Grade: 3rd

Subject: Mathematics and Science

Topic: Subtracting 3 to 4-digit numbers from 3 to 4-digit numbers with regrouping and Science Integration

Objective: - Students will be able to subtract 3 to 4-digit numbers from 3 to 4-digit numbers with regrouping. - Students will be able to apply their subtraction skills to solve real-life science problems.

Materials: - Whiteboard or blackboard - Markers or chalk - Subtraction worksheets - Science-related word problems - Science-related objects or pictures (optional)

Procedure:

Introduction (10 minutes): 1. Begin the lesson by asking students if they know what subtraction is and when it is used in real life. 2. Write a simple subtraction problem on the board, such as 456 - 238, and solve it together as a class. 3. Explain that today, they will be learning how to subtract larger numbers with regrouping and apply their skills to solve science-related problems.

Subtraction with Regrouping (20 minutes): 1. Review the concept of regrouping in subtraction. Remind students that when subtracting, if the digit in the bottom number is larger than the digit above it, they need to borrow from the next place value. 2. Model a few examples of subtracting 3 to 4-digit numbers from 3 to 4-digit numbers with regrouping on the board. Make sure to explain each step clearly. 3. Provide guided practice by solving a few subtraction problems together as a class. Gradually increase the difficulty level of the problems. 4. Distribute subtraction worksheets to students and allow them to practice independently. Circulate the classroom to provide assistance and feedback as needed.

Science Integration (15 minutes): 1. Introduce the science integration component by explaining that they will now apply their subtraction skills to solve science-related word problems. 2. Provide a few examples of science-related word problems on the board, such as: - “There were 876 insects in a garden. 342 flew away. How many insects are left?” - “A scientist had 1,245 milliliters of water in a beaker. She poured out 678 milliliters. How much water is left in the beaker?” 3. Solve the first word problem together as a class, emphasizing the importance of understanding the context and identifying the relevant numbers. 4. Allow students to work in pairs or small groups to solve the remaining science-related word problems. Encourage them to discuss their strategies and explain their thinking to each other.

Conclusion (5 minutes): 1. Gather the class together and review the key concepts covered in the lesson: subtracting 3 to 4-digit numbers with regrouping and applying subtraction skills to solve science-related problems. 2. Ask a few students to share their solutions to the science-related word problems and discuss their strategies as a class. 3. Provide positive feedback and reinforce the importance of practicing subtraction skills regularly. 4. Assign additional practice problems or homework if necessary.

Note: The duration of each section can be adjusted based on the pace and needs of the students.
