Use appropriate ratios and proportions, including constant rates, when needed to make calculations for solving real-world problems.
Learning Goal 2
Find answers to real-world problems by substituting numerical values in simple algebraic formulas and check the answer by reviewing the steps of the calculation and by judging whether the answer is reasonable.
Learning Goal 3
Make up and write out simple algorithms for solving real-world problems that take several steps.
Learning Goal 4
Use computer spreadsheet, graphing, and database programs to assist in quantitative analysis of real-world objects and events.
Learning Goal 5
Compare data for two groups by representing their averages and spreads graphically.
Learning Goal 6
When describing and comparing very small and very large quantities, express them using powers-of-ten notation.
Learning Goal 7
Trace the source of any large disparity between an estimate and the calculated answer.
Learning Goal 9
Consider the possible effects of measurement errors on calculations.
