About this worksheet

What students practice

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

How to use

Use after teaching square-root estimates. Have students work without a calculator, use the supplied square comparisons, and discuss the final reasoning task.

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.

Model Rocket Launch Day: Estimate Board

Use rational bounds to check measurements, compare values, and position markers.

Check the Measurements

Use the given square comparisons. Keep estimates separate from exact values.

1.
A model rocket's measured flight data give a calculated height of √147 meters. Which interval is supported by the table?
Height Estimate Checks
NumberSquare
12.1146.41
12.2148.84
12.3151.29
  • A. 12.0 < √147 < 12.1
  • B. 12.1 < √147 < 12.2
  • C. 12.2 < √147 < 12.3
  • D. 12.3 < √147 < 12.4
2.
A launch sensor's calculated delay is √0.3 second. Use 0.547² = 0.299209 and 0.548² = 0.300304.

Estimate the delay to the nearest hundredth:   second

3.
For a ground test, a tracking distance is √n meters. It must be greater than 8.2 meters and less than 8.5 meters. Select every value of n that meets this requirement. Use 8.2² = 67.24 and 8.5² = 72.25.
