Go to:


Standard 6 

Estimation and Computation Standards

Grades K-4

Estimation (NCTM Standard 5)

The curriculum shall include estimation so students will:

  • Explore estimation strategies; 
  • Recognize when an estimate is appropriate; 
  • Determine the reasonableness of results; 
  • Apply estimation in working with quantities, measurement, computation, and problem solving.

 Whole Number Computation (NCTM Standard 8)

The mathematics curriculum shall develop whole number computation so that students will:

  • Model, explain, and develop reasonable proficiency with basic facts and algorithms; 
  • Use a variety of mental computation and estimation techniques; 
  • Use calculators in appropriate computational situations; 
  • Select and use computation techniques appropriate to specific problems and determine whether the results are reasonable.

Grades 5-8

Computation and Estimation (NCTM Standard 7)

The mathematics curriculum shall develop the concepts underlying computation and estimation in various contexts so that students will:

  • Compute with whole numbers, fractions, decimals, integers, and rational numbers; 
  • Develop, analyze, and explain procedures for computation and techniques for estimation; 
  • Develop, analyze, and explain methods for solving proportions; 
  • Select and use an appropriate method for computing from among mental arithmetic, paper-and-pencil calculator, and computer methods; 
  • Use computation, estimation, and proportions to solve problems; 
  • Use estimation to check the reasonableness of results.

Grades 9-12

Although NCTM Standards do not specifically reference estimation and computation standards for grades 9-12, these skills are necessary components of the mathematics curriculum in grades 9-12. Standards noted above for grades 5-8 should be extended and reinforced throughout the grades 9-12 curriculum.

ADULT BASIC EDUCATION

Estimation (ABE Standard 5)

The curriculum design shall include approaches to teaching estimation which allow the learner to:

  • Explore and develop the concepts underlying a variety of estimation techniques and strategies for whole numbers, fractions, decimals, and percents; 
  • Recognize when an estimate is appropriate and useful in real-life situations and the role estimation plays in adult life; 
  • Apply estimation techniques in working with quantities, measurement, computation, problem solving, and in workplace and test situations; 
  • Use estimation to check the reasonableness of results.
