TH5807C3 - Math media Factorization set (Difference of square 1) - Google Patents

Abstract

DC60 (02/08/53) Mathematics learning materials. Factorization set (Squares difference set 1) This is a mathematics learning material used by teachers in organizing teaching and learning processes in the classroom. A square wooden board Square frame With screen dividing line By screen lines inside Vertical on the right side of the wooden board, 1 line and the horizontal screen in contact with the vertical screen line At the bottom right of the hand, a number of one line is to place all 3 planks formed by the intersection of the screen line by the largest player having one rectangular plank and the player that It is a small rectangular piece of wood the size of the vertical screen line on the right side of the board. One piece of wood to the horizontal tangent line and a player that is a small square-shaped plank whose size of the side of the player is equal to the width of the side of the player that is one small rectangle made by the player. Color both sides Each player is colored differently and every player can be removed from the slot and then brought in both rectangular, large and small pieces. Put together in equal sides. Rectangular This invention is suitable for teachers. And students in use as learning materials And used in the mathematics teaching process on the factorization of the difference of squares And facilitate teachers in choosing to use mathematical materials that can be used to correctly organize the teaching and learning processes in the classroom; Students' understanding of the knowledge that proves theory from concrete to abstract Is a quality medium Mathematically correct, cost reduction and media creation or production time reduction. From poor quality materials And convenient to store Build creativity And a positive attitude in It's learning about mathematics for young students. Media set factorization (Squares difference set 1) This is a mathematics learning tool used by teachers. Assembly of classroom teaching and learning processes It looks like a square wooden board with a square frame. With screen dividing line By screen one vertical line on the right side of the wooden board and one horizontal screen touching the bottom right vertical screen line 1 line to place the player that is a total of 3 pieces of wood formed by the intersecting screen line. By a large player The most features are 1 rectangular wooden planks and a player that is a rectangular plank. The small one is the size of the vertical screen line on the right side of the board. To the tangent line in the horizontal number 1 and the player is a small square wooden plank. Which has the size of the side of the body Play equal to the width of one small rectangular player's width, with both sides colored by the player. Each player has a different color for every player. And can remove all players from Box and take the player that is a square Both large and small canvases are placed together in equal sides to form a rectangle. This invention is suitable for teachers and students to use. As a learning medium And used to organize mathematics teaching process on separating (squares difference) and facilitating teachers in choosing the mathematics media used. To facilitate the organization of teaching and learning processes in the classroom correctly. Build up the understanding of Students in the creation of knowledge that proves 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 material And convenient to store Build creativity And a good attitude in learning It's about mathematics for students.
