Bottle caps make a great, inexpensive preschool manipulative. If you’re anything like us, it doesn’t take long to accumulate a nice, varied collection of bottle caps. I just toss them into a little basket in the dishwasher as we empty various containers. Then, they’re clean and ready to become sorters and counters and whatever else we can think of.
The caps can be sorted by size, color, variations in shape (big circles or little circles, tall caps or short caps) or whatever other way your preschooler can think of to sort them. They can be stacked or nested, dropped into larger containers for fine motor skills practice (or just to make nice noises!). They can be counted.
What else could you do with a bunch of bottle caps?
