Simple diagrams to explain 50 classroom activities

Job ID: 35898171

Budget: $250 – $750 USD

I am creating a manual for English teachers. There are 50 classroom activities which I explain how to do. Each classroom activity has a short written instruction and a simple diagram. I have made all the diagrams myself, but I want a professional designer to improve them (or else make completely new illustrations/diagrams).
I have attached the first 5 activities as an example.
