Look at all that little stuff!
Whenever I’m sorting I start out with what is visually most accessible. That just means I grab the largest, most plentiful pieces first.
That can leave an intimidating pile of tiny elements at the bottom of your sort bucket. The first thing I do is fill the bucket again with unsorted Lego and start over. If you do this a couple times, sorting the mass of littles at the bottom gets easier.
Then, when you’ve got a good pile of smaller pieces, you can use a similar technique to sort. For this assortment, I picked out “dots,” as we call them, or single-stud round plates. Depending on how you’ve decided to break them out, you can choose two colors and use both hands to pluck them from the pile. We haven’t yet broken out all the colors, so I use palettes like earth tones, translucent, reds, and other. 
I hope this helps.
God bless and thank you for reading,
