Number Detectives

In math, I'm trying to help my students with understanding number concepts.  They understand whole numbers, but struggle with negative numbers, fractions, and decimals.  I found an activity online and "tweeked" it. 

I have been using this "Number Detectives" as a warm-up activity each day.  I give each set of partners a sheet with a number already written in.  For example, I will write in "0.41" or "-0.41" or "34.3%".   Then, with a partner, the students have to find different ways to prove that number.  It's been a great way for them to visualize the number, as well as prove what the number means.
