Children in Key Stage 1 need to learn about odd and even numbers.
An even number is a number that can be divided into two equal groups.
An odd number is a number that cannot be divided into two equal groups.
Even numbers end in 2, 4, 6, 8 and 0 regardless of how many digits they have (we know the number 5,917,624 is even because it ends in a 4!).
Odd numbers end in 1, 3, 5, 7, 9.
Teachers will often give children counters to help them understand odd and even numbers. They may give children a set of numbers, for example:
7 1 8 4 5
and then ask them to count out each number in counters, then organise the counters into two equal groups. Sometimes it is helpful to give them a piece of paper with two circles on it, so that they can count the counters out into the circles.
Give your child some socks and ask them to put them into pairs. Is the number odd or even? How do they know? Try this a few times with a different amount of socks each time.
For the basketball game below:
Yellow and red group choose numbers to 99
Green and blue group choose numbers to 29 (if you child is doing well choose higher numbers) Again please do give them as much support as you feel is needed.
