Abstract

DC60 is a set of materials for teaching fractions, percentages, decimals (using colored rubber bands) based on this invention. As a medium for learning mathematics That teachers use in the assembly of the process Classroom teaching Which looks like a square wooden board With a wooden pegs that There is a spiral around the body of a wooden peg pin in a square wooden board. Which the wooden pegs The horizontal and vertical strands of the wooden pegs are 11 rows equal, and the spiral-shaped pegs surrounding the wooden pegs are equal spacing. All squares with different colored rubber bands are used to tighten the threaded wooden pins. Around the body of the wooden pegs In the form of different polygons to clearly see the number of squares that the rubber bands of different colors This invention is suitable for teachers and students to use. It is a learning medium and used for organizing mathematical teaching process on fractions, percentages, decimals and facilitating teachers in choosing to use mathematics media used. To properly organize the classroom teaching and learning process. Build up the understanding of Students in the creation of knowledge that proves the theory From concrete to abstract It is a medium of quality, correct, mathematically, reduce costs and reduce time to create or produce media From poor quality materials And convenient to store And fostering creativity and a positive attitude in learning about mathematics for students.
