National Numeracy Strategy Block A1: Counting, Partitioning and Calculating.
Duration
45 mins - 1 hour
Learning objectives
-
Children will be able to describe and extend number sequences and recognise odd and even numbers.
Resources
-
Number crunchers - all audio tracks
-
Pre-prepared worksheet: Odds and Evens (see the Main activity and the Independent activity for details of what to include in the worksheet)
-
Interactive Whiteboard and SMART Notebook software (optional)
-
Number flashcards
Introduction
-
Share the Learning objectives with the children at the start of the session.
-
Show the children a number scale from 1 to 20, highlighting in one colour all of the odd numbers, and in another colour all of the even numbers. (This could be done using SMART Notebook software on the Interactive Whiteboard.)
-
Discuss the pattern of odd and even numbers, eg. numbers ending in 0, 2, 4, 6, 8 are even and numbers ending in 1, 3, 5, 7, 9 are odd.
Prior Learning
-
Children should be able to read and write two- and three-digit numbers in units and words and fit these numbers into a sequence
Main activity
-
Explain to the children that they are going to learn a song called Number crunchers.
-
Play the song through a few times encouraging the class to join in and learn all of the words.
-
Ask the class questions such as ‘Is the number six odd or even?’. Children can then use the song to work out the answers.
-
Ensure that the number scale is available for children to see throughout the lesson so that they can refer to it if they need to.
Independent activity
-
Hand out a pre-prepared worksheet on number sequences and odd/even numbers. The worksheet should focus on counting on from a given number sequence and identifying odd and even numbers, for example:
‘Can you count on in twos from this sequence:
2, 4, 6, _ _ _ ?’
‘Are these numbers odd or even ... ?’
‘Count up in threes from this sequence: 5, 8, 11, _ _ _’
‘Can you circle all of the odd numbers in this sequence ... ?’
Differentiation
Support
-
Group the children in mixed-ability pairs/groups.
-
Offer more prompts of support to the less able.
Extension
-
Children to complete more advanced number sequences involving two-digit numbers eg. 14, 17, 20 ... (what are the next three numbers in this sequence? Circle the odd/even numbers) etc.
Plenary
- Listen to and sing through Number crunchers again. Using flashcards, hold up a number and ask the class to identify whether it is odd or even.
Assessment for learning
Can the children:
-
Differentiate between odd and even numbers?
-
Count in fives from 0 to 30?
-
Say which of these numbers are odd/even and explain how they know this?
Next steps
- Children learn how to count to 100 by grouping numbers, eg. in tens, fives and twos. Explain what each digit represents in a two-digit number, eg. the 2 tens and the 1 unit in the number 21.
Differentiated success criteria
All children will:
-
Be able to recognise odd and even numbers up to and including ten.
Some children will:
-
Be able to complete number sequences.
-
Be able to say whether a given number is odd or even.
A few children will:
-
Be able to explain how they can tell that a given number is odd or even.

brilliant way to teach the little children!
