Record the instrument type, scale divisions, calibration status, number of trials, and estimated uncertainty with every measurement.
When you explain this to someone in fifth grade, say that whenever you measure something you should write down what tool you used, how fine the tool can read, whether the tool was checked to be correct, how many times you measured the same thing, and how unsure you might be about the number you got. Think of it like taking a picture of your measurement so someone else can understand how you got that answer: the tool is the camera, the scale divisions are how sharp the picture is, calibration is making sure the camera is working, the number of trials is taking several pictures, and the estimated uncertainty is saying how blurry the picture might be. Writing all those things down next to the result helps others trust your data and lets you compare measurements later.
A common mistake is forgetting to note calibration, which can make measurements look accurate when they are not; always write down the last calibration date or status so people know if the tool was verified. Another error is reporting only a single trial, which hides variability; repeat measurements and list how many you did so readers can see consistency. People also often skip estimating uncertainty and just give a single number, so include a clear uncertainty value or range to show how precise the measurement really is.
