Review Yesterday we discuss the adding integers. Right? So I guess all of you can answer this equation Yes Ma’am! (call a student who want to answer the equation) Add the following Integers. 1. (-8) + (-7) = 2. (+11) + (+23) = 3. (-43) + (+17) = 4. (+59) + (+73) = 5. (+102) + (-102) = -15 +34 or 34 -26 +14 or 14 0 C. Developmental Activities: 1. Motivation 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. Is that clear? So who wants to pick first in my big box? Anyone? Cube . sphere cone sphere cylinder cube cone cylinder 2. Discussion Can you guess what is our lesson for the day? Very good! So how we will describe the solid figure? Solid figure Ma’am 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 and vertex in a box) A Prism is a polyhedron that has two congruent parallel faces called base. 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? None 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 pentagon What would be the answer? Very good! Other solid figures have curved surfaces name definition Example the figure is a pentagonal pyramid It has 6 faces, 10 edges and 6 vertices. cylinder cone sphere Has two circular bases that are congruent and parallel Has one circular base Is a curved surface of points that are all the same distance from the center 3 .Generalization: What is solid figure? Very good! Can you give me some example of solid figure? Solid figure has threedimensional object if they have length, width and height. Hexagonal prism Rectangular prism Triangular prism Square pyramid Cone Sphere Cylinder Etc. Okay very good! 4. .Application: (The class will group into 5 group) What we should do when doing an activity? Very good children. 1. Be quite 2. And participate in a group activity. Activity group 1 Identify the picture what kind of solid figure it is. Cube 1.____________ Cylinder 2. ______________ Rectangular prism 3.____________ Sphere 4.______________ cone 5.______________ Activity group 2 Match the column A (2D shape) to column B (3D shape) Activity group 3 Identify how many edges, faces and vertex did the solid figure below. HEXAGONAL PRISM EDGES:__________________ FACES:__________________ 18 edges 8 faces 12 vertex VERTEX:_________________ PENTAGONAL TRIANGLE EDGES:__________________ FACES:__________________ 10 edges 6 faces 6 vertex VERTEX:_________________ Activity group 4 Write check ( / ) if the picture is solid figure and ( x ) if is not. 1.__________ 2. _____________ 3. ____________ 4. _____________ 5._________ 1. 2. 3. 4. 5.
