Which statement describes the TEKS expectation for measuring length using standard units?

Which statement describes the TEKS expectation for measuring length using standard units?

• A. Find the length of objects using concrete models for standard units of length
• B. Estimate length using mental math without tools
• C. Describe length verbally without measurement
• D. Compare lengths using nonstandard units only

Answer: (A)

Measuring length with standard units uses concrete tools to determine exact length in units like inches or centimeters. This means finding how long something is by actually measuring with a ruler, measuring tape, or other standard tools, not just guessing. The statement fits this skill because it describes finding the length of objects by using concrete models that represent standard length units. Estimating without tools, describing length without measurement, or comparing lengths only with nonstandard units don’t meet the expectation of measuring with standard units.
