KS2 SAT Booster: Rounding Rounding has been a very popular subject ever since the KS2 Maths SATs started all those years ago, and the subject is still cropping up in recent papers. The examiners try to make it hard by asking for the same number to be rounded to the nearest 100, 1 000 and 10 000. We have plenty of practice for this type of question in our unbeatable KS2 Maths Booster category – an absolute must for any children taking the tests this year. Go to KS2 Booster Rounding
