Measuring in Litres and Millilitres

Learning Objective

At the end of the lesson you should be able to measure liquids in litres and millilitres, and convert between the two without decimals.

Introduce the learning objective of the lesson and explain what students will be able to do by the end of the lesson.

What do you already know about measuring liquids?

What is a Litre?

A litre is a unit of measurement for liquids. It is equal to 1000 millilitres (ml).

Define what a litre is and explain how it relates to millilitres. Provide examples of common items that are measured in litres.

What is a Millilitre?

A millilitre is a smaller unit of measurement for liquids. It is equal to 1/1000th of a litre.

Define what a millilitre is and explain how it relates to litres. Provide examples of common items that are measured in millilitres.

Measuring in Litres

To measure in litres, use a measuring jug and look at the markings on the side. Each marking represents a certain amount of litres.

Demonstrate how to measure in litres using a measuring jug. Show students how to read the markings on the side of the jug.

Measuring in Millilitres

To measure in millilitres, use a measuring cylinder and look at the markings on the side. Each marking represents a certain amount of millilitres.

Demonstrate how to measure in millilitres using a measuring cylinder. Show students how to read the markings on the side of the cylinder.

Converting Between Litres and Millilitres

To convert from litres to millilitres, multiply the number of litres by 1000. To convert from millilitres to litres, divide the number of millilitres by 1000.

Explain the process for converting between litres and millilitres. Provide examples and allow students to practice the conversions.

Practice: Converting Litres to Millilitres

Convert 3 litres to millilitres.

Ask students to convert 3 litres to millilitres. Provide the answer and explain how to arrive at the answer.

Practice: Converting Millilitres to Litres

Convert 5000 millilitres to litres.

Ask students to convert 5000 millilitres to litres. Provide the answer and explain how to arrive at the answer.

Measuring in Practice: Water Bottle

This water bottle has a capacity of 500ml.

Show an image of a water bottle with the capacity labelled in millilitres. Ask students to identify how much liquid the bottle can hold.

Measuring in Practice: Milk Carton

This milk carton has a capacity of 2 litres.

Show an image of a milk carton with the capacity labelled in litres. Ask students to identify how much liquid the carton can hold.

Quiz: Litres and Millilitres

What is the difference between a litre and a millilitre?

Create a quiz question to test students' understanding of the difference between litres and millilitres.

Quiz: Conversions

Convert 2500 millilitres to litres.

Create a quiz question to test students' ability to convert between litres and millilitres.

Summary

In this lesson, you learned how to measure liquids in litres and millilitres, and how to convert between the two without decimals.

Summarize the key points of the lesson and remind students of what they learned.

Further Practice

Practice measuring liquids in litres and millilitres using different containers and volumes.

Encourage students to practice measuring liquids using various containers and volumes to reinforce their understanding.

Further Learning

Explore how liquids are measured in other parts of the world, and how different cultures use different measuring systems.

Encourage students to research how liquids are measured in other parts of the world and how different cultures use different measuring systems.

Write down 3 things you learned in this lesson.

Have students enter three things they learned in this lesson. With this they can indicate their own learning efficiency of this lesson.

Write down 2 things you want to know more about.

Here, students enter two things they would like to know more about. This not only increases involvement, but also gives them more ownership.

Ask 1 question about something you haven't quite understood yet.

The students indicate here (in question form) with which part of the material they still have difficulty. For the teacher, this not only provides insight into the extent to which the students understand/master the material, but also a good starting point for the next lesson.
