Maths by the end of Yer 3

[Mandzi34]

DD is currently in Year 3. Can anyone tell me what they should be able to do in terms of adding /subtracting by the end of Year 3. Ie three digit numbers or four digit numbers? With working out shown.

All explained here - National Curriculum

Thanks!

I'd be expecting a secure written method for addition and subtraction of 3 digit numbers using whatever the school's chosen method is and being mentally able to add and subtract 3 digit numbers and multiples of 1, 10 and 100.

Thank you. That's really helpful.
