Match Your Lids With Your Containers
If you don’t want to separate your lids from your containers, match them appropriately. Stack your containers, and then shove the lids into the top container. Or, you can place the lids underneath the stack of containers.
Another method involves slipping lids in between towers of tupperware. If you can mentally keep track of which lid goes where this method can work for you. Pick a method that you don’t need to memorize, or else you’ll forget within minutes.
