Year 1 maths worksheet: subtraction

It has been a while since I published anything for year 1, so here are a couple of pages on understanding subtraction. They look very straightforward but there are a number of concepts involved here:

Firstly, understanding that the phrase, ‘How many are left’ .

Secondly, relating subtraction to ‘taking away’.

Thirdly, the answer can be found by counting up from a number.

Fourthly, the answer can be found by counting back from the larger number.

Finally, that the minus sign means subtract.

Thanks to urbrainy.com for letting me use these two pages.

How many are left?
