Multiplication Patterns You Should Know

Fast multiplication is not about memorizing random facts forever. It is about recognizing structure. ## Pattern 1: Break numbers apart Example: 14 × 6 Think: 10 × 6 = 60 4 × 6 = 24 60 + 24 = 84 This works because multiplication distributes nicely. ## Pattern 2: Multiply by 5 using half of 10 Example: 18 × 5 Think: 18 × 10 = 180 Half of 180 = 90 So: 18 × 5 = 90 ## Pattern 3: Multiply by 9 using 10 minus 1 Example: 7 × 9 Think: 7 × 10 = 70 70 - 7 = 63 This is often faster than recalling the fact directly. ## Pattern 4: Use doubles Example: 16 × 4 Think: 16 × 2 = 32 32 × 2 = 64 Repeated doubling is very useful. ## Pattern 5: Split harder problems into easier ones Example: 12 × 13 Think: 12 × 10 = 120 12 × 3 = 36 120 + 36 = 156 ## Practice ideas Try these mentally: 13 × 7 18 × 5 9 × 6 14 × 8 12 × 12 ## What to remember Strong multiplication comes from: - knowing your base facts - breaking numbers apart - using easy patterns - staying calm under time pressure The more patterns you see, the faster multiplication becomes.
