Checking Your Work and Estimating

Be Your Own Math Detective

Always double-check your answers, especially in longer problems. Estimating before you solve can help you catch mistakes if your answer is way off from your estimate.

  • Review each step for errors
  • Estimate the answer before solving
  • Compare your result with your estimate

This habit helps you catch mistakes and become a more confident problem solver!

Examples

  • Estimate the answer to \( 49 \times 2 \) as about 100, then check your actual calculation.

  • After solving an equation, plug your answer back in to ensure it works.
