You are just two lessons away from having all of your multiplication facts mastered!
So far, you have learned how to multiply by two, three, four, five, six, seven, eight, ten, and eleven. Take a few minutes to review what you have learned and get your brain in math mode.
As always, if there is a set of multiplication facts that you still find to be challenging, go back and review those facts before moving on. Select the Related Lesson that you need to review from the right-hand sidebar.
When you have all of these multiplication facts memorized, continue with this lesson.
In this lesson, you will learn the nine times tables. There are a few fun tips and tricks you can use to remember the multiples of nine. Let's start by looking at the nine times tables on a multiplication table (below). Tell your teacher or parent what you observe when you look at the nine row and column:
The nine times tables display a unique pattern. If you do not see it in the multiplication table, look back at the question from the very beginning of the lesson.
You should notice that from one to ten, the ones place (the number all the way to the right) is constantly decreasing by one, while the tens place (the number to the left of the ones place) is constantly increasing by one:
There is also a fun trick you can do with your hands to help you learn the nine times tables (To see this method illustrated, go to the Elephango lesson found under Additional Resources in the right-hand sidebar.):
- Hold both of your hands in front of you, with your palms facing up.
- Each of your fingers represents a number from one to ten. Your thumb on your left hand is one, and your thumb on your right hand is ten.
- Let's say you wanted to find the answer to 9 x 3.
- With your fingers, count to three. When you get to the third finger (left middle finger), put that finger down. How many fingers are there to the left of the finger that is down? Tell your teacher or parent. This digit goes in the tens place of the product.
- How many fingers are there to the right of the finger that is down? Tell your teacher or parent. This digit goes in the ones place of the product.
- Did you get 27 for your answer? Try this technique to find the products for the following problems:
Show each of your answers to your teacher or parent, using your fingers. Add these tips and tricks to your foldable. You can write the information under the "9" flap.
Next, listen to this 9 Times Table Song Rap | Multiples of Nine by NUMBEROCK song two or three times. When you start to memorize the multiples of nine, say them along with the video:
