How Many Times?
Introduction to Multiplication, Repeated Addition, and Tables
Multiplication is a fast way to add! We explore the concept of **repeated addition**, understand how the 'times' symbol works, and begin learning the basics of multiplication tables.

Observation:
Multiplication is the process of adding the same number to itself a certain number of times. It is much faster than traditional addition when dealing with large, repeated sums.
The Power of Repeated Addition
Concept of Multiplication:
Multiplication is a quick way to find the **total** when you have equal groups.
| Example | Operation | Read As |
|---|---|---|
| $4 + 4 + 4 + 4 + 4 = 20$ | $5 \times 4 = 20$ | 5 groups of 4 equals 20 |
| $6 + 6 + 6 = 18$ | $3 \times 6 = 18$ | 3 times 6 equals 18 |
Multiplication Terms:
- **Multiplier:** The number of groups (e.g., the 5 in $5 \times 4$).
- **Multiplicand:** The number in each group (e.g., the 4 in $5 \times 4$).
- **Product:** The result of the multiplication (e.g., the 20 in $5 \times 4 = 20$).
- **Symbol:** The multiplication symbol is '$\times$' (read as "times").
Learning Tables:
Multiplication tables are essentially memorized lists of repeated addition facts (e.g., the 'Table of 2' is just $2+2, 2+2+2, 2+2+2+2$, etc.). Knowing these makes calculations instant.
