MONDAY TUESDAY WEDNESDAY THURSDAY FRIDAY
I.OBJECTIVES Objectives must be met over the week and connected to the curriculum standards. To meet the objectives, necessary procedures must be
followed and if needed, additional lessons, exercises and remedial activities may be done for developing content knowledge and
competencies. These are assessed using Formative Assessment strategies. Valuing objectives support the learning of content and
competencies and enable to find significance and joy in learning the lessons. Weekly objectives shall be derived from the curriculum guides.
A. Content Standards Demonstrate an understanding of the digestive system and its interaction with the circulatory, respiratory and
excretory system in providing the body with nutrients for energy.
B. Performance Standards Present an analysis of the data gathered on diseases resulting from nutrient deficiency.
C. Learning Compare mitosis and Compare mitosis and Compare mitosis and meiosis, Compare mitosis and

II.CONTENT Content is what the lesson is all about. It pertains to the subject matter that the teacher aims to teach. In the CG, the
content can be tackled in a week or two.
Heredity: Inheritance and Heredity: Inheritance and Heredity: Inheritance and Stages of meiosis
Variation of Traits Variation of Traits; The Variation of Traits; The Mitosis

III.LEARNING RESOURCES List the materials to be used in different days. Varied sources of materials sustain children’s interest in the lesson and in
learning. Ensure that there is a mix of concrete and manipulative materials as well as paper- based materials. Hands- on
learning promotes concept development.

IV.PROCEDURES These steps should be done across the week. Spread out the activities appropriately so that students will learn well.
Always be guided by demonstration of learning by the students which you can infer from formative assessment
activities. Sustain learning systematically by providing students with multiple ways to learn new things, practice their
learning processes, and draw conclusions about what they learned in relation to their life experiences and previous
knowledge, indicate the time allotment for each step.
