Exploring Number Bonds

Overview

This 30-minute lesson is designed for Year 2 students, including those with Special Educational Needs (SEN), focusing on understanding and practising number bonds to 10 and 20. It aligns with the National Curriculum for England's Programme of Study in Mathematics: Number – Addition and Subtraction.

National Curriculum Reference

Key Stage 1: Mathematics - Number – Addition and Subtraction

• Year 2:
  • Pupils should be taught to recall and use number bonds to 20 and related subtraction facts within 20.
  • Solve problems with addition and subtraction using concrete objects and pictorial representations, including those involving numbers, quantities and measures.

---

Learning Objectives

By the end of this session, pupils will:

1. Confidently recall number bonds to 10 and 20.
2. Use concrete objects to make and explore number bonds.
3. Apply number bonds knowledge to solve simple addition and subtraction problems.

Key Competencies

• Fluency with number bonds within 20.
• Use of physical manipulatives for conceptual understanding.
• Communication and reasoning skills through explaining findings.
• Engagement through tactile and visual learning suitable for SEN needs.

Resources

• Counters or coloured beads (at least 20 per student).
• Number bond mats (paper mats divided into two circles connected to a total circle).
• Velcro-backed number cards (numbers 1 to 20).
• Large number bond display board.
• Whiteboards and markers for each student.
• Timer or stopwatch for interactive games.

Lesson Structure

1. Introduction (5 minutes)

• Greet students and briefly explain today's activity: “We are going to explore how numbers can be made in different ways using counters.”
• Show a large number bond display with numbers to 10 and review with the class the concept of two numbers making a whole (e.g., 7 and 3 make 10). Use clear, simple language.
• Ask volunteers to come and demonstrate adding two numbers with counters on the mat.

2. Main Activity: Hands-On Exploration (15 minutes)

• Distribute individual number bond mats and counters to each pupil.
• Give number cards showing a target number (start with 10, move to 20).
• Students work individually or in pairs to build all the possible number bonds for the target number using counters and place the correct number cards on their mats. For example, for 10: 1 and 9, 2 and 8, 3 and 7, etc.
• Teacher models one example at the front for the class as guidance.
• Encourage SEN students by pairing them with a teaching assistant or peer buddy and using visual/tactile prompts like coloured counters separated by colour to make bonds clearer.
• Use a gentle timer for each target number to encourage engagement but keep pressure minimal.
• Circulate the room giving personalised support, praise, and asking guiding questions like: “How many more do you need to make 10?” or “What happens if you add one more counter here?”

3. Interactive Game: “Number Bond Race” (7 minutes)

• Arrange students in a circle or semi-circle.
• Teacher shows a number card (e.g., 20).
• Students take turns saying one possible pair that makes 20 from memory or using hand gestures (e.g., “15 and 5”).
• Each correct answer lets that student move one step forward (on a simple floor track marked with tape).
• SEN students are encouraged to use counters as prompts or answer verbally with support.
• Celebrate progress with claps and encouraging words.

4. Plenary and Assessment (3 minutes)

• Quick round of “Show me” on whiteboards: teacher calls out a target number and students write pairs that make that number.
• Teacher observes ability to recall and apply number bonds and gives instant, positive feedback.
• End with a group reflection: “What did we learn about number bonds today?”
• Note down any pupils needing further support or challenge for future lessons.

Differentiation Strategies

• For SEN pupils: Provide additional multisensory resources (e.g., textured counters), paired working, step-by-step prompts and frequent breaks.
• For more able students: Challenge with number bonds beyond 20, or ask them to create their own ‘number bond problems’ for the class to solve.
• Use visuals, repetition, and physical movement to maintain focus.

---

Evaluation and Follow-up

• Monitor individual student’s confidence recalling number bonds during the lesson and note progress.
• Use observations to plan follow-up sessions: additional practice for those struggling and extension activities for fluent pupils such as related subtraction facts or word problems.
• Share insights with SENCO and support staff to adapt resources further where needed.
