Teaching and Learning Approach
Students will practice hands-on exercises to learn efficient ten-key touch method techniques and skills needed to
make quick and accurate calculations. Students develop workplace competence by solving common business
and personal math problems and improve their basic math skills through a series of problems, self-assessments,
and practical tests. Strong calculator skills support the student’s overall objective by enhancing productivity and
timely completion of assigned tasks in the workplace. Following instructions and using software functions
proficiently, students develop a range of valuable skills essential for the office environment.Learning Resources
