Frequently asked questions
How do you compare two lengths fairly?
Line up the starting ends first. The dashed start line on the worksheets does that job, so kids only need to look at where each object ends.
Why measure with paper clips before a ruler?
Laying the same unit end to end with no gaps or overlaps is exactly what the marks on a ruler do. Kids who have done it with clips understand what the numbers mean.
