Hi! I'm Vidi. Let's learn Multiplication Facts (1-10) together — read with me, then play the games to win a ⭐!
🔵Multiplication Fluency (1x1 to 10x10)
Multiplication is repeated addition. Knowing your times tables up to 10x10 is essential for all higher maths.
Key facts to memorize:
- Any number x 1 = itself (7x1=7)
- Any number x 10 = add a 0 (6x10=60)
- 9x rule: digits of product sum to 9 (9x3=27, 2+7=9)
- 5x rule: ends in 0 or 5 (5x7=35)
👀 See a worked example
7 x 8 = ?
56. 7x8 is one of the trickier facts. Remember: 56 = 7x8 (5,6,7,8 — the digits go in order!).
9 x 6 = ?
54. Use the 9s trick: 9x6=54, and 5+4=9. Always works for 9 times table.
4 x 9 = ?
36. 4x9 = 36. Check: 3+6=9. Correct!
🤖 Vidi's Key Points
- Practice all facts from 1x1 to 10x10 daily.
- 9x trick: digits of product always sum to 9.
- 5x: always ends in 0 or 5.
🟢Commutative Property of Multiplication
The commutative property means: order does not matter in multiplication.
a x b = b x a
This is useful because you only need to learn half the times table — if you know 7x8=56, you also know 8x7=56.
👀 See a worked example
5 x 6 = 30. What is 6 x 5?
6 x 5 = 30. Commutative property: switching the order gives the same answer.
Write another fact related to 8 x 3 = 24.
3 x 8 = 24. Flip the two numbers — the product stays the same.
Is 9 x 7 = 7 x 9?
Yes. Both equal 63. Commutative property always works for multiplication.
🤖 Vidi's Key Points
- a x b = b x a always. Order never changes the product.
- Knowing 7x8=56 means you also know 8x7=56 for free.
- This halves the number of multiplication facts you need to memorize.
🟣Missing Factor Problems
When you know the product (answer) and one factor, you can find the missing factor using division or the times table.
Example: ___ x 6 = 24. Think: what times 6 equals 24? 4 x 6 = 24, so the answer is 4.
👀 See a worked example
___ x 7 = 35
Think: 7 x what = 35? Count by 7s: 7,14,21,28,35. Five 7s = 35. Answer: 5. Or: 35/7 = 5.
9 x ___ = 54
54 / 9 = 6. Or count by 9s until you reach 54: 9,18,27,36,45,54 — that is 6 steps. Answer: 6.
___ x 8 = 72
72 / 8 = 9. Check: 9 x 8 = 72. Answer: 9.
🤖 Vidi's Key Points
- Missing factor = product / known factor.
- Use your times table knowledge to find the missing number.
- Always check: missing factor x known factor = product.
