The problem with this is that the rings that measuring cups and spoons come attached to are usually difficult to work with. You have to struggle to get them to open wide enough, and to keep them open as you add things on or take them off. Hence, I toss the plastic rings and replace them with book rings... much more user friendly!
I couldn't find any yellow ones, but they are available in colors, if you'd like them to match your kitchens. Check out the pretty green book rings:
I also have all measuring equipment kept together in one crate; that way again we're not searching for random tools. As long as they pull out the "measuring crate," they have everything they'll need to measure. A few years ago WalMart had these mini crates for sale in a myriad of colors, a perfect fit:
I load these with dish towels and dish cloths before the first lab of the day and place them in the kitchens; the students are then responsible for refilling them as part of their clean-up at the end of the lab, so that the next class will be set up. One less thing I have to do myself, and prevents later classes from running back and forth to the laundry baskets.
Simple little things like these can make all the difference, don't you think?
