Determine if an Estimate is an Overestimate or Underestimate
Determine if an Estimate is an Overestimate or Underestimate is a skill on Pengi from Lesson 2: Estimate Sums and Differences of Decimals in enVision, Mathematics, Grade 5.
Key Concepts
To determine if an estimate is an overestimate (greater than the actual answer) or an underestimate (less than the actual answer), analyze how each number was rounded. Addition: If both numbers are rounded up, the sum is an overestimate. If both are rounded down, the sum is an underestimate. Subtraction ($A B$): If $A$ is rounded up and $B$ is rounded down, the difference is an overestimate. If $A$ is rounded down and $B$ is rounded up, the difference is an underestimate.
