Estimate First, Then Calculate

Guess and Check

Start by making a quick estimate of the answer before doing the math. Estimating helps you spot mistakes and see if your final answer makes sense. After you estimate, do the calculation for the exact answer. Compare both to catch errors and improve your accuracy!

Examples

  • Rounding numbers in a math problem to check if your answer is close.

  • Estimating the total cost before adding up exact prices.
