About this worksheet
Each worksheet has 16 problems rounding two integers and estimating their sum or difference.
This worksheet asks for an estimate rather than an exact answer, using signed numbers. Every problem names the place to round to, because an estimate of a sum has no single right answer until that is said. At least one number in every problem is negative, so the rounding is the easy half and deciding which side of zero the answer lands on is the half that matters. Sheets can be customized, turned into flash cards, or assigned for online learning.
