1. What is Repeated Addition?
When you have 4 plates, and each plate has 3 cookies:
3 + 3 + 3 + 3 = 12 cookies.
Instead of writing 3 four times, we write: 4 × 3 = 12 (read as '4 times 3 equals 12').
The Symbol: The '×' sign means 'groups of' or 'times'.
2. Groups of Objects
5 bicycles each have 2 wheels. That is 5 groups of 2: 2 + 2 + 2 + 2 + 2 = 10 wheels. Or simply: 5 × 2 = 10 wheels!
Remember: Any number multiplied by 1 is itself (7 × 1 = 7). Any number multiplied by 0 is 0!
💡 Key Learning Takeaways
- Multiplication is repeated addition of equal groups.
- 4 × 3 means 4 groups of 3.
- The × symbol means 'times' or 'groups of'.
