Standard 8: Whole Number Computation

In grades K-4, the curriculum should develop whole number computation so that students can:

Model, explain, and develop reasonable proficiency with basic facts and algorithms

Use calculators in appropriate computational situations

Benchmarks

Benchmarks 12C (Habits of Mind: Manipulation and Observation)
Grades 3-5, page 293
Use calculators to determine area and volume from linear dimensions, aggregate amounts of area, volume, weight, time, and cost, and find the difference between two quantities of anything.

Select and use computation techniques appropriate to specific problems and determine whether the results are reasonable

Benchmarks 12B (Habits of Mind: Computation and Estimation)
Grades K-2, page 290
Judge whether measurements and computations of quantities such as length, area, volume, weight, or time are reasonable in a familiar context by comparing them to typical values.
