Values: Active Participation, Cooperation III. Procedure: Teacher Activity A. Preliminary Activities 1. Prayer: Let us stand and pray 2. Greeting: Good Morning Children You may now take your sit 3. Checking of Attendance: Is there any absent today? Very good! Students Activity In the name of Father and the Son and the Holy Spirit Amen! Good Morning Ma’am Nana Thank you ma’am Nana None Ma’am Nana 4. Classroom Management: Can you please sit properly so we can start our lesson today! B. Preparatory Activities: 1. Drill: Guess who am I? My name is given in the box below. Oops! Spelling of my name is jumbled up. Try to identify it from the clues given below and write it in the blank space. _________(1) I am a solid with two congruent circular bases that are parallel. ________(2) I am a prism whose all faces are square. ________ (3) Looks like marbles but have no vertex. ________ (4) I am a solid whose base is polygonal and other faces are triangles. - cylinder Cube Sphere Pyramid CLINYDER 2. Review Yesterday we differentiate the plane figures to the solid figures. (call a student who want to answer the given figures ) Yes Ma’am! Circle the 3D shapes (Solid figure) and Check the 2D shapes (Plane figure). Pupils will do the boardwork C. Developmental Activities: 1. Activity I have here a big box inside of this box has different shape all you have to do is to pick one shape in this box and tell to everyone what kind of shape did you pick. Yes Ma’am Is that clear? So who wants to pick first in my big box? Anyone? Cube . sphere cone sphere cylinder cube cone cylinder 2. Analysis Can you guess what is our lesson for today? Very good! Solid figure Ma’am So how we will describe the solid figure? I have here a box. (Show them a big box.) What is the shape of the bottom part of a box? Is it the same with the shape of the top part? Rectangle yes! What is the shape of the right side of the box? Does it have with the same shape with the one on the left side? Square Yes! Do the back and front sides of the box have the same shape? Yes! So how many faces does the box have? 6 faces ma’am Very good! How many edges that the box have? 12 edges Ma’am Very good! How about vertices? How many vertices that the box have? 8 vertices Very good! Thus the box has three- dimensional object? Yes! Why yes is your answer? Because it has length width and height. Very good! So how we will describe a solid figure? Very good! Solid figure has threedimensional object if they have length, width and height. So class this means that This box is a solid figure called rectangular prism, because of its rectangular base, has 6 faces, 8 vertices and 12 edges. That you said a while ago. So what is prism? Who wants to read? (one student will read the definition of a prism) A Prism is a polyhedron that has two congruent parallel faces called base. When we say polyhedron this means a solid figure whose side are polygon. Each side is called faces. Two faces that intersect in a line segment is called an edge. And two edges that intersect in a point is called a vertex. (The teacher pointed out where’s the faces edges A Prism is a polyhedron that has two congruent parallel faces called base. and vertex in a box) When we say two congruent parallel faces called base, meaning to say two same bases was aligned in bout side. Can you follow? Yes Ma’am I have here some prism that was named according to the shape of its base. name Shape of the base Number definition example of lateral faces Triangular triangle 3 Composed prism of two triangular bases and three rectangular lateral faces. Rectangular rectangle 4 Composed prism of two rectangular bases and four rectangular lateral faces cube Square 4 A cube is a prism with a square base. all its faces are square Pentagonal Pentagonal 5 Has two Prism pentagonal bases and five rectangular lateral faces. The lateral faces are the faces that join the base of a solid figure. Always remember that each faces is a polygon. Is that clear? I have here another solid figure can you tell me what is the name of this solid figure? Yes ma’am This are the clues how will you observe a figure 1. The sides are all polygon 2. The figure is a prism 3. Its base are hexagons What would be the answer? The figure is a hexagonal Prism 8 faces 18 edges 12 vertices How many faces? How many edges? How many vertices? Another prism is pyramid which is also named according to the shape of its base. Please read the definition of pyramid (one student will read the definition of the pyramid) A pyramid is a polyhedron whose base is a polygon and the lateral faces are triangles. Meaning to say if the prism has 2 equal bases the pyramid has only one base but the lateral faces are triangle. Is that clear? Yes Ma’am Here are some example of pyramids that was name according to the shape of its base. name Triangular pyramid Rectangular pyramid Square pyramid Shape of the base triangle Number of lateral faces 3 rectangle 4 square 4 example Is that clear? Yes ma’am Can you name the figure? Count the number of faces, edges and vertices. This are the clues 1. The lateral faces are all triangles 2. The figure is a pyramid 3. The base is a square What would be the answer? Very good! the figure is a square pyramid It has 4 faces, 8 edges and 5 vertices. Other solid figures have curved surfaces name definition Example cylinder Has two circular bases that are congruent and parallel cone Has one circular base sphere Is a curved surface of points that are all the same distance from the center 3 .Abstraction What is solid figure? Very good! Can you give me some example of solid figure? Okay very good! 4. .Application (The class will group into 4 group) What we should do when doing an activity? Solid figure has threedimensional object if they have length, width and height. Hexagonal prism Rectangular prism Triangular prism Square pyramid Cone Sphere Cylinder Etc. 1. Be quite 2. And participate in a group activity. Very good children. A. Activity group 1 Identify the picture what kind of solid figure it is. Cube 1.____________ Cylinder 2. ______________ Rectangular prism 3.____________ Sphere 4.______________ B. Activity group 2 Match the column A (2D shape) to column B (3D shape) ● • C. Activity group 3 Identify how many edges, faces and vertex did the solid figure below.
