Yr R Maths activities for week commencing 22nd June

This week we are going to continue looking at halving and the numerical pattern of odds and evens.
The children will do this through practical activities where they have to sort a quantity of objects by sharing them into two equal groups, investigating which can be shared and which can’t.
Your child will begin to understand that quantities which can be shared into two equal groups with no items left over are even. Those which have left over when they are shared into 2 equal groups are odd.

Monday 22nd June
Provide your child with some toys that they can use for sharing, for example, farm animals and two fields or toy cars and two carparks. Encourage them to explore which quantities can be shared and which have one left over. Explain that when we can share between 2 fields/2 carparks with none left over, these numbers are known as ‘even numbers’. Those which have an item left over and can not be shared are called ‘odd numbers’. Write the words ‘even’ and ‘odd’ on the top of a piece of paper and ask your child to keep a record of their numbers. (please ensure your child only works with numbers that they are secure with, ie numbers up to 10 before moving on to numbers to 20)

Tuesday 23rd June
Remind your child of the halving activity that they did yesterday. Can they remember what ‘even numbers’ are and what ‘odd numbers’ are? Have a quick re-cap. Provide your child with a number line from 1 to 10 and some counters. Ask them to identify the first number on the number line. Take this number of counters. Can they halve/share it? Is it an odd or even number? Repeat for all the numbers on the number line. Choose one colour pen for odd and a different colour for even. Circle each number on the number line according to whether they are odd or even. Ask your child what they notice about the pattern. Extension: If your child is confident ask if they can continue the pattern to 20 and check using objects and sharing.

Wednesday 24th June Watch ‘Six dinner Sid’  Discuss the story with your child. Go on a short walk and look at the house numbers. Identify whether they are odd or even. What do you notice about how they are arranged? (Quite often odds are on one side of the road and evens on the other). Make your own street and number the houses. Place the odds on one side and the evens on the other. Make your own Sid. How many dinners will he eat? How many houses will he go to? Allow your child time to play and discuss the houses Sid visits. Are they odd or even numbers? How do they know?

Thursday 25th June Watch Numberblocks series 2 episode 11 odds and evens  Can you make your own number blocks? Can you put them into two teams, the ‘even tops’ and the ‘odd blocks. Maybe you could use Lego bricks. Think about which bricks to use that will show an even or odd number.

Friday 26th June Watch Numberblocks series 2 episode 11 odds and evens again  Using the print outs of the numberblocks, sort the blocks into ‘odd blocks’ and ‘even tops’. Look at the ‘odd tops’. Can you make them into ‘even tops’ by adding two together? Which even number will you make? Extension: Write the number sentence and the part whole model to go with it.  (halves to 10)  (halves up to 10)

Please continue to play on ‘Numbots’ and ‘Maths Factor’.
