TH5682C3 - Mathematics learning materials The set of dividing fractions by integers - Google Patents

Abstract

DC60 (20/08/52) Mathematics learning materials, division and integer division, is a medium used by teachers in classroom teaching. With the appearance of a rectangular wooden board There is a frame around a rectangular shape. The channel was divided into 2 horizontal rows by a piece of wooden bar, each row size of width. Of each row of the same width and The length of each row is the same in the space in the bottom row. The lines are screened into 3 compartments to insert the wooden-shaped player. Squares of the same size 3 pieces by the square wooden player, painted on both sides and the square wooden player can be removed. Exit from each channel and turn it over and the player that is Each square shaped piece of wood is made in a different color. The other side of each body is colored the same white color. All numbers to describe and illustrate the division of fractions by integers. This invention is suitable for teachers. And students in using it as a mathematics teaching aids on dividing fractions by integers and facilitating teachers in choosing the correct mathematics materials used in classroom instruction. Build students' knowledge and understanding in the creation of theoretical knowledge. From concrete to abstract Is a quality medium according to the principles of mathematics Materials that are strong, durable, reduce costs and reduce time. The need to fabricate media many times and convenient to store. Foster creativity and positive attitude in It's learning about mathematics for young students. This set of fractions It is a learning tool for mathematics that teachers use in the preparation of Classroom teaching process With the appearance of a rectangular wooden board with a picture frame The rectangle is divided into two horizontal rows by one wooden bar in the bottom row. The lines are screened into 3 squares with the same width of each row and the same length of each row to fit a player that is a square-shaped wooden board. Pieces by the player, paint on both sides And the player can be removed from the channel in each channel and turned over Each player has a different color and each player has a different color. But the other side of each body is colored the same white color to describe and divide fractions by integers. This invention is appropriate. For teachers and students to use as learning materials And used for teaching and learning processes in mathematics on dividing fractions by integers And facilitate teachers in their choice of Math media Used in organizing the teaching and learning process in the classroom Correctly build knowledge and understanding of students in the formation of knowledge. That is a proof of the theory from the concrete to the abstract as a quality medium And convenient to store Build creativity And a good attitude in learning about mathematics for students
