Story Time: Sahil's Shadow Adventure

Hey kids, today let's go on a fun journey with Sahil into the world of shadows.

• Sahil was a curious boy. 
• One evening, when his mom lit a candle, Sahil saw something cool.
  
• When he walked past the candle, he saw shapes on the walls. 
• He asked his mom, "What are these shapes?"

• Mom said, "Those are shadows, Sahil. They come when something blocks the light."
• Excited, Sahil tried making shapes with his hands in front of the candle. He made a bird, a heart, and a funny face. Each time, a shadow showed up on the wall.
  
• Then Sahil took his ball and put it between the candle and the wall. The ball made a circle shadow. Sahil said, "Look, a circle shadow from the ball!"

• Next, he got his birthday cap and put it near the candle. The cap's shadow looked like a tall cone. Sahil laughed, "My cap's shadow is like a Triangle!"

• Sahil also tried his geometry box. Its shadow was a rectangle. He said, "The box makes a straight shadow, just like its shape!"

Rectangle Shadow made by Geometry boxSahil had so much fun exploring shadows with different things. He learned that each thing makes a special shadow based on its shape. And that's how Sahil's shadow adventure taught him about different shapes as well.

From Sahil's adventure, we have explored the amazing world of shapes. Let's Learn more!

Shapes

Shapes are like the building blocks of everything around us. They can be round like a ball, have four sides like a square, three sides like a triangle, or even more sides like a rectangle. They help us understand and describe the world in a fun and interesting way!

There are different types of shapes, Let's learn about them.

Different Shapes

1. Square: A square has four equal sides. Imagine a perfect square cookie with all sides the same length. It's like a perfect box or a checkerboard tile.
Square

2. Rectangle: Similar to a square, a rectangle has four sides, but its opposite sides are equal in length. Imagine a door or a window—it's taller or wider than a square, but it still has those right angles.
Rectangle

3. Triangle: Imagine a triangle like a slice of pizza or a big pointy hat. It has three sides and three corners. You can find triangles in Pizza slice, birthday cap , just like sahil. Triangle

4. Circle: Think of a circle as a perfectly round ball. It doesn't have any corners or edges. When you draw a circle, it goes around and around, just like the wheels on a bicycle!

Circle5. Oval: An oval is like a stretched-out circle. It's not perfectly round but still smooth and curved, like an egg or a rugby ball.

Now that we know about shapes, Let's help Aanya to colour the rangoli.

Learn by Practicing- Aanya's Rangoli

• Once upon a time, there was a girl named Aanya who loved coloring and creating beautiful artwork. 
• One day, she opened her coloring book to a page with a lovely rangoli design.

• The design was filled with different shapes like circles, squares, and triangles, each waiting to be colored .
• Let's see how Aanya coloured the rangoli.

Step 1: Aanya looked at the rangoli design and decided to start with the circles.

Step 2: Checking the instructions in her coloring book, Aanya found that circles were supposed to be blue.

Step 3: With her blue crayon in hand, Aanya carefully identified the circle in the rangoli pattern and colored it beautifully in blue.

Step 4: Moving on to the squares, Aanya checked the instructions again. Squares were meant to be green.

Step 5: Aanya smiled and started coloring the squares with her bright green crayon, filling each square with cheerful green color.

Step 6: Lastly, Aanya looked for the triangles in the rangoli. According to the instructions, triangles were to be yellow.

Step 7: Taking her yellow crayon, Aanya added a touch of yellow to each triangle, completing the colorful and vibrant rangoli design.

As Aanya stepped back to admire her work, she felt a sense of pride and happiness. The rangoli looked stunning with its blue circles, yellow squares, and green triangles, creating a harmonious and delightful artwork.

With Aanya's colouring activity we got to practice shapes. Let's move on and learn about Patterns.

Patterns

Patterns are like beautiful designs that repeat in a special way. 

• Imagine you have a line of colorful blocks: red, blue, green, red, blue, green, and so on.
  
• This is a pattern because it keeps repeating in the same order: red, blue, green, red, blue, green.
• Patterns can be made of shapes, colors, or even with numbers.
• They can be found in nature, like the stripes on a zebra or the petals on a flower.
  

Learning about patterns helps us understand how things repeat in a predictable way, which is super fun and interesting!

Now that we know what patterns are, Let's go on an adventure with Kunal.

Learn by Practicing- Kunal's fruity pattern

• Once upon a time, there was a boy named Kunal who loved organizing things. 
• One sunny day, he decided to arrange his favorite fruits on the kitchen table. He had some juicy mangoes, shiny apples, and sweet pears.
  
• Instead of putting them all in one group, Kunal wanted to create something special. 
• He thought for a moment and then arranged them in a pattern. First, he placed an apple, then a mango, and after that, a pear.
  
• But when he tried to continue the pattern, he got a bit confused. Kunal wanted the arrangement to look beautiful and repeat in a special way, but he wasn't sure how to do it.
• Just then, his older brother Raj walked into the kitchen. Raj was good at solving puzzles and figuring out patterns. Kunal asked for his help, "Raj bhaiya, can you help me make a pattern with these fruits?"
  
• Raj smiled and said, "Of course, Kunal! Let's see what you've done so far." He looked at the fruits on the table and noticed the arrangement: apple, mango, pear.
• Raj said, "You've already started a pattern! You just need to repeat what you've created." He picked up another apple and placed it next to the pear. "Look, now it's apple, mango, pear, apple. That's a pattern!"
  
• Kunal's eyes lit up with excitement. He understood now. With Raj's guidance, they continued the pattern: apple, mango, pear, apple, mango, pear, and so on.
  

By creating this fruity pattern, Kunal learned how repeating a sequence can make things look organized and interesting. 

Number Patterns

Patterns can be anywhere, even in numbers. 

• Imagine you can block of different numbers from 1 to 6 arranged in a line.
  
• If you keep 1 and remove 2, then keep 3 and remove 4 and continue the pattern,  keep 5 and remove 6, then you will end up with a pattern of numbers where 1 number is being skipped. 
  
• There are many ways to form number patterns.

Keep looking for different patterns around you and see how you can continue them.
