Abstract

DC60 (25/05/56) Mathematics learning materials. A series of determination of the surface area of a sphere using a cylinder and a sphere. The surface of a sphere using a cylinder and a sphere. It is a medium that teachers use in teaching and learning in the classroom. Which looks like a round wooden player at the height It is directly equal to the length of one piece of diameter. The center of the round player is made of grooves around it to show the centering of the round player. And the top area of the round wooden player There are 1 small wooden stick and a half round wooden player. The cross-section is a circle whose diameter is equal to the height of the round wooden player and the top area. Of half round wooden players There is 1 small wooden stick and a small cotton rope string. The length is equal to its length when wrapped in a half round wooden player and wrapped around a circular cross-section of the player. Half spherical fit perfectly Which this invention is suitable for use as a medium for teaching mathematics The class on the formula for determining the surface area of a sphere and the relation of its origins, finding the surface area of a sphere, and facilitating the teacher to choose the mathematics materials used in their teaching. Classes accurately and appropriately build students' cognition to generate theoretical knowledge. From concrete to abstract Is a quality medium according to the principles of mathematics The materials are strong, durable, lower costs and the time it takes to fabricate the media multiple times and convenient for storage. It can foster creativity and a positive attitude in learning about mathematics for students. -------------------------------------------------- -------- Mathematics learning materials set Finding the surface area of a sphere using a sphere and a half sphere It is a medium that teachers use in teaching in class with a round wooden player with all the surfaces Smooth surface to be suitable for stringing Which has the height of the round wooden player And length of the line Through the center of the player, a spherical stick of equal length And have a length equal to the length of the diameter Of the player's half-round wooden player 1 piece directly in the center of the player's round wooden player, with all the skin's characteristics A smooth surface to be suitable for stringing, grooves are made around it to show the midline of the player. Spherical with all surfaces being a smooth surface to be suitable for stringing. And the area on top of Round wooden player There are 1 small wooden stick and a half round wooden player with all surfaces. Smooth surface to be suitable for winding rope with a long diameter circular cross-section. Equal to the height of the round club player and the upper area of the half round player's top area. The entire surface is smooth to be suitable for stringing. There is 1 small wooden stick and a small cotton rope string equal to the length of the half round stick. And wrapped around the circular cross-section of the wooden player half-round perfectly Which this invention has It is suitable for use as a mathematics teaching material in the classroom on the formula for finding the surface area of Spheres and their derivation of the surface area formula. And facilitate teachers In order to select the correct mathematics materials used in classroom teaching and to build students' knowledge and understanding in the formation of theoretical knowledge. From concrete to abstraction is a quality medium according to the principles of mathematics. The material is strong, durable, reduces costs and the time it takes to fabricate materials multiple times and is convenient for storage, fostering creativity and a positive attitude in mathematics learning for young students.
