Audio:

There are 12 kids that live on Grove Street. Mrs. Carver wants to bake muffins for each of the kids in the neighborhood. She prepares a bag with five muffins for each child on the street.

• How many muffins did Mrs. Carver bake?

This final word problem is a tough one!

• What problem did you create?
• What product did you find?

• Did you get 12 x 5 = 60?

That is correct! Now, it's time to learn the final set of multiplication facts. By the end of this lesson, you will be a Times Tables Superstar!

Congratulations! You have made it to the final lesson of the Times Tables series or Related Lessons!

As of right now, you should know how to multiply by two, three, four, five, six, seven, eight, nine, ten, and eleven.

Let's review the multiplication tables you have learned to this point:

As always, if you notice there is a set of times tables you still find difficult, go back and review that Related Lesson (right-hand sidebar) before moving forward with this lesson.

• Are you feeling confident with all the multiplication facts to 11?

Great! Let's get started on 12!

In this final lesson, you will learn the twelve times tables. Multiples of twelve can be challenging, even for some adults.

Luckily, you have already seen every multiplication fact — except 12 x 12 — in the previous lessons throughout this series. That means the only multiplication fact you need to memorize in this lesson is 12 x 12.

• Do you know the answer?

If you are not sure, use the dot method to find the answer.

1. If you do not remember how to use the dot method, draw a row with 12 dots on a piece of paper.
2. Put your pencil on the first dot and say "1" out loud.
3. Then, put your pencil on the second dot and say "2" out loud.
4. When you get to the last dot, you should say "12." You have found the answer to 12 x 1.
5. Go back to the beginning of your row.
6. Put your pencil on the first dot and say "13." Each time you get to the end of the row, you have found another multiple of 12!

Now, look at the multiplication chart below. The multiples of 12 have been highlighted. Write down any notable observations that you make. Make sure to include any patterns or repeated numbers that you see:

There are not any patterns or repeated numbers you can use to help you remember the 12 times tables, but you can use easier times tables to help you find the product.

If you know the ten times tables and the two times tables, then you can figure out the 12 times tables. Just multiply the number by ten, and keep that number in your head. Then multiply the number by two. Next, simply add the two products together and you have your answer!

For example, to find 12 x 4:

• 10 x 4 = 40
• 2 x 4 = 8
• 40 + 8 = 48, so
• 12 x 4 = 48

Your turn to try. Use the same method to find the product of 12 x 7:

• 10 x 7 = 70
• 2 x 7 = 14
• 70 + 14 = 84, so
• 12 x 7 = 84

If you ever get stuck on a multiplication problem with 12, use this strategy and you will always get the correct answer.

Now, you try! Use this strategy to find the product of 12 x 9 and 12 x 6. When you are finished, check your work:

After you have practiced, add this final tip to your foldable under the "12" flap.

Have a teacher or parent quiz you on the strategies by saying a number. Then, you can respond by stating any tips or tricks associated with remembering the times tables for that number.

Now it's time to listen to this Multiplication Table Song // 12 Times Table by Math Max song two or three times to help you memorize the multiples of 12:

Move on to the Got It? section to play games and practice solving problems with 12!
