LESSON PLAN IN MATHEMATICS

Learning Area Mathematics 7 Quarter III

Date MARCH 31, 2023
CONTENT Adjacent angle and linear pair
CONTENT STANDARD The learner demonstrates understanding of the key concepts of
geometry of shapes and sizes, and geometric relationships.
PERFORMANCE STANDARD The learner is able to create models of plane figures and
formulate and solve accurately authentic problems involving
sides and angles of a polygon.
I. LEARNING COMPETENCY/ Derives relationships of geometric figures using measurements
CODE and by inductive reasoning; supplementary angles,
complementary angles, congruent angles, vertical angles,
adjacent angles, linear pairs, perpendicular lines, and parallel
lines. M7GE-IIIb-1
OBJECTIVE/S Derive relationships of geometric figures using measurements
and by inductive reasoning; adjacent angles and linear pair.
II. LEARNING TASKS A. Subject Matter: Derive relationships of geometric figures
using measurements and by inductive reasoning; adjacent
angles and linear pair.
B. Concept:
Angle is the result of the union of two rays with a common
endpoint. It is measured by means of an instrument, the
protractor, which gives a measure in terms of degrees (°).
Adjacent angles are two angles with a common vertex, a
common side and no common interior points.
Two angles form a linear pair when they are adjacent and
supplementary.
C. Reference: Math 7 Learners Material pages 203 – 204
D. Materials: Protractor, Led TV, PowerPoint presentations,
Laptop, Bondpaper, Protactor and Pen.
