ClassX Video Lessons Grade Grade 2 Adding 2-Digit Numbers with Base 10 Blocks | Place Value for Kids | Khan Academy Kids
Hey there! Today, we’re going to learn about adding big numbers with the help of Superpack. It’s going to be fun and easy, so let’s get started!
First, let’s look at the numbers 30 and 23. To make it simple, we can use rods and blocks. Each rod is made up of 10 blocks. So, let’s see how we can use them to add these numbers.
For the number 30, we have three rods. Since each rod is 10 blocks, three rods make 30 blocks in total.
Now, let’s look at the number 23. We have two rods, which make 20 blocks, and three extra blocks. So, 23 is made up of two rods and three blocks.
When we add 30 and 23, we combine the rods and blocks. We have three rods from 30 and two rods from 23. That makes a total of five rods, which is 50 blocks.
Don’t forget the extra three blocks from 23. So, when we add everything together, we get 53 blocks in total.
The most important thing to learn here is how to break down big numbers into smaller parts using rods and blocks. This makes it easier to add them together. Remember, five rods and three blocks make 53!
Now you know how to add big numbers using rods and blocks, just like Superpack. Keep practicing, and you’ll get even better at it!
Build Your Own Number: Gather some small objects like sticks or straws to represent rods and small blocks or buttons to represent single blocks. Try creating different numbers by combining rods and blocks. For example, make the number 45 using four rods and five blocks. Can you make the number 67? How many rods and blocks do you need?
Number Hunt: Look around your home or classroom for numbers. When you find a number, try to break it down into rods and blocks in your mind. For example, if you see the number 82, think about how many rods and blocks it would take to make that number. Share your findings with a friend or family member and see if they can guess the number you are thinking of!
Story Time with Numbers: Create a short story where the characters are numbers. For example, “Once upon a time, there were two numbers, 40 and 15. They decided to go on an adventure together. When they combined their strengths, they became 55!” Draw pictures to go along with your story and share it with your class or family.
