ClassX Video Lessons Youtube Channel TutoringHour Subtraction on a Number Line | Let’s Go Hippity-Hoppity!
Hello, friend! Are you ready to learn subtraction in a fun way? Today, we are going to use a number line to help us subtract numbers. We have two cute friends, Skittles the birdie and Mr. Snowball, to help us hop along the number line!
Our first problem is 5 minus 3. Imagine a number line with numbers from 0 to 10. Skittles, our little birdie, is sitting on the number 5. She needs to hop backward three times. Let’s count together: 1, 2, and 3. Now, Skittles is on the number 2. So, 5 minus 3 equals 2. Great job!
Our next problem is 9 minus 4. Mr. Snowball is standing on the number 9. He needs to hop backward four times. Let’s count his hops: 1, 2, 3, and 4. Mr. Snowball lands on the number 5. So, 9 minus 4 equals 5. Well done!
Now, let’s find the difference between 15 and 8. We need a longer number line, so let’s imagine it goes up to 20. Start at 15 and hop backward 8 times: 1, 2, 3, 4, 5, 6, 7, and 8. We land on the number 7. So, 15 minus 8 equals 7. That was quick!
Now it’s your turn to try! You can use a number line to practice subtracting numbers. If you want to learn more and have fun, visit tutoringhour.com. If you liked this lesson, tell your friends about it!
Thanks for learning with us! Keep practicing and have fun hopping on the number line!
Number Line Hopscotch: Create a number line on the ground using chalk or tape, with numbers from 0 to 20. Use small toys or stones as markers. Ask the children to choose a subtraction problem, like 7 minus 2. Have them place their marker on the starting number (7) and hop backward the number of spaces they need to subtract (2 spaces). Encourage them to say the numbers out loud as they hop. This will help them visualize subtraction and make it a fun physical activity.
Subtraction Story Time: Encourage the children to create a short story using subtraction. For example, “Once upon a time, there were 10 apples on a tree. Three apples fell down. How many apples are left on the tree?” Ask them to draw pictures to illustrate their story and use a number line to solve the subtraction problem. This activity helps them connect subtraction to real-life scenarios and enhances their creativity.
Subtraction Detective: Give each child a small notebook and pencil. Ask them to be “Subtraction Detectives” for a day. They should look for examples of subtraction in their daily life, such as noticing how many cookies are left after some are eaten or how many toys are left after sharing with a friend. At the end of the day, have them share their findings with the class. This encourages them to observe and apply subtraction in everyday situations.
**Sanitized Transcript:**
Hello and welcome to Tutoring Hour! In this video, we’ll show you how to use a number line to subtract numbers within 20. Get ready to hop your way with Skittles and Snowball!
Our first problem is 5 minus 3. We have our number line and Skittles, our little birdie perched on the number 5. She needs to hop backward three times: 1, 2, and 3. Now Skittles is on the number 2. So, 5 minus 3 is 2. Great job!
Let’s move on to our next problem: 9 minus 4. We’ll bring our number line. We have Mr. Snowball on the number 9. He needs to hop backward four times: 1, 2, 3, and 4. Mr. Snowball has landed on the number 5. And that is our answer!
Now, let’s find the difference between 15 and 8. Here is our number line. It doesn’t have the number 15, so let’s extend our number line to 20. Now we’ll start with 15 and draw 8 hops backward: 1, 2, 3, 4, 5, 6, 7, and 8. We have landed on 7. So, 15 minus 8 is 7. That was pretty quick!
