Our final mathematics and numeracy activity this week is odd and even numbers!


As a warm up activity recall those two's numbers again. You can use the song from yesterday as a fun introduction. It also has at the beginning a line which emphasises the two's numbers from 1-10. You could pause the video at this point and recite them together making the point that you say one out loud and the other numbers (1,3,5,7,9) all stay silent. 


Then look back at the hundred square that you made yesterday. Say that for the two's squares that were coloured in you are going to shout them and for the ones not coloured in (1,3,5,7,9) you are going to say the quietly. You can do this together. 


Once completed explain to your child that there are special name for the loud numbers that we count in two's from and a special name for the quiet numbers - odd (1,3,5,7,9) and evens (2,4,6,8,10). 


Now to sort!

Give your child a set of number cards to 10, 20 if they are confident with numbers to 10. Then ask them to sort them into two groups - odds and evens. If you have trays, hoops, chalk or masking tape so you can create two sorting groups that would be useful, but not essential. It would be good however to label the groups with 'odds' and 'evens' so that they can become familiar seeing those maths words.  Let them sort! Any errors that they make then supportively work through it with them to find out if their answers are correct.  Now, to be a great mathematician, ask them to explain how they worked it out!



Need a stepping stone?

Your child may find this activity challenging if they aren't confident with numbers to ten or are finding counting in two's tricky. Don't worry. Spend your time today building on what you did yesterday. Practise, practise, practise counting in two's. If you manage it complete yesterdays activities transferring counting in two's onto a hundred square and seeing if you can spot patterns.  We can come back to odds and evens later in the year when they are ready for it.


Need a further challenge?

If your child understands this then you can continue to explain that with even numbers you can share between two people and they will have the same amount, but with even numbers it become more tricky to that. You can practise this with objects up to 10. Find a number and share it out between two people or teddies...they will visually see that they get the same amount.
