### Material / Resources

Writing board, chalk/marker, duster, pointer/stick, two empty bottles of one liter, a tub, textbook

### Introduction

• How do we measure the capacity of a container? • Which units are used to measure the quantity of milk? • Which is smaller unit of measuring capacity? • Which is the larger unit of measuring capacity? ### Development

Activity 1

• Describe a situation: A man who buys two milk packs one 250 ml and the other 500 ml. how much milk did he buys? Note: point out to the students we have added ml into ml.

• Only same quantity can be added together, e.g.: ml and ml or l and l. Activity 2

• Ask students to pour the water present in the two l empty bottles into an empty tub and tell what is the volume of the water in the tub? Activity 3 ### Sum up / Conclusion

• Inform to students that we have learnt today how to add quantities in liter and milliliter.
• Same units of measurement can be added;
• Liter can be added into liter.
• Milliliter can be added into milliliter.
