Autumn 1


During this half term, we have mostly looked at place value and addition and subtraction. It is really important that children understand how the number system works and how to make 10. We learnt a song to help us with number bonds to 10, to the tune of 'Row, row, row your boat':


9 and 1 are number bonds,

8 and 2 are friends,

7 and 3,

6 and 4,

5 and 5 are twins!


When we look at 2-digit numbers we have been learning to identify how many ones and how many tens the numbers have. We know that the number 24 is made of 2 tens and 4 ones; the number 24 is the same as 20+4.



We have also been using our knowledge of number bonds to help us with addition that bridges the 10s boundary. 

When adding a 1-digit number, we first partition the number to create a new complete ten. In 17+5, we partition the 5, using 3 to add to 17 to create a complete ten (20), which then leaves 2 of the next ten. Therefore 17+3 = 20+2 = 22



We have also used number lines to support children with addition and subtraction. Children have been working on remembering to make their first jump along the number line when they say 'one' - a common error is to count the number they are starting from!

Autumn 2


We have been using place value grids to help us use equipment when making and adding 2-digit numbers. 

We used it first when our numbers didn’t bridge ten.



We practiced adding the ones and then the tens. 

31 + 23 = 54

Spring 1


We have started looking at arrays this terms. 

We have learnt that the x symbol means "groups of"


Using this language and drawing a picture will help us work out a calculation.


e.g. "2x2" is the same as "2 groups of 2", and you could draw  o o 

                                                                                                o o

We then used this knowledge to solve problems.
