Remember when we subtract the number always gets smaller; we count backwards.
Minus, take-away, less than and subtract all mean the same thing.
Warm Up:
Go on a number hunt around your house. Can you identify the number before the number you find? Remember to find the number before, you must subtract 1.
Watch this subtraction video:
Main Task:
Write down your sums in your jotter and then answer them.
Primary 1 sums are in red and Primary 2 sums are in blue.
Primary 1
Primary 2
3 – 1 =
13 – 1 =
6 – 2 =
16 – 2 =
10 – 3 =
20 – 3 =
5 – 4 =
15 – 4 =
6 – 6 =
16 – 6 =
9 – 0 =
19 – 0 =
7 – 3 =
17 – 3 =
10 – 4 =
20 – 4 =
Extra Challenge:
Can you answer these missing number sums. Remember they are take away sums:
· 7 – ? = 7
· 9 – ? = 6
· 13 – ? = 10
· 10 – ? = 8
· 8 – ? = 0
· 17 – ? = 13
Game to Support Learning:
Play the game below to practise your addition and subtraction.
Today we are going to be learning about doubles and near doublese.g. if we know that 3+3 = 6then we can use this to work outthat 3+4=7 (it is a near double – you just add one more) .
Warm Up:
Watch and join with these double videos:
Can you tell your doubles to someone?
Main Task:
Write these double and near double sums in your jotter with your answers.
2 + 2 =
2 + 3 =
3 + 3 =
3 + 4 =
4 + 4 =
4 + 5 =
5 + 5 =
5 + 6 =
6 + 6 =
6 + 7 =
7 + 7 =
7 + 8 =
8 + 8 =
8 + 9 =
9 + 9 =
9 + 10 =
10 + 10 =
10 + 11 =
Extra Challenge:
Make up your own doubles, or near doubles, with bigger numbers eg. 20 + 20 = 40 so 21 + 20 = 41.

I hope you are all safe and well and excited to learn from home!
Please take the time to read the letter Miss Ferguson wrote in your home learning pack you got on Friday – this explains how the blog will work and may answer any questions you have at the moment.
I will try and make the lessons as straightforward as possible and ensure any links can be used on tablets/phones as well as desktop computers.
Obviously, with our class being a composite class, some of the work will differ for the Primary 1’s and Primary 2’s – please ensure you look out for the different activities for your child’s stage.
Take this opportunity to enjoy showing the people you live with how clever you are and what you have learned so far in p1/2. I can’t wait to hear how you all get on.
Primary 1’s: watch this video clip https://www.youtube.com/watch?v=ndj6D-cWseA Count forwards and backwards to 30. Try starting from a different number each time e.g. start at 19 and count up to 30 or start from 25 and count backwards to 0.
Primary 2’s: watch this video clip https://www.youtube.com/watch?v=Ss-azuApvA0 Count forward and backwards to 100. Try starting from a different number each time e.g. start at 49 and count up to 100 or start from 37 and count backwards to 0.
Main Activity:
Starting from 0, write your numbers in order. How far can you get?
Write each row of numbers in order, from smallest to largest.
Primary 1’s numbers are in red and the Primary 2 numbers are in blue.

Extra Challenge:
Make up your own maths problem.
Write down 4 numbers and then order them yourself or get someone else to order them.
Game to support learning:
Play the game below to practise ordering numbers.
Click on ‘ordering’ and then either 1-20 or 1-100.
