Abstract

DC60 (20/08/52) Mathematics learning materials. A set of dividing integers by fractions According to invention With characteristics as Rectangular wooden board There is a frame around a rectangular shape. There are horizontal screen lines divided into 2 rows, each row is screened into 3 squares, a total of 6 squares with the same width of each channel and the same length of each channel. To insert the player into a rectangular wooden plate All 6 pieces of the same size by the player are rectangular wooden planks painted on both sides. And can remove the player that is a wooden shape The rectangles are exited from each opening and can be turned over. And a player that is a rectangular wooden plate each One side of the top and bottom rows of different colors. But the other side of each body is painted the same white color to describe and divide integers by fractions. This invention is suitable for teachers and students to Use as learning materials And used to organize mathematics teaching process on division of integers by fractions and to facilitate teachers in choosing to use mathematics materials used in classroom teaching. Studying correctly and appropriately builds students' knowledge and understanding of the proof of theory from concrete to abstract. Is a quality medium according to the principles of mathematics Strong, durable materials that reduce costs and reduce the time required to fabricate multiple times. And convenient to store Strengthen the mind A creative and positive attitude in learning about mathematics for young students. The set of media for dividing an integer by this fraction. It is a math learning medium that teachers use in assembling. Organizing the classroom teaching and learning process It is characterized by a rectangular wooden board with a rectangular frame. The dividing lines are screened into 2 horizontally, in each row the lines are screened into 3 squares, a total of 6 squares with the same width of each channel and the same length of each channel. To insert a player that is a rectangular plank, a total of 6 pieces of the same size, 6 pieces by the players painted on both sides. And the player can be removed from the channel in each channel Reversible And each player on one side of the top and bottom rows do a different color. But on the other side of but Each body was colored the same white all. This invention is suitable for teachers and students to use. As a learning medium And used to organize mathematics teaching process on dividing whole numbers by fractions And facilitate teachers in choosing to use mathematical materials used for organizing Teaching and learning processes in the classroom Build students' knowledge and understanding in the creation of knowledge that proves the theory from concrete to abstract. It is a medium that has quality, mathematically correct, cost reduction and time to create or produce media from poor quality materials And convenient to store Build creativity And good attitude in learning about subjects Mathematics for students.
