As a tutor and a teacher I have used the one on one approach and subject based tutoring. I based each lesson and format on the child's specific needs and their IEP's. When I was a tutor, the child would come with the work they needed extra help with and what they were struggling after school. While I was a teacher, I worked in a specialized setting that was focused on each child's specific needs, development and adapted everything to what they needed. I also worked in an ABA (Adapted Behavior Analysis), with children who have Autism with a trial based system where we would have classroom lessons with all the students and a designated time where they will have tasks based off their IEP's and needs.
I would usually base my lessons off of certain weekly themes as well as weekly color, letter and shape recognition during the classes circle time. I try to make my students feel comfortable and excited to do work, I go at the pace that is needed and believe and use a reinforcement strategy. I find that, especially with younger learners, reinforcers and timed breaks to help and maintain their attention throughout the lesson.
