TH5719C3 - Mathematics learning materials A set of multiplication of fractions by integers - Google Patents

Abstract

DC60 (20/08/52) Mathematics learning materials, multiplication and integer multiplication series 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. There is a separation of screen lines, but Each channel has the same width of each channel. And the length of each slot is the same length to put a player that is a four-piece rectangular wooden board, the player is a rectangular wooden plank, painted on both sides and can remove the player that is the wooden plank. The shape is rectangular, leaving the opening in each compartment and can be turned over. And a player that is a rectangular wooden plate All bodies one side is painted the same color and the other side of each one is white. The same on all channels The size of all players is the same size. To illustrate the multiplication of fractions by integers. It also facilitates teachers in selecting correct and appropriate mathematical materials used in classroom teaching, building students' knowledge and understanding in the formation of theoretical knowledge. From what is Concrete to abstract Is a quality medium according to the principles of mathematics The material is strong, durable, reduces costs and reduces the time required to fabricate the media multiple times. Convenient for storage. Build creativity And a good attitude in learning about mathematics for students This set of mediums to multiply fractions by integers. It is a math learning medium that teachers use in assembling. Organizing the classroom teaching process It is characterized by a rectangular wooden board with a rectangular frame. There are screen lines divided, each channel has the same width of each channel. And the length of each channel is the same length To insert a player that is a four-piece rectangular plank with the player painted on both sides. And the players can be removed from the slots in each channel and turned over and all players one side is painted the same color and the other side of all players are colored the same white. All players are the same size. To display the multiplication of fractions by integers. This invention is suitable for teachers and students for use as learning and business materials. Organize the mathematical teaching process on multiplication with integers and facilitate teachers in choosing mathematics media. Used for teaching and learning processes in Class correctly Build students' knowledge and understanding in the creation of theoretical knowledge. 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 a good attitude in learning about mathematics for students
