Would you use a benchmark of 1,000 to estimate the number of shoes in your classroom? Explain.
Thank you Ms. Sue for your explanation. It was very helpful. Do you know what benchmark means in this problem I don't understand.Thank You

A benchmark is the mark by which all other numbers are judged.
Your teacher is asking you if 1000 sounds like a realistic number of shoes in your classroom. It helps you to understand benchmarks because they may tell you whether you've done your math correctly. 
no because there are only 18 kids in the classroom
