# G9 Math

#### Description

Course description

This is a course based on DepEd’s Curriculum Guides for grade 9 students.

It is designed for use by in any public or private school, in a blended learning environment.

Learning can be instructor led, but delivered asymmetrically.

It can also be used by students in private schools which have not yet reopened.

Self-paced learners are encouraged to enroll in this course to develop self motivation, critical thinking, inquisitiveness, and a learning-for-life attitude.
