Meet the Math Facts: Multiplication & Division

Understanding 5 x 9 = 45

Hey there! Today, we’re going to learn about a fun math fact: 5 times 9 equals 45. Let’s explore what this means and how you can remember it easily!

What Does 5 x 9 Mean?

When we say 5 times 9, we’re talking about adding the number 9 together five times. So, it’s like saying 9 + 9 + 9 + 9 + 9. If you add all those nines together, you’ll get 45!

Counting by Nines

Let’s try counting by nines to see how we get to 45:

  • 9
  • 18
  • 27
  • 36
  • 45

See? When you count by nines, the fifth number you say is 45. That’s why 5 times 9 equals 45!

Fun Ways to Remember

Here are some fun ways to remember that 5 times 9 equals 45:

  • Think of your hand with five fingers. Each finger is like a group of 9, and together they make 45!
  • Sing a little song or rhyme about 5 times 9 equals 45 to help it stick in your mind.

Practice Makes Perfect

Try practicing this math fact with your friends or family. You can quiz each other or make up a game to see who can remember it the fastest!

Keep Exploring!

Now that you know 5 times 9 equals 45, try learning other multiplication facts. The more you practice, the better you’ll get at math!

Happy learning!

  • Can you think of something in your life that comes in groups of nine? How would you use multiplication to find out how many there are in total if you have five groups?
  • When you learned that 5 times 9 equals 45, did it remind you of any other math facts you know? How do you remember those facts?
  • Imagine you are teaching a friend how to remember that 5 times 9 equals 45. What fun or creative way would you use to help them remember this math fact?
  1. Finger Multiplication Magic: Use your fingers to explore multiplication! Hold up both hands and imagine each finger represents a number. For 5 x 9, fold down the fifth finger on your left hand. Count the fingers to the left of the folded finger (4) and the fingers to the right (5). Put them together, and you get 45! Try this with other numbers to see how it works.

  2. Number Hunt: Go on a number hunt around your house or classroom. Look for groups of 9 items, like 9 pencils or 9 blocks. Count how many groups of 9 you can find. How many groups do you need to make 45? Can you find exactly 5 groups of 9?

  3. Story Time with Numbers: Create a short story or draw a picture about a character who loves the number 9. Maybe they have 9 pets or collect 9 different things. How does their collection grow when they add more groups of 9? Share your story or drawing with a friend or family member.
