Addition

Hello dear children!  Today, we’re going to learn something really exciting and useful — Addition! You’ve already learned how to add 3-digit numbers, right? Great job! Now, we’re going to level up and learn how to add 4-digit numbers — both with and without carrying. Don’t worry, I’ll be with you every step of the way! What is Addition? Addition means putting things together. When we add, we’re simply finding how many in total. Just like when you collect tamarind seeds after playing a game and count how many you got — that’s addition! Real-Life Example: Shopping at the Store Imagine you went to a shop and saw different items with price tags: Now you want to know how much money you’d need to buy both. We add the numbers like this: markdown  2454  (Cost of Mobile) +  324  (Cost of Calculator) ——-   2778  (Total) So, you’d need ₹2778 in total! Let’s Understand Addition Step-by-Step Let’s take one more example. A housewife buys: Let’s add their prices together. markdown  2420 + 1349 ——-   3769 That means she spent ₹3769 in total. Always remember: Start adding from the units place, then move to tens, then hundreds, and finally thousands. Addition with Carrying (Regrouping) Sometimes when you add, the total in one column becomes more than 9, so you need to carry the extra value to the next place. Let’s look at an example: Let’s add: markdown   3847 +  2454 ——-    6301 Here’s how we got that: 1️ Add units: 7 + 4 = 11 → write 1 and carry 12️Add tens: 4 + 5 = 9 → plus the carry = 10 → write 0 and carry 13️Add hundreds: 8 + 4 = 12 → plus 1 = 13 → write 3 and carry 14️ Add thousands: 3 + 2 = 5 → plus 1 = 6 So, total = ₹6301 Wasn’t that fun? Adding in Your Head (Mental Math) Sometimes, you don’t even need paper and pencil! You can add numbers in your mind by breaking them up. For example:328 + 241 Let’s split 241 into parts: 328 + 200 = 528   528 + 40 = 568   568 + 1 = 569 So, 328 + 241 = 569 Easy, right? Let’s try a bigger one: 5347 + 2635 Break 2635 into 2000 + 600 + 30 + 5 yaml 5347 + 2000 = 7347   7347 + 600 = 7947   7947 + 30 = 7977   7977 + 5 = 7982 FAQs  Q: Do I always need to carry when adding 4-digit numbers? A: No, only when the total in one place is 10 or more. Then we carry to the next place. Q: What should I do first while adding? A: Always start from the units place (the rightmost number). Q: Can I add numbers without writing them down? A: Yes! That’s called mental math. You can break numbers into parts and add them step by step in your mind. Q: Why do we need to learn addition? A: Because we use it every day — at shops, while cooking, or even counting your toys! Q: I made a mistake while adding. What should I do? A: That’s okay! Mistakes help you learn. Just check each step and try again. You’ll get it! Keep Exploring! Addition is a superpower you’ll use all your life — whether you’re counting pencils, chocolates, or helping at home. Practice a little every day and you’ll become an Addition Expert in no time!Remember children, if something feels tricky, don’t be shy to ask your teacher.

The Three Butterflies

Once upon a time, there were three beautiful butterflies: a pink one, a red one, and a yellow one. They loved playing in the sunshine, flying from one flower to another. They danced in the air, feeling the warm breeze and never growing tired. One day, the weather changed, and it started to rain. The butterflies got all wet. They needed a place to stay dry. So, the pink butterfly flew to a rose and said, “Good Rose, could you please open your petals so we can take shelter from the rain?” The rose kindly replied, “I’d love to shelter you, pink butterfly, because you look like me. But I can’t shelter your two friends.” The pink butterfly was sad. She said, “If you won’t shelter my friends, then I don’t want to shelter here either. I’ll stay wet rather than leave them.” Then, they flew to a sunflower. “Dear Sunflower, please open your petals and help us stay dry,” said the yellow butterfly.The sunflower smiled and said, “I’d be happy to shelter you, yellow butterfly, but not the others.” The yellow butterfly replied, “If you won’t shelter my friends, I’d rather stay wet with them.” The sun, who had been hiding behind the clouds, had heard everything. He was so happy to see the butterflies sticking together. So, he chased the rain away, and the clouds disappeared. The sun shone brightly and dried the butterflies’ wings. Now, the butterflies could play and dance from flower to flower, just like before. They were happy to be together again and enjoyed the rest of the day. FAQs Why didn’t the pink butterfly want to stay with the rose? The pink butterfly didn’t want to stay with the rose because the rose only wanted to shelter her and not her two friends. The pink butterfly cared about her friends and didn’t want to leave them. Why did the yellow butterfly stay with her friends? The yellow butterfly stayed with her friends because she didn’t want to leave them out in the rain, even though the sunflower offered her shelter. How did the butterflies feel at the end of the story? The butterflies were happy because the sun helped them, and they were able to play again, flying from flower to flower with their wings dry and ready to dance. What did the sun do when he saw the butterflies? The sun was happy to see the butterflies together. He chased away the rain and dried their wings so they could play and have fun again.

I WANT TO FLY

Hey kids! Have you ever wondered what it would be like to have wings and fly like a bird? Imagine being able to soar high up in the sky, seeing the world from above! Let’s dive into a fun poem that talks about just that. The poet in the poem dreams about having wings to fly. They say if they had wings, they would fly up into the sky, feeling the wind in their feathers. But that’s not all! They would also carry a paintbrush and lots of colors—bright and beautiful ones—so they could paint the clouds in the sky. Imagine clouds turning purple, yellow, and green! The poet wants to make the sky even more beautiful by painting rainbows every day. Wouldn’t that be fun? Every time you look up, you’d see a colorful rainbow! And when night comes and the moon and stars appear, the poet imagines painting them too. The sky would look magical, don’t you think? Now, let’s think about the “If I had” and “If I were” parts! These phrases help us dream and imagine what we could do if we had something special, like wings or other cool things.

Perimeter and Area of Simple Geometrical Figures

Hello, friends! Today, let’s learn about two very important concepts in geometry: Perimeter and Area. Don’t worry, we will keep it simple and fun! What is Perimeter? Let’s start with perimeter. Imagine Raju’s father bought a piece of land and wants to put a fence around it. How do we figure out how much wire is needed to surround the land? That’s right, we need to find the perimeter. So, what exactly is the perimeter? It’s just the total length around a figure. It’s like walking along the boundary of a shape and counting how many steps you take. Example: Let’s look at a simple quadrilateral. Here are its sides: To find the perimeter, we add up all the side lengths:Perimeter = AB + BC + CD + DA = 8 cm + 6 cm + 7 cm + 4 cm = 25 cm So, the total distance around the shape is 25 cm. That’s the perimeter! Why Do We Need Perimeter? We use perimeter to know how much border, wire, or fence we need. For example, when Rita wants to put a border around her table, she’ll calculate the perimeter to see how much border she’ll need. Quick Activity: Look around your classroom. Can you find different objects that have a perimeter? How about the top of your desk or the window? Try measuring their sides and adding them up to find the perimeter! What is Area? Now, let’s talk about area. The area tells us how much space is inside a shape. For example, think of a table, a blackboard, or a book. Which one covers more space? The blackboard has the biggest area, and the book has the smallest area. This is because the blackboard takes up more space on the surface, and the book takes up less. How to Find the Area? We find the area of a shape by multiplying its length and breadth. For example, if the length of a rectangle is 3 cm and its breadth is 3 cm, we calculate the area like this: Area = Length × Breadth = 3 cm × 3 cm = 9 cm² So, the area of this shape is 9 square centimeters (cm²). Units of Area Practical Use of Area Why do we need to know the area? Imagine a carpenter is building a table. He needs to know how much wood to use, so he calculates the area of the table’s top surface. Similarly, a tailor needs to know how much cloth to buy for stitching a shirt, so they calculate the area of the cloth. Quick Activity: Can you think of other places where we calculate area? Like the floor of a room or the space for a garden? Write down a few examples! FAQs 1. What is the difference between perimeter and area? 2. How do we find the perimeter of a triangle? Just add up all the sides! For example, if the sides of a triangle are 4 cm, 5 cm, and 6 cm, the perimeter would be:Perimeter = 4 cm + 5 cm + 6 cm = 15 cm. 3. How do we calculate area for different shapes? For rectangles and squares, multiply the length and breadth. For other shapes, we may need special formulas, but don’t worry! We’ll learn them soon. 4. Why do we need to measure area? We measure area to know how much space something takes up. This helps us in real life, like when buying materials for a project or deciding how big something can be!
