Metric Conversion

How and Why

Students who sit on the left complete the odd numbered problems. Students sitting on the right complete the even numbered problems. Compute the answer (how) and explain ‘why’ that is your answer. Skip 5 lines between each problem. This allows room for your answer and any corrections later. REMEMBER: I DON’T WANT AN EXPLANATION OF HOW YOU GOT YOUR ANSWER, BUT WHY THE ANSWER WOULD BE THAT NUMBER.
