Objectives/Agenda Objective: 1) Safety and 2) 1 D motion and Error analysis Agenda: Safety Quiz and Contract Review IB information about 1.1, 1.2, and 2.1 (1D) Review list of specific concepts and skills for Unit 1 Self ratings to determine which to clarify or practice Practice the needed concepts and skills for Unit 1 Assignment: Safety Contract Signed by Student and Parent/Guardian. Prepare for Unit 1 Mastery Quizzes on Friday

Skills and Concepts: Where are you? Refer to the IB Objectives List Assess where you are with each objective: 1 – Got it, know about it, know how to do problems, could write my own problems 2 – Pretty sure I remember, know where to find formula on data packet, could use a refresher 3 – Need to review, never did quite get that, don’t remember 4 – Greek, never did it,

Review as needed Teacher reteach mini- lesson Classmate clarifications Teacher created problems to solve (pop quiz) to verify proficiency (boost grade) Student created problems to cross challenge Selection of textbook problems for practice Revisit last year’s materials Record summary statements or recommendations for these kinds of problems Create a concept map Other ideas?
