Lesson Plan for Rounding Whole Numbers

Subject

Mathematics

Topic

Rounding Whole Numbers

Grade/Age Group

Grade 3

Length of Lesson

30 minutes

Number of Students

20

National Curriculum Alignment

This lesson plan is aligned with the Common Core State Standards for Mathematics, specifically focusing on 3.NBT.A.1 (using strategies to round whole numbers to the nearest 10 or 100).

Objectives

• Students will understand the concept of rounding whole numbers.
• Students will be able to round numbers to the nearest 10 or 100.
• Students will apply their rounding skills in problem-solving situations.

Materials

• Whiteboard and markers
• Rounding number charts
• Worksheets with rounding exercises
• Pencils
• Rounding games (printable or digital)

Assessment

• Informal assessment through observation during the lesson.
• Collection of rounding worksheets for feedback and grading.

Homework

• Complete a rounding worksheet with practice problems.
• The homework will be checked by the teacher without requiring students to present it in front of the class.

Lesson Structure

Step Number	Step Title	Length (minutes)	Details
1	Introduction to Rounding	5	Discuss what rounding is and why we use it. Provide examples of rounding numbers in everyday life.
2	Demonstration	10	Show how to round a number using the rounding rule (if it's 5 or higher, up; if it's 4 or lower, down). Use visual aids and examples.
3	Guided Practice	5	Work together on a few rounding problems as a class. Ask students to volunteer answers and clarify misconceptions in real-time.
4	Independent Practice	7	Distribute worksheets for students to practice rounding on their own. Circulate around the classroom to provide individual support.
5	Review and Wrap-Up	3	Quickly review the answers to the worksheets without putting students on the spot. Invite any final questions and summarize the key points of the lesson.

Additional Notes

• Be sure to modify group work based on the varying skill levels of students.
• Encourage a supportive class environment that fosters participation and reduces anxiety related to answering questions aloud.
