Overview

This 50-minute lesson aims to teach Year 8 students how to approximate numbers by rounding them to the nearest 10 and 100, aligned with the National Curriculum for England (Mathematics - Number: Number and place value). The lesson is designed for a class of 12 students following Functional Skills Maths (Entry Levels and Level 1), with varied differentiation strategies to support diverse learners.

National Curriculum Reference

Key Stage 3 - Year 8
Number: number and place value

• Use approximation and estimation to check answers to calculations and determine, in the context of a problem, levels of accuracy (NC Code: 3NPV)
• Round any whole number to a required degree of accuracy (NC Code: 3NPV)

---

Learning Objectives (WALT)

• WALT round whole numbers to the nearest 10.
• WALT round whole numbers to the nearest 100.
• WALT use rounding to approximate calculations and check reasonableness.

---

Success Criteria

• I can identify which digit to round to when rounding to 10 or 100.
• I can round any whole number to the nearest 10 correctly.
• I can round any whole number to the nearest 100 correctly.
• I can explain why rounding is useful in everyday scenarios.

Resources

• PowerPoint presentation (15 slides)
• Worksheets (3 differentiated levels)
• Whiteboard and markers
• Number cards (0-9) for interactive rounding games
• Mini-whiteboards for student responses

Lesson Activities

Starter (10 minutes)

• Engagement: Show slide 1 with an everyday context (e.g., money in a wallet, distances, or ages). Ask students: "Why might we need to round numbers in everyday life?"
• Quick input: Introduce rounding rules with a simple rhyme ("5 or more, up you go! 4 or less, stay down low!") using slides with visual numbers. Use number lines on slides to reinforce visual understanding.

Main Teaching (20 minutes)

• Whole-class demonstration:
  • Slide 5-8: Explain rounding to nearest 10 with examples. Ask questions: "What is the digit in the tens place?" "What digit comes after it?"
  • Slide 9-12: Explain rounding to nearest 100 similarly, using larger numbers.
• Guided Practice:
  • Use number cards to physically form numbers on student desks. Call out a number, and students round it aloud and write answers on mini-whiteboards.
  • Use a number line on the whiteboard to place numbers and check rounding visually.
• Pair work - Worksheet 1 (Support): Focus on numbers rounding to 10 only.
• Individual work - Worksheet 2 (Core): Mix of rounding numbers to 10 and 100.

Plenary and Assessment (15 minutes)

• Quiz game on PowerPoint: Multiple choice questions round the room, where students vote on answers.
• Success Criteria Review: Checklist on slide summarising key skills. Students self-assess progress.
• Extension activity (Worksheet 3) available for advanced learners who finish early: Problems estimating sums or differences after rounding.
• Formative Assessment: Teacher collects completed worksheets and observes student responses during mini-whiteboard tasks for immediate feedback.

Differentiation Strategies

Learner Type	Adaptations
SEN / Lower Ability	Worksheet 1 with simpler numbers, step-by-step instructions with images, use of manipulatives (number cards), paired support
EAL Learners	Key vocabulary displayed with visuals and examples, use of bilingual glossaries if needed, oral repetition and role play rounding scenarios
Advanced Learners	Worksheet 3 extension with multi-step problems and estimation in problem-solving, encourage explaining reasoning verbally or in sentences
Functional Skills Focus	Real-life contextual examples (e.g., shopping, measurement), use of practical rounding activities that relate to entry-level competencies

Summary

This lesson plan carefully targets Year 8 Functional Skills students by using a combination of visual, tactile, and verbal teaching methods aligned to the national curriculum’s specific learning objectives on rounding. Differentiation ensures accessibility and challenge, and interactive elements engage the small class size while allowing formative assessment to inform next steps.
