Costing and Budgeting

Lesson Overview

This 45-minute lesson engages a Year 10 student in the practical skills of costing a fruit scone recipe, linked closely with budgeting and nutritional awareness. The activity develops mathematical skills through real-world application, aligned with the National Curriculum for England's Design and Technology and Mathematics programmes of study.

National Curriculum Links

Design and Technology (Cooking and Nutrition) - Key Stage 4 (Years 9-11)

• Understand and apply the principles of nutrition and health.
• Prepare and cook a variety of predominantly savoury dishes, including those with ingredients that require careful handling and preparation.
• Use knowledge of the characteristics and properties of ingredients to design and make products.

Mathematics - Key Stage 4 (Years 9-11)

• Solve problems involving ratio, proportion, and percentages.
• Calculate and compare costs, understand budgeting, and manipulate units of measure (e.g., grams, kilograms).

Learning Objectives

By the end of this lesson, the student will be able to:

1. Calculate the total cost of ingredients required to make fruit scones by sourcing prices from different supermarkets.
2. Compare and contrast ingredient prices from at least two sources to identify the most cost-effective options.
3. Explore how substituting ingredients (e.g., dried fruit varieties, fats) impacts the overall cost and nutritional value of the recipe.
4. Demonstrate understanding of budgeting principles in food preparation and the impact of ingredient choices on health and cost.

Success Criteria

• I can list the ingredients needed for fruit scones and their quantities.
• I can accurately calculate the total cost of ingredients from different price lists.
• I can suggest alternative ingredients and explain how they affect recipe cost and nutritional value.
• I can reflect on the importance of budgeting and making healthy choices when shopping for ingredients.

Resources Required

• Printed supermarket flyers or access to online supermarket price lists (real or simulated).
• A printed fruit scone recipe with ingredient quantities.
• Calculator or smartphone calculator app.
• Worksheet template for cost calculation and comparison.
• Nutrition information table for typical scone ingredients (dyslexia-friendly font).
• Pen and paper or digital device for recording calculations.

Lesson Structure

1. Starter (5 mins)

• Brief discussion: "Why is costing a recipe important?" and "How does budgeting affect our food choices?"
• Review the fruit scone recipe ingredients and quantities to ensure familiarity.
• Success criteria shared with student to clarify goals.

2. Main Activity Part 1: Costing Ingredients (15 mins)

• Provide multiple supermarket flyers / online price lists.
• Student locates and records individual ingredient prices from at least two different supermarkets.
• Calculate total estimated cost per supermarket source using multiplication and addition.
• Dyslexia-friendly printed price lists and clearly formatted worksheets are provided to aid comprehension.

3. Main Activity Part 2: Exploring Substitutions (15 mins)

• Present possible ingredient substitutions (e.g., replace butter with a lower-cost margarine, substitute raisins with sultanas).
• Student calculates impact on total cost of the recipe.
• Using provided nutrition info, student compares nutritional value of original vs substituted ingredients.
• Discuss impact of substitutions on health and cost.

4. Plenary (10 mins)

• Student summarises findings verbally or in writing: Which supermarket offered best value? How did substitutions affect cost and nutrition?
• Discuss implications for budgeting in everyday meal preparation.
• Teacher provides formative feedback based on success criteria.
• Extension challenge offered: Research own ingredient alternatives for another recipe or explore seasonal variations in pricing.

Differentiation Strategies

Learner Need	Approach
Dyslexia or reading difficulties	Use worksheets printed in dyslexia-friendly fonts (e.g., OpenDyslexic), use colour coding for pricing categories, and simplify instructions. Provide oral explanations and allow verbal recording of findings if preferred.
Mathematics challenges	Use step-by-step guided calculations and manipulatives (e.g., counters to represent cost units). Provide worked examples before independent tasks.
Advanced learner	Encourage investigation of more complex budgeting (e.g., bulk buying, discount offers) or analysis of nutritional content at micronutrient level.

---

Extension Activities

• Create a 1-week meal budget using a weekly supermarket flyer, factoring in cost, nutrition, and variety.
• Design a price comparison infographic for textbook-style presentation to inform wider school community about budgeting strategies.
• Explore the environmental and ethical impacts of substituted ingredients (e.g., imported vs local fruit).

---

Assessment Opportunities

• Formative assessment through worksheet accuracy on costing and substitution calculations.
• Verbal explanation and justification of choices during plenary (confidence and depth of understanding).
• Potential self-assessment against success criteria to foster reflection.

---

Teacher Notes

• Keep the session interactive by prompting the student to explain their thinking.
• Highlight the connection between mathematics and real-world living skills.
• Reinforce nutritional importance alongside economic considerations to promote holistic thinking in food technology.
• Use questioning to scaffold and deepen understanding, especially of budget constraints and healthy eating principles in line with national guidance.
