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.

Odd and Even number demonstration…

EY’s activity Turn to the partner next to you. What even things do they have? And what odd things do they have?

Odd Numbers: Stand up (Like Popcorn) Even numbers: Sit down 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. 13 14 9 15 8 1 5 20 6 11 Odd Numbers Even numbers By A. Gore

Let’s sort some more numbers into odd and even boxes. 81 164 49 95 38 83 130 56 227 Odd Numbers Even numbers By A. Gore

Main activity & Plenary …

Did you know? If you double an odd number the answer is always an even number. You try it!

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.
