When we multiply by 9, we can use a simple trick to make it easier. First, let’s look at some examples:
Now, let’s try saying the answers together. Ready? Go!
Now it’s your turn! Can you say the answers on your own?
Here’s a neat trick to help you multiply by 9 easily. Take the number you want to multiply by 9, add a zero to it, and then subtract the original number.
Let’s try it with 9 x 4:
So, 9 x 4 is 36. Isn’t that cool? Try it with other numbers and see how it works!
Keep practicing these tricks, and soon you’ll be a multiplication master! Remember, learning can be fun and exciting. Say “Yes, I can!” and enjoy your math adventures!
Finger Trick for Multiplying by 9: Use your fingers to help you multiply by 9. Hold out both hands in front of you. To find 9 times a number, like 9 x 3, fold down the third finger from the left. Count the fingers to the left of the folded finger (2) and the fingers to the right (7). Put them together, and you get 27! Try this trick with other numbers from 1 to 10 and see if you can find the pattern.
Number Patterns with 9: Write down the multiplication table for 9 from 9 x 1 to 9 x 10. Look closely at the answers. Do you notice a pattern in the digits? Hint: The digits in each answer add up to 9! For example, in 9 x 3 = 27, 2 + 7 = 9. Try to find this pattern in all the answers and share your discovery with a friend or family member.
Real-Life Multiplication Hunt: Go on a multiplication hunt around your house or neighborhood. Look for groups of items that you can multiply by 9. For example, if you see 9 apples in a basket, you can think about how many apples there would be in 2 baskets (9 x 2). Write down your findings and draw pictures to show your multiplication stories.
