Abstract

DC60 Mathematics learning materials, addition of inequality series It is a medium that teachers use in teaching and learning in the classroom. It is a rectangular wooden board. With rectangular wooden frame Inside, two rows are divided horizontally, in the top row there are blocks. The left block is a fabric rectangle. To put the player at Each rectangular plank is 1 piece, set the size of the rectangular plank player a value and the right block is a rectangle equal to the left block. But has a longer side length Left block To insert a player that is a wooden piece of rectangular pieces, set the size of the player that is A rectangular wooden plank is equal to b and has the mathematical sign, the less-than sign in between. Both blocks In the bottom row, blocks are made into 2 blocks, the left block is rectangular, the line is screened in 2, the first one is the same size as the top left block. And the second part Is a square with The size is equal to the width of the block. To insert a player that is a rectangular wooden plank, number 1, set the size of the player that is a rectangular wooden plank equal to a and put a player that is a rectangular wooden plank amount 1 piece set the size of the player that is It is a rectangular piece of wood equal to c, with the right block being a rectangle, screened in 2 halves, with the first being the same size as the top right block. And the second is a square equal to the width of the block. To insert a player that is a square wooden plank, set the size of the square wooden player b and put the square wooden player player on. One square plank is assigned the size of the rectangular wooden plank player to be equal to c, the rectangular wooden player player and the square wooden player player are colored on both sides and can be removed from the player. Each block can then be turned over. And a player that is a rectangular wooden plate each One side made the same color. But the other side of each body is colored the same white color. And the player with a sheet Each square-shaped stick on one side is colored the same, but the color is different from the rectangular wooden player, and the other side is all white. To describe and illustrate the addition of the inequality, size, color and layout are used as a rectangular wooden plank and a square wooden player with a defined mathematical symbol. Which this invention is suitable for use as a study material Teaching mathematics in the classroom The addition of inequality and facilitation of teachers in Choose the correct and appropriate mathematical materials used in classroom teaching and building knowledge. Understand students' building on knowledge that is proof of theory. From concrete to abstract Is a medium that has Quality is correct according to academic mathematics principles. Materials that are strong, durable, reduce costs and reduce cycle time. Must invent the media many times And convenient to store Foster creativity and a positive attitude in Learn about maths for young students. Mathematics learning materials, addition of inequality series. It is a medium that teachers use in teaching and learning in the classroom. Which looks like a rectangular wooden board With rectangular wooden frame Inside, two rows are divided horizontally, in the top row there are blocks. The left block is a fabric rectangle. To put a player that is a rectangular wooden plank, amount 1 piece, set the size of the player that is a square cloth Where a value is equal to a And the right block is a rectangle that is the same width as the left block. But has a longer side length than the left block To insert a player that is a rectangular wooden plank, 1 piece of cloth, set the size of the cloth square player player is equal to b and the mathematical sign is the less sign in between. Both blocks In the bottom row, 2 blocks are made, with the left block being fabric squares. The line is screened into 2 parts, the first part is the same size as the top left block. And the second part It's a square that is equal to the block width. To put a player that is a rectangular wooden plank amount 1 piece set the size of the player who is a square cloth is equal to a and put a player that is a square wooden plank number 1 set the size of the player This is a fabric rectangle with a value of c, where the right block is a fabric rectangle. The line is screened into 2 parts, the first part is the same size as the top right block. And the second part It's a square that is equal to the block width. To put a player that is a square wooden plank, number 1 piece set the size of the square wooden player is equal to b and put the player who is a square wooden plank number 1 set the size of the player that is It is a square-shaped wooden plank with a value of c. The player is a square-shaped wooden plank, and the player is a square-shaped wooden plank painted on both sides. And the player can be removed from the blocks in each block and turned over. And a player that is a rectangular wooden plate, each cloth on one side, the same color But the other side of each body is colored the same white color. And the square-shaped player, each side is colored the same, but the color is different from the square-shaped wooden player. And the other side of each body is painted the same white color To describe and express the addition of the inequality, size, color, and a rectangular playing player are used and the square wooden player is used. With the specified mathematical marks This invention is suitable for use as a teaching material for mathematics in the classroom. The addition of inequality and facilitates teachers in choosing the correct and appropriate mathematical materials used in classroom teaching, building students' knowledge and understanding in creating knowledge that is appropriate Prove 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 It can foster creativity and a positive attitude in learning about mathematics for students.
