# Comparing Containers: Which One Holds More or Less? - Size Lesson Plan

• Do you want to help your students develop their spatial reasoning and measurement skills? Do you want to make learning about the vocabulary “holds more” or “holds less” fun and engaging? If so, this lesson plan is for you! In this lesson, your students will learn how to compare the sizes and capacities of different containers, such as glasses, buckets, cups, and bowls.

They will learn how to use words like "more" and "less" to describe how much liquid or solid each container can hold. They will also watch some videos to reinforce their understanding of the concept and challenge them to apply their knowledge.

## Advantages of following this lesson plan for kids

• This lesson plan is designed to meet the needs of pre-kindergarten, kindergarten, and 1st Grade students to teach them about size. It is based on research that shows that spatial reasoning and measurement skills are essential for children's cognitive development and academic achievement. By following this lesson plan, you will help your students:

• Develop their vocabulary and language skills related to size and capacity
• Enhance their visual perception and attention skills
• Improve their logical thinking and problem-solving skills
• Foster their curiosity and creativity
• Have fun and enjoy learning

Duration: 20 - 30 minutes

Objectives: By the end of this lesson, students will be able to:

• Identify different containers and objects by their names
• Compare the sizes and capacities of different containers using words like "more" and "less."
• Estimate how much liquid or solid each container can hold
• Measure the amount of liquid or solid in each container using non-standard units, such as spoons or cups
• Watch videos that illustrate the concept of size and capacity and answer questions related to them

This lesson plan is flexible and adaptable to different classroom settings and situations. You can adjust the duration, difficulty, and number of activities according to your students' needs and interests. You can also use different materials and resources that are available to you.

• ### Previous knowledge

Before attending this lesson, your students should know:

• The names of some standard containers and objects, such as glass, bucket, cup, bowl, water, sand, etc.
• The names of some basic shapes, such as circles, squares, triangles, etc.
• How to count up to 10
• How to follow simple instructions

### Materials

For this lesson, you will need:

• A computer or a projector with internet access to play the videos
• A large chart paper or a whiteboard with markers
• Several containers of different sizes and shapes include glasses, buckets, cups, bowls, etc.
• Some liquid or solid materials that can fill the containers, such as water, sand, rice, beans, etc.
• Some non-standard units for measuring the amount of liquid or solid in each container, such as spoons, cups, etc.
• Some stickers or stamps to reward the students

• ### Introduce the lesson

To introduce the lesson, you can:

• Show the students some containers of different sizes and shapes and ask them to name them
• Ask the students if they know what capacity means and explain that it is how much something can hold
• Ask the students if they can guess which container can hold more or less liquid or solid than another one
• Write the words "more" and "less" on the chart paper or the whiteboard and explain that they are used to compare the capacities of different containers.
• Tell the students that they are going to watch some videos that will help them learn more about size and capacity.
• ### Warm-up

To warm up the students, you can:

• Play the first video from this link: https://youtu.be/Qz9HfwlM4zM
• Pause the video after each question and ask the students to answer it by raising their hands or shouting out loud
• Praise the students for their answers and correct them if needed
• Repeat the process with the second video from the same link
• ### Introducing the concept

To introduce the concept of size and capacity, you can:

• Show the students two containers of different sizes and shapes, such as a glass and a bucket
• Ask the students which one can hold more liquid or solid than the other one
• Demonstrate how to fill each container with water or sand using a spoon or a cup
• Count how many spoons or cups it takes to fill each container
• Write down the numbers on the chart paper or the whiteboard next to each container
• Ask the students to compare the numbers and tell which container holds more or less than the other one
• Explain that sometimes we can tell which container holds more or less by looking at their sizes and shapes, but sometimes we need to measure those using spoons or cups.
• Repeat the process with other pairs of containers of different sizes and shapes.
• ### Activities and games

To reinforce the concept of size and capacity, you can:

• Divide the students into small groups and give each group some containers of different sizes and shapes, some liquid or solid materials, and some non-standard units for measuring
• Ask each group to fill the containers with liquid or solid materials and measure how much they can hold using the non-standard units.
• Ask each group to write down the numbers on paper or a sticky note.
• Ask each group to compare their numbers with the other groups and tell which container holds more or less than the other one.
• Play the third video from this link: https://youtu.be/Qz9HfwlM4z
• Pause the video after each question and ask the students to answer it by using their containers and materials
• Praise the students for their answers and correct them if needed
• ### Group Sharing

To encourage group sharing, you can:

• Ask each group to present their containers, materials, and numbers to the whole class
• Ask the other groups to comment on their findings and ask questions
• Summarize the main points of the lesson and review the vocabulary and the concepts
• ### Conclusion

To conclude the lesson, you can:

• Play the fourth video from this link: https://youtu.be/Qz9HfwlM4zM
• Pause the video after each question and ask the students to answer it by using their containers and materials
• Praise the students for their answers and correct them if needed
• Give each student a sticker or a stamp for their participation and effort
• Tell the students that they did a great job and that they learned a lot about size and capacity

### ✨ Assessment

To assess the students' learning, you can:

• Give each student a worksheet with some pictures of different containers and objects
• Ask them to circle the container that holds more or less than the other one in each pair
• Collect the worksheets and check their answers
