TH8892A3 - Mathematics learning materials Volume set of a sphere (Method 4) - Google Patents

Abstract

DC60 (19/12/56) Mathematics Set Volume of a sphere (Practice 4) It is a medium used by teachers in classroom teaching with two pieces of transparent plastic players. The first piece looks like a clear plastic player. Half spherical with a circular clear plastic lid And in the middle of the clear plastic, the circle has a perforated hole in the middle, and the second one looks like a clear plastic joker, a round cone with a circular transparent plastic cover. And in the middle of The circular clear plastic has a perforated hole in the center. Which is a half round transparent plastic player and a transparent plastic player Round cone has the same diameter of the base and height. To describe and express the relationship of Volume of a sphere (Method 4) will take into account the volume of the half-sphere transparent plastic player, which will have Volume is equal to volume, clear plastic player, round cone Which this invention is suitable for use as Mathematics teaching materials in the classroom on the origin of formulas and calculations about the volume of spheres and facilitate teachers in choosing the math materials used in their teaching. In the classroom to properly build knowledge and understanding of the students in the formation of knowledge that is Proof of theory From concrete to abstract Is a medium of quality correct according to academic principles Mathematical The materials are strong, durable, lower costs and the time it takes to fabricate the media multiple times and convenient for storage. Fostering creativity and a positive attitude in learning about subjects Mathematics for students. Mathematics learning materials Volume set of a sphere (Practice 4) It is a medium used by teachers for teaching in class with two pieces of transparent plastic players. The first piece looks like a semicircular clear plastic player with a circular plastic lid. And in the middle of the clear plastic, the circle has a perforated hole in the middle, and the second one looks like a clear plastic play, a round cone With a clear plastic circular lid And in the middle of The circular clear plastic has a perforated hole in the center. Which is a half-circle clear plastic player And a clear plastic player, a round cone with the same diameter and height To describe and express the relationship of The volume of a sphere (practice 3) will take into account the volume of the semicircular clear plastic player, which is equal to the volume of the clear plastic player, the round cone. Which this invention is suitable for use as Mathematics teaching materials in the classroom on the origin of formulas and calculations about the volume of spheres and facilitate teachers in choosing the math materials used in their teaching. In the classroom to properly build knowledge and understanding of the students. Proof of the theory From concrete to abstract Is a medium of quality correct according to academic principles Mathematical The material is strong, durable, reduces costs and the time it takes to create media multiple times and convenient for storage, fostering creativity and a positive attitude in learning about subjects. Mathematics for students.
