Multiply by 3
Multiplication is adding the same number repeatedly.
To multiply by 3, you add a number to itself 3 times.
What’s 2 × 3?
You can draw equal groups to help figure it out.
2 × 3 is a shortcut for writing:
2 + 2 + 2 = 6
Tip: Do skip-counting in your head to figure it out:
2, 4, 6

Multiply by 10
Any time we multiply a whole number by 10 we’re gonna keep the original number and simply add a zero to the end.
1 × 10 = 10
2 × 10 = 20
3 × 10 = 30
4 × 10 = 40
5 × 10 = 50

- 12 × 10 = 120
💡 Multiplying a number by 10 is the same as adding a number to itself 10 times.
3 x 10 = ?
To figure out the answer, we can do repeated addition:
3 + 3 + 3 + 3 + 3 + 3 + 3 + 3 + 3 + 3 =30 😅
| equal to 25 | greater than 25 | less than 25 |
| 5×5 | 10×5 | 5×4 |
| 10×4 | 3×3 |
| equal to 50 | greater than 50 | less than 50 |
| 10×5 | 10×6 | 5×5 |
| 10×7 | 5×4 |
