The mistakes behind most wrong answers
A wrong answer in rounding to tens and hundreds is rarely random. These are the ones that come up most often, each on a real problem — worth knowing before you mark a sheet, because the fix for each is different.
Round 750 to the nearest hundred.
750The answer is 800. A child who answers 900 probably counted one group too many or too few.
Round 945 to the nearest ten.
945The answer is 950. A child who answers 900 probably rounded to the wrong place.
Round 205 to the nearest ten.
205The answer is 210. A child who answers 200 probably chopped the digits instead of rounding.
