Rolling and Sliding | Maths for UKG PDF Download

Hello, my young friends! Today, we're going to learn about something really cool - "Rolling and Sliding." We'll explore how objects move in different ways, and I'll show you lots of examples and pictures to help you understand.

Rolling

• Rolling is when an object moves by turning or rotating around its center.
• Imagine a car's wheel rolling on the road. The wheel goes round and round.
• A ball, like a soccer ball or a basketball, also rolls when you push it.

Examples of Rolling

• A bicycle wheel
• A rolling pin used in the kitchen
• A roundabout at the playground

Sliding

• Sliding is when an object moves on a surface without turning or rotating.
• Think of a sled sliding down a snowy hill. It glides on the snow.
• When you push a book across a table, it slides.

Examples of Sliding

• Ice sliding on a skating rink
• A penguin sliding on its belly on the ice
• Sliding down a slide at the park

Now, let's compare rolling and sliding

• Rolling objects usually have a round shape, like wheels and balls.
• Sliding objects can be flat or have different shapes, like sleds and books.
• Rolling objects turn or rotate as they move.
• Sliding objects move in a straight line on a surface.

Let's play a game

• Can you tell me if these objects are rolling or sliding?
• A car on the road
  
• A skateboard on the pavement
  
• A kite flying in the sky
  

Summary

• Today, we learned that objects can move in two ways - rolling and sliding.
• Rolling objects go round and round, like wheels and balls.
• Sliding objects move in a straight line on a surface, like sleds and books.

So, keep your eyes open, and you'll see rolling and sliding all around you. Remember, learning is fun, and the world is full of exciting things to discover!
