Lesson Structure

Step Number	Step Title	Length	Details
1	Introduction to Rounding	5 mins	Introduce the concept of rounding; explain why it is useful in mathematics and real life. Discuss the terms "round up" and "round down."
2	Explanation of Rounding Rules	10 mins	Teach the rules for rounding decimal numbers: identifying the decimal place to look at, and applying the rounding rules. Use examples on the whiteboard.
3	Guided Practice	5 mins	Work through several rounding problems as a class. Involve students in discussing their thought processes and solutions. Use the projector for visibility.
4	Independent Practice	5 mins	Distribute the practice worksheet with rounding problems for students to complete individually. Monitor progress and provide support as needed.
5	Review and Homework	5 mins	Go over the answers to the practice worksheet together as a class, ensuring understanding. Distribute a rounding decimals homework worksheet to reinforce learning.

Homework

• Distribute a rounding decimals worksheet for independent practice at home.
• Review homework in the next class without requiring student presentations—provide individual feedback instead.

Assessment

• Observe student participation during guided practice.
• Review completed independent practice worksheets for understanding.
• Check homework for accuracy and understanding in a subsequent lesson.
