About this worksheet

What students practice

  • Students use rational bounds to estimate and compare irrational numbers.
  • Students place irrational numbers approximately on a number line.
  • Students estimate expressions involving square roots and π².

How to use

Use after introducing square-root estimation. Have students work without a calculator, show supporting comparisons, and discuss the final error analysis.

Curriculum

Common Core standard covered

8.NS.A.2

Estimate irrational numbers with rational ones to compare them, place them on a number line, and estimate expressions like pi squared.

Space Camp: Mission Estimate Controls

Use rational estimates to check the mission simulator's numbers.

Calibrate the Controls

The space-camp simulator uses irrational values in its models. Use squares and the supplied bounds to make rational estimates.

1.
A calibration value is √31. The table places it between 5.5 and 5.6. Which number should you square next to split this interval into two equal parts?

  • A. 5.05
  • B. 5.55
  • C. 5.65
  • D. 5.15
2.
A simulated signal delay is √0.6 second. Use 0.77² = 0.5929 and 0.78² = 0.6084.

Estimate the delay to the nearest tenth:   second

3.
The control screen rounds each calibration value to the nearest whole number. Sort the exact values by their rounded results.
