"Share a quantity equally and understand division as the opposite of multiplication."
A Today you'll learn
- Understand division as sharing equally
- Understand division as the opposite of multiplication
- Divide small numbers evenly
B Let's understand
Division means sharing a quantity into equal groups. If we have 12 sweets and share them equally among 3 friends, each friend gets 4 sweets. Division undoes multiplication: since 3 x 4 = 12, we know 12 divided by 3 is 4.
C See it step by step
Example 1: Worked example
- 12 ÷ 3 = 4 (12 shared into 3 equal groups gives 4 each)
Example 2: Worked example
- 20 ÷ 5 = 4 (because 5 x 4 = 20)
