Estimate the sum in two different ways:

A) By rounding off to the highest place value (hundreds):
  368 = 400  (3 hundreds is the highest place value)
  231 = 200 (2 hundreds is the highest place value)
  
  400 + 200 = 600

B) By rounding off to the second highest place value (tens):
    368 = 370
    231 = 230
   
    370 + 230 = 600
