Density is a wonderful exercise in physical science and applied math.
The students should repeat this over and over in various forms year after year.
A big part of applied math is tracking the units. The answer sheets are carefully constructed to include all units and the teacher can use the answer sheets for the class without any preparation or even knowledge.
This download includes an exercise, a carefully constructed answer sheet and the four thumbnails.
This could be handed out to kids as young as 6th grade. But you are a teacher and know your job. Watch them and if they have trouble, be prepared to transition into a group lecture. The answer sheet and the teacher directions will guide you.
