• ### Introduce the lesson

To introduce the lesson, you can do the following:

• Ask your kids if they know what weight is and how they can measure it
• Explain that weight is how heavy or light something is and that they can use a scale or a balance to measure it
• Show them some examples of objects that are heavier or lighter than others, such as a feather and a rock or a pencil and a book
• Ask them to guess which object is heavier or lighter and why
• Tell them that they are going to watch a video that will teach them more about size and weight by comparing different objects and animals
• ### Warm-up

To warm up your kids for the video, you can do the following:

• Please show them some pictures of animals that vary in weight, such as elephants, mice, whales, etc.
• Ask them to name the animals and say which ones are heavier or lighter than others
• Give them some cards with the words heavier and lighter written on them
• Ask them to hold up the card that matches their answer
• Praise them for their answers and give them some stickers or stamps
• ### Introducing the concept

After the warm-up, do the following:

• Tell the students they will watch a video about size and measurement.
• Explain that size is how big or small something is, and measurement is how we compare different things.
• Tell them they will learn to use words like heavier and lighter to describe and compare objects and animals.

• Show them the video link (https://youtu.be/NXpQfHlMVNU) and ask them to pay attention to the narrator's questions and answers.
• Pause the video at specific points to check their understanding and ask them to repeat the words heavier and lighter. You can also ask them to point to the objects or animals that are heavier or lighter on the screen.
• ### Activities and games

After watching the video, you can do some activities and games with the students to reinforce their learning. Here are some ideas:

• Have a set of objects of different weights, such as books, pencils, balls, toys, etc. Ask the students to pick and compare two objects by holding them in their hands. Ask them to say which one is heavier and which one is lighter. You can also have a scale or a balance to show them how to measure the weight of the objects.
• Have some pictures of different animals, such as elephants, mice, whales, birds, etc. Ask the students to sort them from heaviest to lightest. You can also have them work in pairs or groups and give them a set of cards with the names of the animals. Ask them to match the cards with the pictures and say which animal is heavier or lighter than another.
• Play a guessing game with the students. Show them an object or an animal and ask them to guess if it is heavier or lighter than another object or animal. For example, you can show them a book and ask if it is heavier or lighter than a pencil. You can also use your body weight as a reference point. For example, ask them if they are heavier or lighter than you.
• ### Group Sharing

After doing some activities and games, have the students share what they learned with each other.

You can divide them into small groups and ask them to talk about what they liked or disliked about the video, what they found easy or challenging about the activities and games, and what they remember about size and measurement. You can also ask them to show each other some objects or animals they think are heavier or lighter than others.

• ### Conclusion

To conclude the lesson, review the main points with the students. Remind them that size is how big or small something is, and measurement is how we compare different things. Review the words heavier and lighter and ask them to give some examples of objects or animals that are heavier or lighter than others. Please praise them for their participation and effort.

### ✨ Assessment

To assess the students' learning, you can use different methods, such as:
