Lesson Content

Day 1: Number Work (560-570)

New Number Range:

• Count from 560-570: 560, 561, 562… 570
• Order numbers from 1-570
• Write clearly: 565 = five hundred and sixty-five
• Skip counting practice in 2s, 3s, and 10s

Day 2: Understanding Capacity

What is Capacity? Capacity is how much a container can hold. It tells us the amount of liquid, solid, or other substances that can fit inside a container.

Examples of Capacity:

• How much water a cup can hold
• How many marbles fit in a jar
• How much rice a pot can contain
• How many books fit in a bag

Why is Capacity Important?

• Helps us choose the right container size
• Important for cooking (measuring ingredients)
• Helps in storage and organization
• Important for buying containers and planning

Day 3: Objects Used for Measuring Capacity

Measuring Tools for Capacity:

1. Cup: For measuring liquids like water, milk
2. Spoon: For small amounts of liquids or solids
3. Bucket: For larger amounts of water
4. Jerry can: For storing and carrying liquids
5. Bottle: Various sizes for different amounts
6. Bowl: For holding food or liquids
7. Jug: For pouring and measuring liquids

Container Examples:

• Small containers: Spoons, small cups, medicine bottles
• Medium containers: Regular cups, bowls, small buckets
• Large containers: Big buckets, jerry cans, cooking pots

Day 4: Arranging Containers by Capacity

Ordering by Capacity:

• Smallest to largest: Start with containers that hold the least
• Largest to smallest: Start with containers that hold the most

Example Ordering (smallest to largest):

1. Spoon (smallest capacity)
2. Small cup
3. Large cup
4. Bowl
5. Bucket (largest capacity)

Comparing Capacities:

• Holds more: Container with larger capacity
• Holds less: Container with smaller capacity
• Holds the same: Containers with equal capacity

Day 5: Practical Capacity Activities

Filling Containers:

• Count how many small cups of water fill a bucket
• Count how many spoons of rice fill a cup
• Count how many marbles fit in different containers

Real-Life Applications:

• Cooking: measuring ingredients
• Storage: organizing household items
• Shopping: choosing container sizes
• Water storage: planning for family needs

Problem-Solving: Apply capacity knowledge to daily situations

Examples in Class

Capacity Comparison Examples:

Using Classroom Containers:

• “This bucket holds more water than this cup”
• “The big jar holds more marbles than the small jar”
• “Two identical cups hold the same amount”

Kitchen Examples:

• “A cooking pot holds more soup than a bowl”
• “A tablespoon holds less than a cup”
• “A jerry can holds more water than a bottle”

Real-Life Examples:

At Home:

• “Mom’s big cooking pot holds more rice than the small pot”
• “The water storage tank holds more than all our buckets combined”
• “A medicine spoon holds very little compared to a drinking cup”

In the Market:

• “The large container of oil costs more because it holds more”
• “Small sachet water holds less than a bottle of water”

Exercises

Exercise 1: Number Work

Write in words:

1. 562 = _______________
2. 567 = _______________
3. 570 = _______________

Order from smallest to largest: 4. 568, 563, 570, 565, 561

Exercise 2: Understanding Capacity

1. What is capacity? _______________
2. Name 3 containers with small capacity: _____, _____, _____
3. Name 3 containers with large capacity: _____, _____, _____

Exercise 3: Measuring Objects

Match the container to its best use:

1. Spoon = _____ (a. Storing water for bathing, b. Taking medicine, c. Carrying fuel)
2. Jerry can = _____ (a. Drinking tea, b. Storing large amounts of liquid, c. Taking soup)
3. Cup = _____ (a. Storing rice for family, b. Drinking water, c. Bathing)
4. Bucket = _____ (a. Taking medicine, b. Drinking juice, c. Fetching water)

Exercise 4: Capacity Comparisons

Fill in “holds more,” “holds less,” or “holds the same”:

1. A bucket _______ than a cup
2. A spoon _______ than a bowl
3. Two identical bottles _______ amount
4. A jerry can _______ than a small bottle

Exercise 5: Ordering Containers

Arrange these containers from smallest to largest capacity:

1. Bucket, spoon, cup, bowl _____, _____, _____, _____ 
2. Jerry can, medicine bottle, drinking glass, cooking pot _____, _____, _____, _____ 

Exercise 6: Counting and Capacity

1. If 5 cups of water fill 1 bucket, how many cups will fill 2 buckets? _____ 
2. A small jar holds 20 marbles. How many marbles will 3 similar jars hold? _____ 
3. One spoon holds 5ml of medicine. How much will 4 spoons hold? _____ 

Exercise 7: Real-Life Capacity Problems

1. Mom needs to store water for the family. Should she use cups or buckets? Why? 
2. Dad wants to measure cooking oil. Which is better: a spoon or a cup? Why? 
3. Mary wants to carry water from the well. Which container should she choose: a bottle or a jerry can? Why? 
4. For taking liquid medicine, which is most suitable: a bucket, a cup, or a spoon? Why? 

Exercise 8: True or False

1. A bigger container always holds more than a smaller one (True/False)
2. All cups have the same capacity (True/False)
3. A jerry can holds more than a spoon (True/False)
4. Capacity helps us choose the right container size (True/False)

Exercise 9: Capacity Detective

Circle the container that holds MORE:

1. (Teaspoon / Bucket)
2. (Small cup / Large cup)
3. (Medicine bottle / Jerry can)
4. (Bowl / Spoon)
5. (Cooking pot / Plate)

Teaching Resources/Aids

• Various containers: cups, spoons, buckets, bottles, jerry cans
• Counting materials: marbles, beans, rice, water
• Measuring containers of different sizes
• Pictures of different containers with labels
• Chart showing capacity order from smallest to largest

• Ask for help with heavy containers
• Be gentle with breakable containers

Problem-Solving Strategies

Teaching Tips:

• Use actual containers for hands-on learning
• Start with familiar containers from students’ homes
• Connect to daily activities like cooking and storing

Assessment Questions

1. “Which container would you use to fetch water from a well?”
2. “How can you tell which container has more capacity?”
3. “Name three things you could measure with a cup.”
4. “Why is it important to understand capacity?”
5. “If one cup fills a bottle, how many cups will fill two bottles?”
