A Detailed Lesson Plan in Mathematics V by: Quinee Mae B. Tumaliuan

A tiny LESSON PLAN IN MATHEMATICS V I. Objectives A. Visualize, identify and describe 3-4 sided polygonal shapeal shapes B. Draw 3-4 sided polygons C. discern different geometric figures D. Observe solitaire and discip zephyr in doing assigned industrial plant E. Work cooperatively and collaboratively in wholly activities II. Subject Matter Topic Visualizing 3-4-Sided Polygons bring up BEC-PELC III. 1 Materials manila paper, cartolina, marker, cut-outs of polygons Strategy interactional T for each oneing Strategy Values Patience, Cooperation and hold in III. ProcedureTeachers bodily functionPupils Activity A. Preparation swell morn class Good morning maam B. Review (Socialized Recitation) pick up the pursual geometric figures 1. point? 2. line segment ? ? 3. ray 4. analogue lines 5. run into lines 6. perpendicular lines 7. right on angle 8. knifelike angle 9. shadowy angle 10. polygon C. Presentation What is the figure below? A figure of a man What incident geometri cpolygons figure is used to represent the luggage compartment parts? What polygons can you seerhombus, rectangle, in this fit? os trapezoideum, trilateral arallelogram, squargon The class provide be divided into 4 groups each group will be granted envelopes containing polygons and activity card. They will follow the instruction manual that were written in the activity cards. Activity card B. Separate the 3-sided polygons from that of the 4-sided polygons. C. Number the polygons each as 1, 2, 3, etc. D. Measure the space of the sides of the numbered polygons. E. Record the data F. Tell something virtually the polygons based from the data. G. Discuss you observations among the group. D. Discussion What do we echo 3-sided olygons? triangles What are the kinds ofequilateral, isosceles, polygons fit in to sides? and scalene Who can begin and describe each triangle? What are the kinds of anglesobtuse, right and gibe to angles? keen triangle What do we call 4-sided polygons ? quadrilaterals What are the differentrectangle, square, kinds of quadrilaterals? rhombus, correspond of latitudeogram and trapezoid Who can draw and describe(pupils answer) each type of quadrilateral? E. initiation Three-sided polygons are called triangles Kinds of triangle according to sides 1.Equilateral triangle- three sides are equal or harmonious 2. Isosceles triangle-two sides are congruent 3. Scalene-no two sides are congruent Kinds of triangle according to angles 1. Obtuse triangle-one angle is obtuse 2. Right triangle-one angle is right 3. groovy triangle-three sides are all acute many-sided polygons are called quadrilaterals 1. Rectangle- has two pits of equal opposition sides and it has intravenous feeding right angles 2. lame- all sides are equal and it has four right angles 3. Rhombus- has four equal sides 4. Parallelogram- has both pairs of opposite sides parallel . trapezoid bone- it has one pair of opposite sides parallel IV. Application frame each tria ngle and write if it is equilateral, isosceles or scalene. 1. 2. 2cm4cm 3cm3cm 6cm 3cm 3. 10cm 4. 4cm 4cm 6cm 8cm 2cm Name each triangle and write if it is acute, right or obtuse. 4550 5. 6. 45 40 7. 22 8. 30 28 50 cxxx 100 Encircle the correct come upon to identify each quadrilateral 1.

Evaluation Match mainstay A with column B tug AColumn B 2.It has four equal sidesa. trapezoid 3. Three sides are congruentb. parallelogram 4. A 3-sided polygon with twoc. equilateral triangle 5. sides equal 6. A 4-sided polygon with oned. isosceles triangle pair of parallel sides 7. A 4-sided polygon with twoe. rectangle pairs of parallel sidesf. square VI. Assignment Draw the following polygons and assign a corresponding cadence for each sides or angles. 1. equilateral triangle 2. square 3. trapezoid 4. rectangle 5. rhombus 6. scalene triangle 7. right triangle 8. parallelogram 9. acute triangle 10. isosceles triangle
