Abstract

DC60 Mathematics Set Adding and subtracting fractions when the denominator is the same. A teacher Used in classroom teaching With the appearance of a rectangular wooden board with a frame around a rectangular shape There are screen lines divided into lines. Each channel has the same width, each channel is the same width and the length of each channel is the same length. To put a player that is a wooden plate A total of 10 rectangular shapes by the player is a rectangular wooden plank. Paint on both sides The rectangular wooden player can be removed from the slots in each row and turned over and the rectangular wooden player can be removed from the slots in each row. Every player plays at Is a rectangular plank, one side made of the same color, and the other side of every player that is a wooden plank. Is a rectangle made of white color, the same in every row, the size of every player, the player is a wooden plank A rectangle with the same size To describe the addition and subtraction of fractions when the denominator is equal, to show the addition and subtraction of fractions when the denominator is equal. This invention has It is suitable for teachers and students to use as teaching materials for mathematics on addition and subtraction of fractions when the denominator is equal, and facilitates teachers in choosing to use mathematics media used in teaching and learning processes. In the classroom, correctly and appropriately build knowledge and comprehension of the students in the formation of theoretical knowledge. From concrete to abstraction is a quality medium according to the principles of mathematics. The material is durable, cost-effective, and the time it takes for the media to be fabricated multiple times and convenient for storage. Fostering creativity and a positive attitude in mathematics learning for young students have shown this series of addition and subtraction when the denominator is equal. Is a medium for learning mathematics that teachers Used in the assembly of the classroom teaching and learning process. With the appearance of a wooden board rectangle There is a rectangular frame on the cloth floor. There are screen lines divided, each channel has the width of Each channel is the same width And the length of each channel is the same length To put a player on a wooden plate that It is a rectangle in total of 10 pieces, with the players painted on both sides And can remove the player From the slots in each row Then turn it over And all players on one side do the same color and the other side of all The color stabilizer is the same white every row. All players are the same size. In order to express the addition And subtracting fractions when the denominator is equal. This invention is suitable for teachers and students to use. It is a learning tool and used to organize mathematics teaching process on addition and subtraction. Fractions when the denominator is equal and it facilitates teachers in choosing mathematical materials used Organizing the classroom teaching and learning process To properly build the knowledge and understanding of Students in the creation of knowledge that proves the theory From concrete to abstract It is a medium of quality, mathematically correct, cost reduction and time for creating or producing media from Poor quality material And convenient to store Build creativity And a good attitude in Learn about maths for young students.
