Full lesson	Create for a teacher a set of content for giving a lesson, beginning with the lesson plan. Each new block of materials must begin with an H1 heading (other subheaders must be H2, H3, etc). When you describe required pictures, write those descriptions in curly brackets, for example: {A picture of a triangle}

Lesson plan

Topic

Additional with Regrouping

Objectives

• Students will understand the concept of addition with regrouping.
• Students will be able to accurately perform addition problems that require regrouping.
• Students will develop their problem-solving and critical-thinking skills through practice.

Materials

• Whiteboard and markers
• Addition worksheets (with regrouping exercises)
• Manipulatives (like base-10 blocks or counters)
• Timers for activities
• Individual dry erase boards and markers for each student

Grade/Age Group

• Grade 2-3 (Ages 7-9)

Subject

• Mathematics

Class Size

• 20 students

National Curriculum Alignment

• This lesson corresponds to the Common Core Standards for Mathematics:
  • 2.NBT.B.7: Add and subtract within 1000, using strategies and algorithms based on place value, properties of operations, and/or the relationship between addition and subtraction.

Lesson Structure

Step Number	Step Title	Length	Details
1	Introduction to Regrouping	5 min	Introduce the concept of regrouping using a simple example on the whiteboard. Discuss why we need to regroup when the digits in a place value exceed 9.
2	Guided Practice	10 min	Work through 3 addition problems as a class, using manipulatives to visualize regrouping. Encourage students to share their thought processes.
3	Independent Practice	10 min	Distribute addition worksheets. Allow students to work independently on problems requiring regrouping while providing support as needed.
4	Quick Check	3 min	Review answers together as a class without students presenting their work. Discuss common mistakes and clarify any concepts.
5	Closing and Homework Assignment	2 min	Summarize the lesson. Assign additional addition problems for homework that focus on regrouping. Encourage students to practice a few problems each day.

Homework

• Complete a worksheet with 10 addition problems that involve regrouping.
• Encourage students to show their work and review their answers with an adult at home.

Assessment

• Informal assessment through observation during guided and independent practice.
• Check homework for understanding and accuracy, providing feedback in the following lesson.

Additional Notes

• Be prepared to differentiate instruction for students who may struggle with the concept.
• Consider pairing students for peer support during independent practice.
