Flashcards

Nonstandard unit: An everyday object used to measure length, like a paper clip, cube, or crayon
Length: How long an object is from one end to the other
How do you measure with nonstandard units?: Place units end to end with no gaps along the object and count how many fit
Why must units be the same size?: So your count is accurate and fair
If a book is 9 paper clips long, what does that mean?: Nine paper clips placed end to end equal the length of the book
What happens if you use smaller units to measure something?: You will need more units to measure the same length
What happens if you use larger units to measure something?: You will need fewer units to measure the same length
Estimate: A careful guess about how long something is before measuring
What is a gap in measurement?: An empty space between units that makes the measurement inaccurate
Name 3 nonstandard units you could use to measure a book: Paper clips, cubes, crayons (or other consistent small objects)
What does it mean if two students measure the same object and get different numbers?: They probably used different sized units
Standard vs. nonstandard units: Standard units (inches, cm) are the same everywhere; nonstandard units (paper clips, cubes) can vary in size
