Estimating Length
Estimating means making a good guess without measuring exactly. Benchmark lengths: 1 cm โ width of your little fingernail; 1 m โ your arm span; 10 m โ length of a bus. Estimation skills: look at the object, compare to a benchmark, make your estimate, then measure to check. Good estimates are close to the actual measurement.
