Duration: 45 minutes

Class Size: 45 students

Curriculum Area: Level 3 - Number and Algebra

Date: [Insert Date]

Learning Objectives:

• To understand and use basic algebraic expressions.

New Zealand Curriculum Links:

• Number and algebra: This lesson plan aligns with Level 3 of the New Zealand Curriculum, focusing on developing algebraic thinking by finding rules and expressing relationships using tables, words, and symbolic expressions. NZ Maths Curriculum - Number and Algebra Level 3

Resources Needed:

• Whiteboard and markers
• Worksheets with exercises and problems (prepared in advance)
• Mathematical symbols cards
• Pencils and erasers
• Access to NZ Maths website for additional resources and problem sets

Lesson Outline:

Introduction (10 minutes)

1. Warm-up Activity: Begin with a number sequencing game where students identify patterns and complete sequences.
2. Introduction to Algebra Concepts: Explain what algebra is and its importance in mathematics. Use simple terms, describing algebra as a way of finding out unknown numbers by using symbols.

Main Activity (25 minutes)

1. Basic Algebraic Expressions:
   • Explain the concept of variables using everyday examples (e.g., having 'x' number of apples).
   • Introduce simple expressions like (x + 5 = 10). Discuss how to find out what 'x' could be.
2. Group Practice:
   • Distribute mathematical symbols cards and worksheets.
   • Students work in small groups to formulate and solve simple expressions from given problems (e.g., "If I have (x) candies and I eat 5, now I have 8 candies left, how many did I start with?").
   • Guide students through forming equations based on the worksheets provided.

Consolidation (10 minutes)

1. Review Worksheet Problems:
   • Review a few problems as a class, solving them on the whiteboard, and ensuring understanding of the solutions.
2. Discussion:
   • What did the students learn about using symbols and solving for unknowns?
   • Discuss any difficulties students encountered and how they overcame them.

Assessment:

• Observe student participation during group work.
• Review the completed worksheets to assess understanding and correct application of algebraic concepts.

Follow-up:

• Assign additional practice problems from the NZ Maths website to reinforce today’s lessons.
• Plan a more advanced session on algebraic expressions and introduce multiplication and division equations.

Notes for Next Lesson:

Prepare to introduce and explore multiplication and division in algebraic expressions, expanding the students' understanding and application of algebra.
