Here are just a few more organizational ideas I stole from my ECS 100 Field Placement in Pre-K.
Sorting crayons in jars by colour is a great way to enforce the learning of colours and categorization. It also makes it easier to find the colour you want, rather than sifting through a box full of all colours mixed together (it is also my website banner picture, because it is organized AND colourful!)
All of these tubs have pictures of their contents and written labels (which allows the words for objects to be more easily recognized by students). This allows you to choose the tub you need in seconds, rather than hunting for a glue stick. The tubs labelled “STOP” are for the teacher’s use only.
