Grouping Through Numbers

Overview

This 25-minute lesson develops Reception pupils’ understanding of grouping objects to solve simple number problems, directly reflecting the Early Learning Goal in the National Curriculum for England under Mathematics: Number – Numerical Patterns. Pupils will explore grouping concrete objects, practise problem solving in small groups, and reflect through talk tasks supported by manipulatives.

Curriculum Links

• Mathematics: Number – Numerical Patterns
  ELG: Children count reliably with numbers from 1 to 20, place them in order and say which number is one more or one less than a given number. Using quantities and objects, they add and subtract two single-digit numbers and count on or back to find the answer.

• Development Matters 40-60+ Months Goals

  • Count objects, actions and sounds.
  • Subitise (recognise quantities without counting) up to 5.
  • Solve problems, including sharing and grouping.

Learning Objectives

By the end of the lesson, pupils will:

• Understand how to make equal groups with concrete objects to solve a problem.
• Use language related to grouping, such as “groups of”, “more”, “less”, “equal”.
• Practise counting in groups and recognise simple groupings within numbers up to 10.
• Verbally explain their method during an independent talk task.

---

Resources

• Small objects for grouping: counters, buttons, teddy bears, building blocks (enough for each pupil)
• Grouping mats with circles drawn or trays divided into sections
• Number cards 1-10
• Large visual number line (1-10) at board level
• Whiteboard and marker for teacher demonstrations

Lesson Outline (25 minutes)

1. Introduction & Engage (5 minutes)

• Gather pupils on the carpet and introduce the concept: “Today we are going to make groups of objects to help us solve number problems.”
• Model with small teddy bears: Place 6 bears on the mat. Ask, “Can we make equal groups? How many groups can we make?”
• Demonstrate one grouping: “6 bears can be put into 2 groups of 3.” Count aloud together: 3, 6.
• Show groups clearly and use fingers/point to reinforce counting.

2. Modelled Examples with Grouping Mats (7 minutes)

• Present several different examples, starting very simple and building:

• 4 counters → Can we make 2 groups? (2 + 2)
• 5 buttons → Can we make groups of 1 or groups of 2? What happens? (One group of 2 plus another group with one leftover)
  • Act out and count each time with the children. Emphasise vocabulary “groups of” and “leftover”.
  • Write simple number sentences on the board alongside grouping, e.g., 2 + 2 = 4, 2 + 2 +1 = 5 (for higher attainers).
  • For pupils needing more support, use fewer objects and allow them to physically move the counters to create groups.

3. Active & Interactive Group Work (8 minutes)

• Split the class into small mixed-ability groups (3-4 pupils), each with a set of objects and a grouping mat.
• Present a simple challenge verbally or with picture cards, e.g., “Can you make 3 groups using 9 counters?” or “How many groups of 2 can you make with 8 blocks?”
• Children physically place objects in groups, count aloud with peers, and check their results together.
• Teacher circulates to scaffold: ask leading questions ("How many in each group? Are your groups equal? What if you try a different number?") and support.

4. Independent Talk Task (4 minutes)

• Pupils choose one of their groupings to explain to a partner:

• Prompt questions for talk: “How many groups did you make? How many objects in each group? What was the total?”
  • Encourage use of the new vocabulary and counting.
  • For pupils who need extra support, allow using objects to demonstrate while they talk.

5. Plenary & Assessment (1-2 minutes)

• Gather pupils and ask a few volunteers to share their grouping aloud.
• Check understanding through quick thumbs up/down or nodding – e.g., “Did you all understand how to group objects?”
• Remind key vocabulary learned: group, groups of, equal, leftover.

Differentiation

Needs More Support	Working At Expected	Greater Depth
Use fewer objects (3-4) to group; focus on groups of 1 or 2. Manipulative-heavy support. Use visual cues and clear step-by-step modelling.	Provide standard problems with numbers 5-10; encourage counting and verbal explanation. Scaffold language use.	Introduce simple number sentences (addition) with leftover objects. Explore multiple grouping solutions. Encourage recording on whiteboards.

---

Assessment Opportunities

• Observe pupil participation in group work: Are they able to make equal groups and count accurately?
• Use the independent talk task to assess understanding of grouping concepts and vocabulary use.
• Check pupils’ ability to count objects within groups and reason about leftover objects or unequal groups.
• Teacher notes on any misconceptions (e.g., incomplete groups or counting errors) for future planning.

---

Notes for Teachers

• Use enthusiastic tone and plenty of praise to encourage risk-taking in problem solving.
• Keep physical movement frequent – pass objects around and encourage peer discussion.
• Highlight how grouping lays foundations for multiplication and division concepts in later years.
• Consider using themed objects (farm animals, candies) aligned to children’s interests to raise engagement.

This active, scaffolded approach provides Reception pupils with hands-on experience of grouping concepts, embedding number sense naturally within the Early Learning Goals and National Curriculum expectations.
