This week we are going to re-cap some addition and subtraction strategies.
In class we spent a lot of time learning the pairs of numbers that add to make 10. We need to know these as they are the important for knowing pairs of numbers that add to 100 and1000 too. E.g. if 5+5=10 then 50+50=100 and 500+500=1000.
1)To start, today. I want you to begin by listing as many ways of making 10 as you can.You should start by listing all the number bonds to 10 (remember there were 11 including the switcheroos!)
As well as the number bonds to 10, you can list subtraction sums too e.g. 18-8=10 or bigger: 88-78= 10.
2) Once you have warmed up your maths brain, have a go at the list of missing number additions opposite. There is a pattern that you will start to notice!

1) Set the work out like this:
We have looked at number trios before where we can use 3 numbers and make lots of sums from them. E.g 2 8 10
We can also use these numbers to help us with larger sums e.g.
Today we are going to explore these number relationships. Watch the video and then have a go at the worksheet opposite.
You can print the sheet or copy the sums down onto a page split into 4 if you like.
Today we are going to practice adding a 1 digit number to a 2 digit number. E.g. 48 + 6.
Remember that we have practiced strategies such as counting on (putting the large number in your head then counting on with objects or fingers).
You will need a dice today but if you don't have one, you could make a pack of number cards 1-6 or use the online dice opposite:
You don't need to print out the sheet. You could complete the activity in a book by copying the numbers and completing the additions.
|Thursday||We have looked at some difference aspects of addition and its relationship with subtraction this week. Now it is time to have a go at some word problems. Remember how we can move numbers around within a number trio to create new sums but the sums still need to make sense. E.g. if 30-20=10 I cannot write 20-30=10 because I cannot take 30 away if I only have 20. The sum still needs to make sense. Have a go at the activity opposite and remember that a number sentence always has to make sense.||https://www.j2e.com/lansdowne-primary-school/Mrs+Evans/word+prob+pt.pdf/|
