Units of Measure Chart for Math Notebooks
I use this in our interactive notebooks so students have a reference for these units of measure.
I have also included my handy tips on how to remember the approximate measurements for Customary and Metric weight. While not exact, the bread and peanut comparison, offer students an idea of approximate weight with items they are familiar with. (I tried to come up with a peanut-free example, but I couldn't find something that was consistently a gram that made sense.)
You can actually locate loaves of bread that weigh a pound if you hunt around enough. I found a loaf at a dollar store that was 1lb but with 18 slices. (Extension Idea: Let your high students determine exactly how many oz each slice would be if the weight was equally divided between the 18 slices. Remember they will need to convert the lb to oz before dividing by 18.)
