Topic: Comparing Size and Mass
Introduction
This week, we will explore the concepts of size and mass. Children will learn to compare objects and use language like 'bigger', 'smaller', 'heavier', and 'lighter'.
Tasks
Practice comparing everyday objects. Use a balance scale to compare the mass of different items.
📊 Comparing Size and Mass
Size is how big or small something is. Mass is how heavy it is. We can use words like big, small, long, short, tall, heavy, and light.
🔹 Comparing Size
Look at two objects and decide which is bigger or smaller.
Examples:
- A bus is bigger than a car.
- An apple is smaller than a watermelon.
🔹 Comparing Mass
Hold two objects to feel which is heavier or lighter. You can use a balance scale to check.
Examples:
- A book is heavier than a pencil.
- A feather is lighter than a stone.
📝 Practice Exercises
- Find something bigger than your hand.
- Find something smaller than your shoe.
- Which is heavier, a toy car or a teddy bear?
- Which is lighter, a leaf or a rock?
- Order three different-sized balls from smallest to largest.
You can compare the size of anything!
Heavier things are not always bigger.
Use your hands as a balance scale to feel the difference.
