Abstract

DC60 Mathematics Learning Materials Factoring sets, total squares, and differences All to the square It is a medium that teachers use in teaching and learning in the classroom. With a wooden frame Square shape With a total of 4 players placed in a wooden frame Set the length of the side The four sides of the square wooden frame have a length of a unit, with the first player having Is a large square wooden player Set the lengths of the four sides of the player racket. The large square shape is a-b in length, making it a square wooden player. The large size has an area equal to (a - b) 2 square units placed at the bottom corner of the square timber frame. The second player is a smaller square wooden player than the first. Set to length Each side of the small square wooden player has a length of b, making the large square wooden player an area equal to b2. The unit square is placed in the upper corner of the frame. Square wood With one side of the wooden player in a small square shape attached to the corner One side of the large square wooden player. And the third player and the fourth player looks Is a rectangular wooden player of the same size Set the length of the third player and The fourth player piece is the same length as the first player's side length, a - b length, and sets the width of the third player and the fourth player to the same length. Long side The second piece of the player, that is, b in length makes the third rectangular player And the fourth has an area equal to (a - b) x b square units, and the four wooden players can be removed. Out of the square wooden frame can be placed alternately. To describe the relationship of areas of Each wooden player associates all of the positive number factorization formulas. The square is (a + b) 2 = a2 + 2ab + b2, and the difference number factorization formula. The total square is (a-b) 2 = a2 - 2ab + b2, which is suitable for use as Teaching materials for teaching mathematics in class. Factoring all sums squared And all differences are squared. And facilitate teachers in choosing to use math materials That are used in teaching and learning in the classroom to properly build knowledge and understanding of Students in the creation of knowledge that proves theory From concrete to abstraction is a quality medium according to the principles of mathematics. The materials are strong, durable, lower costs and the time it takes to fabricate the media multiple times and convenient for storage. Strengthen the mind A creative and positive attitude to learn about mathematics for young students. Mathematics learning materials Factoring sets, all sums of sums and all differences squared. It is a medium that teachers use in teaching and learning in the classroom. Which looks like a square wooden frame With a total of 4 players placed in a wooden frame Set the lengths of all four sides of the square wooden frame to a unit length, with the first player being a large square wooden player. Assign the lengths of the four sides of the large square wooden player to be a - b lengths, giving the large square wooden player an area equal to (a - b) two square units placed at the bottom corner of the square wooden player. Square wooden frame The second player is a smaller square wooden player than the first. The lengths of the four sides of the small square wooden player have a length of b, giving the large square wooden player an area of b2.The unit square is placed at the top corner of the square wooden player with its corners. One of the small square wooden players is attached to one corner of the large square wooden player. And the third player and the fourth player character a rectangular wooden player of the same size, requiring the length of the third player and the fourth player to be equal to the length. The first player piece is a - b, and sets the width of the third player and the fourth player to be the same length as the second player's side length. It is b in length, allowing the third rectangular wooden player and the colored one to have an area equal to (ab) xb. The unit square and the four wooden players can be removed from the square wooden player alternately. To describe the relation of area of each wooden player, link the factorization formula of all the positive numbers square to (ab) 2 = a2 + 2ab + b2 and the separation formula. The factor of all difference numbers squared is (ab) 2 = a2-2ab + b2. This invention is suitable for use as a material for teaching mathematics in the subject class. Factoring (all squares and all differences squared) and facilitates teachers in choosing the correct math materials used in classroom instruction. Appropriate to build students' knowledge and understanding to generate knowledge that is proof of theory. From concrete to abstract 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. It can foster creativity and a positive attitude in learning about mathematics for students.
