ABecause measuring is fun and they want to do it twice
BBecause cutting a piece too short cannot be fixed — you have to start over with new material, so double-checking the measurement prevents waste
CBecause rulers are unreliable and need two readings to be accurate
DBecause cutting twice is dangerous
Once you cut a piece of material too short, you cannot add the missing length back. You have to throw away the piece and cut a new one, wasting both material and time. Measuring twice — verifying your measurement before cutting — catches errors when they are still free to fix.
Question 2 True / False
When using a ruler, you should typically start measuring from the very edge of the ruler.
TTrue
FFalse
Answer: False
Many rulers have a small gap between the edge and the zero mark. If you measure from the edge instead of from zero, every measurement will be slightly too long. Always find where the zero mark is on your ruler and start from there. Some experienced builders start from the 1-inch mark and subtract 1 from their reading to avoid the end of the ruler entirely.
Question 3 Short Answer
Why is it important to mark your measurement on the material before cutting?
Think about your answer, then reveal below.
Model answer: A mark gives you a visible line to follow while cutting, which is much more accurate than trying to hold a ruler against the material while cutting at the same time. Without a clear mark, the cut is likely to wander off the intended line.
Marking separates the measurement step from the cutting step, which lets you focus on each one individually. Trying to measure and cut simultaneously requires you to hold the ruler, hold the material, and operate the cutting tool all at once — which is both inaccurate and unsafe.
