This article discusses practical ideas teachers particularly senior high school teachers could use in the classroom activities in line with the most recent teaching approach based on Competency-Based Curriculum (CBC). The discussion begins with CBC s background characteristics and practical formats for classroom activities. The paper offers teachers with handy experience of applying CBC for English teaching at senior high schools. It is anticipated that later on EFL teachers extend their own activities in their class to craft the English teaching at senior high schools to be more meaningful and fun.
