With this objective in mind, this new series offers the following salient features: 1. An authentic and straightforward development of every lesson 2. Prerequisite Knowledge-a drill that prepares every learner for a new lesson 3. Main Idea-an idea or theorem that needs emphasis 4. Conceptual Insight - a marginal note for the learners about a certain concept or skill, or a word of caution for common mistakes made by most learners 5. Matched Problem-a quick follow-up exercise with parallel concept or skill as the example right before it 6. A set of well-chosen exercises at the end of every section and chapter to reinforce the concepts and skills developed in the section and chapter 7. A collection of challenging or Olympiad-type problems to strengthen the mathematical ingenuity of the learners 8. Performance Task or Mini-Research Project-a learning activity that enhances the knowledge, understanding, and proficiency of every learner With the competencies and standards prescribed in the K-12 Math Curriculum as its minimum assumption, the book also includes topics that go beyond the curriculum. The inclusion of these topics widens the mathematical horizon of the learners. We fervently hope that this new series of OWOM will provide you with the skills necessary for a mathematically-sound 21st-century learner.
