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: Adding Expressions

Subject:

Mathematics

Topic:

Adding Expressions

Grade/Age Group:

Grade 7

Length of Lesson:

30 minutes

Number of Students:

20

Objectives:

• Students will be able to identify like terms in algebraic expressions.
• Students will demonstrate the ability to add expressions with like terms correctly.
• Students will apply the properties of addition to simplify algebraic expressions.

Materials:

• Whiteboard and markers
• Handouts with practice problems
• Algebra tiles (optional)
• Interactive math software or online resources (optional)

National Curriculum Alignment:

This lesson aligns with the Common Core State Standards for Mathematics, specifically focusing on the standard that addresses the use of operations to solve problems involving algebraic expressions.

Lesson Structure:

Step Number	Step Title	Length (minutes)	Details
1	Introduction	5	Introduce the topic of adding expressions and its importance in mathematics. Use real-life examples to illustrate.
2	Review Like Terms	5	Review the concept of like terms with examples on the board. Engage students with questions about identifying like terms in given expressions.
3	Guided Practice	10	Provide students with sample problems on the board. As a class, solve the first few problems together, highlighting strategies for adding expressions.
4	Independent Practice	5	Distribute handouts with practice problems. Allow students to work independently while circulating to offer support as needed.
5	Homework Assignment	4	Assign additional practice problems on adding expressions as homework. Explain that homework will be collected and checked for completion but not presented in class.
6	Closing & Review	1	Summarize the key concepts learned during the lesson. Encourage students to ask any remaining questions.

Homework:

• Complete the assigned practice problems on adding expressions. Ensure understanding of how to identify like terms and simplify the expressions.

Assessment:

• Informal assessment will take place during the guided and independent practice through observation and support.
• Homework will be checked for completion only, without requiring student presentations.

Additional Notes:

• Encourage students to ask for help if they are struggling with any concepts during practice.
• Utilize technology or interactive resources to enhance understanding if available and applicable.
