7's Table Trick
The 7's Table Trick is a method for memorizing the 7 times table. It is a visual representation of the multiples of 7, and it can be helpful for people who learn best visually or kinesthetically.
To create the 7's Table Trick, start by drawing a 3x3 grid. In the top left corner, write the number 0. In the next box, write the number 1. In the third box, write the number 2. In the next row, write the number 2 in the first box. In the next box, write the number 3. In the third box, write the number 4. In the bottom row, write the number 4 in the first box. In the next box, write the number 5. In the third box, write the number 6. Finally, write the number 7 next to the zero in the top left corner.
| 0 | 1 | 2 |
| 2 | 3 | 4 |
| 4 | 5 | 6 |
The 7's Table Trick works as follows:
- The ones digits of the multiples of 7 are the numbers from 0 to 9, written in order from top right to bottom left.
- The tens digits of the multiples of 7 are the numbers from 0 to 6, written in order from top left to bottom right.
For example, to find the product of 7 x 4, look at the fourth box in the second row. The ones digit is 8 and the tens digit is 2, so 7 x 4 = 28.
To find the product of 7 x 9, look at the bottom right box. The ones digit is 9 and the tens digit is 6, so 7 x 9 = 63.
The 7's Table Trick can be helpful for people of all ages and learning styles. It is a quick and easy way to memorize the 7 times table, and it can be used to solve multiplication problems quickly and easily.
The reason there are two fours and a zero in the 7's Table Trick is because the multiples of 7 follow a specific pattern. The ones digits of the multiples of 7 repeat every nine numbers, and the tens digits of the multiples of 7 repeat every six numbers. This pattern can be seen in the following table:
| Multiple | Ones digit | Tens digit |
|---|---|---|
| 7 x 1 | 7 | 0 |
| 7 x 2 | 4 | 1 |
| 7 x 3 | 1 | 2 |
| 7 x 4 | 8 | 2 |
| 7 x 5 | 5 | 3 |
| 7 x 6 | 2 | 4 |
| 7 x 7 | 9 | 4 |
| 7 x 8 | 6 | 5 |
| 7 x 9 | 3 | 6 |
| 7 x 10 | 0 | 7 |
As you can see, the ones digits of the multiples of 7 repeat every nine numbers, and the tens digits of the multiples of 7 repeat every six numbers. This is why there are two fours and a zero in the 7's Table Trick.
