About this worksheet
Each worksheet has 16 problems estimating a sum or difference of mixed numbers by rounding to the nearest whole number.
This worksheet estimates a sum or difference of mixed numbers by rounding each to the nearest whole number - four and five sixths minus two and one eighth is about five minus two. It is the mixed number half of the standard, alongside the sheet that rounds proper fractions to benchmarks. A fractional part near one half never appears, since nearest whole would then have two right answers. Sheets can be customized, turned into flash cards, or assigned for online learning.
