Transcript Odd and Even

Odd or Even?
If a number can be shared equally
by two, and has a partner, it is an
even number.
If a number can’t be shared equally
by two, and there is one by itself,
then it is an odd number.

EY’s activity
Turn to the partner next
to you. What even things
do they have? And what
odd things do they have?
Year 1 Starter Activity
Now we’re going to play a game to decide if it’s an odd or an even number.
Odd Numbers: Stand up
(Like Popcorn)
Even numbers: Sit down
Let’s sort some numbers into
odd and even boxes.

Did you know?
If you double an odd
number the answer is
always an even number.

EYFS Curriculum
40-60+ months •
A Unique Child: Observing what the child is learning
• Recognise some numerals of personal significance.
• Recognises numerals 1 to 5.
• Counts objects to 10, and beginning to count beyond 10.
• Counts out up to six objects from a larger group.
• Counts an irregular arrangement of up to ten objects.
Positive Relationships:
• Encourage estimation, e.g. estimate how many sandwiches to make for the picnic.
• Encourage use of mathematical language, e.g. number names to ten: ‘Have you got enough to give me three?’
• Show interest in how children solve problems and value their different solutions.
• Use mathematical vocabulary and demonstrate methods of recording, using standard notation where
appropriate.
Enabling Environments
• Provide collections of interesting things for children to sort, order, count and label in their play.
• Use tactile numeral cards made from sandpaper, velvet or string. • Create opportunities for children to
experiment with a number of objects, the written numeral and the written number word. Develop this through
matching activities with a range of numbers, numerals and a selection of objects.
• Use a 100 square to show number patterns.
• Provide a wide range of number resources and encourage children to be creative in identifying and devising
problems and solutions in all areas of learning.
National Curriculum
Knowledge, Skill and Understanding
Communication
1e - use the correct language, symbols and vocabulary associated with number and
data
1f - communicate in spoken, pictorial and written form, at first using informal language
and recording, then mathematical language and symbols
Reasoning
1h - understand a general statement and investigate whether particular cases match
it
Numbers and the Number System
Number patterns and sequences
2b. create and describe number patterns; explore and record patterns related to
addition and subtraction, and then patterns of multiples of 2, 5 and 10 explaining the
patterns and using them to make predictions; recognise sequences, including odd
and even numbers to 30 then beyond; recognise the relationship between halving
and doubling
Processing, representing and interpreting data
5a. solve a relevant problem by using simple lists, tables and charts to sort, classify
and organise information
5b. discuss what they have done and explain their results.
