掌握代數 I：從基礎到解決問題

This course is great for students who have completed prealgebra and need homework or exam assistance with Algebra I.  Typically, I use the lesson resources provided by the student for instruction.  My teaching tools include a whiteboard to practice problems and improve student engagement.  I demonstrate problem solving strategies by explaining each step. I encourage questions throughout the session and finish the sessions with an overview of what was covered. 

Topics that will be covered include Semester 2 content:
