A sorting activity on odd and even numbers for Year 2 maths. Pupils sort sixteen numbers and sums, from 8 and 25 to 3 + 3 and 89, into odd and even columns, using the tip to check the ones digit of two-digit numbers. Two thinking questions follow, and the answer key covers everything. Linked to England National Curriculum place value objectives.
Number - number and place value
“Recognise the place value of each digit in a two-digit number (tens, ones)”
The ones-digit tip makes place value the sorting tool.
Number - number and place value
“Use place value and number facts to solve problems”
Sorting sums like 3 + 3 needs a calculation before the decision.
A short introduction with the tip: for a two-digit number, always look at the ones digit.
Sixteen numbers and sums, including 8, 25, 3 + 3 and 89, to write into odd and even columns.
Pupils say which item was trickiest to place, then add their own odd and even numbers.
Expected responses plus guidance for the open questions.
