Lesson Plan - Get It!
Kim is buying Christmas gifts for her three best friends. She plans to spend $8 on each friend.
- How much money does she need to take out of the bank to go shopping?
- What numerical problem did you create to solve the word problem?
Share your answer with a teacher or parent. If you said 3 x 8 = $24, you are correct!
- You have already studied the three times tables, so what times tables do you think you will study in this lesson?
Get ready to learn the eight times tables!
- Do you realize you have learned more than 100 multiplication facts?
Wow! You should be feeling pretty good! Before you start learning another set of multiplication facts, let's review what you have already learned:
If you found any of those problems to be a challenge, you may need to go back and review. Select the Related Lesson, from the list in the right-hand sidebar, for the times tables you still find to be challenging. Review that lesson thoroughly. Make sure to re-listen to the song, read over any tips and tricks, and replay any games.
When you are confident that you have mastered all of these multiplication facts, continue with this lesson.
In this lesson, you will learn multiples of eight. Since you have already learned so many multiplication facts, you already know how to solve most multiplication problems with eight.
To start learning multiples of eight, complete the chart below by skip-counting by eight. If you are uncertain what the next number should be, use the dot method to find out.
To use the dot method, draw eight dots on your paper. When you are counting, put your pencil on each dot to help you count.
For example, let's say you get to 24 and do not know what 8 x 4 equals. Put your pencil on the first dot and say 25 out loud. Then, put your pencil on the next dot and say 26 out loud. Continue this process, using each dot. When you say the number at the last dot, you have found the answer to 8 x 4.
Use the image as an example:
Have your teacher or parent check your chart, then look at the multiplication table below. The eight times tables have been highlighted. Make a list of patterns, repeated numbers, or other observations. Share your list with a teacher or parent:
When learning the eight times tables, there are a few things you should notice.
- First, multiples of eight do reveal a pattern. The ones place, or the place all the way to the right, has a repeating pattern of 8, 6, 4, 2, 0. Did you make that observation?
- The second thing to know about the eight times tables is a little more challenging to notice. Any time the last digit in the product (the ones place) is 8, 4, or 0, the second-to-last digit (the tens place) is an even number.
- Also, any time the last digit in the product (the ones place) is 6 or 2, the second to last digit (the tens place) is an odd number.
Look at the multiplication table again with your parent or teacher. Look for examples of the above observations in the highlighted row and column. Remember to add these tips to the foldable you have been creating throughout this series.
Continue reviewing multiples of eight by listening to the 8 Times Table Song | Multiples of 8 by NUMBEROCK song. Listen to the song two or three times to help the multiples stick in your head. Say the multiples of eight along with the video:
After you have listened to the song a few times, see if you can remember the lyrics by writing them on a piece of paper. If you forget any lyrics, replay the video to help you.
Then, move on to the Got It? section to practice solving multiplication problems with eight.
