I finally organized my tot school bins! I have five bins total. Two of them are put away because one contains seasonal items and the other contains activities for when A is older. Here is how I organized the three that are always within reach:
I organized all of the little manipulatives into baggies and placed them into a bin I labeled, "materials"
I used another bin to hold my containers.
The final bin was used for my ready-made activities.
Here is my lovely shelf that hold all of our tot school bins as well as our art/craft materials. It's in the garage and I love having these things organized and at my fingertips!
The bins I use can be found here.
