You find division facts by using your knowledge of multiplication tables to create related division number sentences.
Understanding Division Facts
Division facts are essentially the inverse of multiplication facts. They are crucial for building a strong foundation in mathematics and improving mental calculation skills. According to the reference provided, division facts are division number sentences related to times tables knowledge.
How to Generate Division Facts
Here's how you can identify and generate division facts:
- Start with a Multiplication Fact: Begin with a known multiplication fact, like 5 x 3 = 15.
- Create Two Division Facts: From this, you can create two division facts:
- 15 ÷ 3 = 5
- 15 ÷ 5 = 3
- Use the Times Table: Each times table creates a set of division facts. For example, the 5 times table provides:
- 5 ÷ 5 = 1
- 10 ÷ 5 = 2
- 15 ÷ 5 = 3
- 20 ÷ 5 = 4
- 25 ÷ 5 = 5, etc.
Examples of Division Facts
| Multiplication Fact | Related Division Facts |
|---|---|
| 2 x 4 = 8 | 8 ÷ 4 = 2 and 8 ÷ 2 = 4 |
| 3 x 6 = 18 | 18 ÷ 6 = 3 and 18 ÷ 3 = 6 |
| 7 x 8 = 56 | 56 ÷ 8 = 7 and 56 ÷ 7 = 8 |
| 9 x 5 = 45 | 45 ÷ 5 = 9 and 45 ÷ 9 = 5 |
| 10 x 10 = 100 | 100 ÷ 10 = 10 |
| 5 x 1 = 5 | 5 ÷ 1 = 5 and 5 ÷ 5 = 1 |
| 5 x 2 = 10 | 10 ÷ 2 = 5 and 10 ÷ 5 = 2 |
| 5 x 3 = 15 | 15 ÷ 3 = 5 and 15 ÷ 5 = 3 |
| 5 x 4 = 20 | 20 ÷ 4 = 5 and 20 ÷ 5 = 4 |
| 5 x 5 = 25 | 25 ÷ 5 = 5 |
| 5 x 10 = 50 | 50 ÷ 10 = 5 and 50 ÷ 5 = 10 |
How to Remember Division Facts
- Practice: Regular practice with multiplication tables and their corresponding division facts is essential.
- Use Flashcards: Flashcards can be a helpful tool for memorizing both multiplication and division facts.
- Think Backwards: When faced with a division problem, ask yourself, "What do I multiply this number by to get the other number?" For example, for 24 ÷ 6, think "What times 6 is 24?"
- Number Line: Using number line can be a great way to visualize division facts.
By understanding how division facts relate to multiplication tables, you can quickly and confidently solve division problems. Remember, division facts are division number sentences related to times tables knowledge, as stated in the reference.
