Lesson Plan: Number, Money, and Measure - Constant and Variable Quantities

Grade Level: Fourth Level (Scottish Curriculum)

Topic: Number, Money, and Measure - Constant and Variable Quantities

Desired Outcome: Having explored how real-life situations can be modeled by number patterns, I can establish a number sequence to represent a physical or pictorial pattern, determine a general formula to describe the sequence, then use it to make evaluations and solve related problems.

Lesson Duration: 60 minutes

Resources: - Whiteboard or blackboard - Markers or chalk - Worksheets with number patterns and related problems - Calculators (optional)

Introduction (10 minutes): 1. Begin the lesson by asking students if they have ever noticed patterns in numbers or sequences in their daily lives. 2. Discuss with the students some examples of patterns they may have observed, such as counting by twos, threes, or fives, or the Fibonacci sequence. 3. Explain that today, they will be exploring number patterns and how they can be used to solve real-life problems.

Development (35 minutes): 1. Write the following number pattern on the board: 2, 4, 6, 8, 10, … 2. Ask the students to identify the pattern and determine the rule or formula that generates the sequence. 3. Guide the students to recognize that the pattern is increasing by 2 each time, and the rule or formula is “add 2.” 4. Write the formula on the board: n + 2, where n represents the position of the term in the sequence. 5. Provide additional examples of number patterns and guide the students to determine the formula for each pattern. 6. Distribute worksheets with various number patterns and related problems. 7. In pairs or small groups, ask the students to work on the worksheets, identifying the patterns, determining the formulas, and solving the related problems. 8. Circulate around the classroom, providing support and guidance as needed.

Conclusion (15 minutes): 1. Bring the class back together and discuss the solutions to the problems on the worksheets. 2. Ask students to share their strategies for determining the formulas and solving the problems. 3. Emphasize the importance of recognizing patterns and using formulas to solve real-life problems. 4. Summarize the lesson by restating the desired outcome: “Having explored how real-life situations can be modeled by number patterns, I can establish a number sequence to represent a physical or pictorial pattern, determine a general formula to describe the sequence, then use it to make evaluations and solve related problems.” 5. Encourage students to continue exploring number patterns and applying formulas in their everyday lives.

Assessment: - Observe students’ participation and engagement during class discussions and group work. - Review students’ completed worksheets to assess their understanding of identifying patterns, determining formulas, and solving related problems. - Provide feedback and guidance to individual students as needed.
