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}

• Homework handout

Grade/Age Group

2nd to 4th Grade

Subject

Mathematics

Class Size

20 Students

National Curriculum

This lesson aligns with the Common Core State Standards for Mathematics, specifically:

• Operations and Algebraic Thinking (2.NBT.B.5): Add and subtract within 100.

Lesson Structure

Step Number	Step Title	Length	Details
1	Introduction	5 Minutes	Introduce the topic of adding double digits. Explain the objectives for the lesson.
2	Direct Instruction	10 Minutes	Demonstrate how to add double-digit numbers using examples on the whiteboard. Include carrying over techniques.
3	Guided Practice	5 Minutes	Lead the class through a few practice problems, asking for volunteers to solve them on the board. Check for understanding.
4	Independent Practice	5 Minutes	Distribute worksheets with double-digit addition problems. Allow students time to complete them on their own.
5	Group Activity	3 Minutes	Split students into pairs or groups to solve a set of additional problems together, encouraging collaboration.
6	Review and Discuss	2 Minutes	Briefly go over the answers to the worksheet as a class, addressing any mistakes or misunderstandings.
7	Homework Explanation	2 Minutes	Assign homework that reinforces the lesson, providing a separate handout with problems to complete at home.

Assessment

• Monitor student understanding and participation during guided and independent practice.
• Check homework for accuracy without requiring presentations in front of the class, using a quick review of the answers in the next lesson.

Homework

• Assign double-digit addition problems (10 problems) for practice at home, with instructions for students to bring completed work to the next class for review.
