Counting in Twos

Learning Objectives

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

• Count forwards and backwards in twos, starting from 0 and from any given even number within 20.
• Recognise and use the pattern of counting in twos to solve simple problems.
• Understand counting in twos as 'pairs' and connect this with doubling.

National Curriculum reference:

• Mathematics: Number – Number and Place Value – Year 1
• Pupils count to and across 100, forwards and backwards, beginning with 0 or 1, or from any given number.
• Pupils count in multiples of twos, fives and tens.

Resources

• Number line posters (0 to 20) prominently displayed
• Counters or small cubes (at least 60, grouped in pairs)
• Large paired objects (e.g. pairs of socks, toy animals in pairs)
• Whiteboards and markers for each pupil
• Interactive whiteboard or projector for visual patterns
• “Counting in Twos” song audio or video (optional)

Lesson Structure (45 minutes)

1. Introduction (5 minutes)

• Greet the class and explain that today they will learn to count in twos.
• Begin with a quick warm-up counting from 0 to 10 together.
• Ask: "How many fingers do you have? Can you count them in pairs?"
• Show pairs of objects (e.g., two socks) and elicit “two” and “four” when you show two pairs and so on.

2. Demonstration and Guided Practice (10 minutes)

• Use a large number line 0 – 20 displayed on the board.
• Point to numbers as you count in twos aloud: 0, 2, 4, 6, 8, 10, 12, 14, 16, 18, 20.
• Emphasise the pattern of the last digit (0, 2, 4, 6, 8).
• Use counters in pairs to physically place on the number line or on desks — 1 pair = 2 counters, 2 pairs = 4 counters, etc.
• Invite volunteers to come and place pairs of counters at the correct number on the line as counting progresses.

3. Practical Activity: Pair Counting (10 minutes)

• Pupils work in pairs with groups of counters or cubes.
• Challenge: Make pairs and count aloud in twos up to 20 (e.g., 2, 4, 6, 8, 10).
• Then reverse: start from 20, break down into pairs while counting backwards in twos — 20, 18, 16...
• Circulate and support children who find it challenging.
• Extension: Use everyday objects in the classroom to find pairs and count them in twos together (e.g., pairs of shoes, pencils, etc.).

4. Fun Group Game: “Hop Along Twos” (10 minutes)

• In the classroom or outdoor space, create a hopscotch grid numbered 0 to 20 in twos (0, 2, 4,...20).
• Children take turns hopping to each number while counting aloud in twos.
• For added challenge, children try hopping backwards from 20 to 0 counting in twos.
• Use enthusiastic praise and encourage children to clap and cheer as peers count.

5. Consolidation and Assessment (8 minutes)

• Hand out mini whiteboards and markers.
• Call out various starting numbers that are even: 0, 4, 8, 10.
• Ask pupils to write the next three numbers counting in twos (e.g., from 4: 6, 8, 10).
• Check their responses and provide immediate praise or support.
• Ask targeted pupils verbally to count in twos starting from a given number to check verbal fluency.

6. Plenary and Reflection (2 minutes)

• Recap the pattern of counting in twos and its usefulness (doubles and pairs).
• Ask: "Can anyone tell me one place we might see counting in twos in everyday life?"
• End with a quick “Counting in Twos” song or chant to reinforce learning.

Assessment

Formative assessment throughout the lesson:

• Observation during practical activity and the hopscotch game: Are children accurately counting in twos and recognising the pattern?
• Responses on mini whiteboards: Correct sequencing of numbers in twos starting at different points.
• Verbal questioning during plenary for understanding beyond rote counting.

Next steps if pupils struggle:

• Use more manipulatives to visualise pairs.
• Scaffold counting starting from zero before moving to alternate starting points.
• Provide additional one-to-one support with practical pairing and counting.

Differentiation

• Support: Provide counting sticks with pairs marked and one-to-one adult help to scaffold counting.
• Extension: Challenge confident pupils to count in twos beyond 20 or explore counting in twos starting from odd numbers, discussing what happens.

This lesson plan uses hands-on activities, physical movement, and clear visual patterns to engage Year 1 pupils in understanding and mastering counting in twos. The use of manipulatives and real-life objects aligns with the National Curriculum focus on practical and visual number sense, ensuring a solid foundation for future multiplication and skip-counting skills.
