Abstract

DC60 (28/10/52) Mathematics learning materials, factorization series. (Remove the joint) is a medium used by teachers in classroom teaching, it is a rectangular wooden board. With rectangular wooden frame The screen is divided into 2 channels, the first channel is a rectangle. To put a player on a rectangular wooden plate The width is x length and length is a unit, making the player a rectangular wooden plank. Has an area equal to unit axes, and the second space is a square. To insert a player that is a square wooden plate By stating Width is x length and length is b in length. The square-shaped player has Area is equal to bx units and when the player is a rectangular plank. Which has an area equal to ax, is attached to a player that is a square (4) plank with an area of bx units, resulting in total area equal to ax + bx units or equal to x (a + b) units by the player that is Rectangular wooden plate And a player that is a square wooden plate One side made different colors But the other side of each body is colored with the same white color and can remove the player as a disc Rectangular wood And a player that is a square wooden plate Exit from each channel and turn it over To illustrate the relationship of factorization (remove the common factor), use the relation of the player area. The invention is suitable for use as a classroom mathematics teaching material. About the enumeration property And facilitating teachers to choose Using mathematical materials used in learning Teach in the classroom properly, build students' knowledge and create proven knowledge. Theory from concrete to abstract Is a quality medium according to the principles of mathematics The materials are durable, cost-effective, reduce the time required to fabricate the media multiple times and facilitate storage. Creativity and a positive learning attitude about math for young students. Mathematics learning materials, factorization series. (Remove the joint) is a medium used by teachers in classroom teaching, characterized by a rectangular wooden board. With rectangular wooden frame The lines are screened into 2 boxes. The first box is a rectangle. For four players that are rectangular wooden planks The width is x length and length is a unit, making the player a rectangular wooden plank. Has an area equal to unit axes, and the second space is a square. To insert a player that is a square wooden plate By stating Width is x in length and length is b in length. Area is equal to bx units and when the player is a rectangular plank. Which has an area equal to ax, is attached to a player that is a square (4) plank with an area of bx units, resulting in total area equal to ax + bx units or equal to x (a + b) units by the player that is Rectangular wooden plate And a player that is a square wooden plate One side made different colors But the other side of each body is colored with the same white color and can remove the player as a disc Rectangular wood And a player that is a square wooden plate Exit from each channel and turn it over To describe the relationship of factorization (remove the common factor), use the relation of the player area. The invention is suitable for use as a material for teaching mathematics in the classroom. About the enumeration property And facilitating teachers to choose Using mathematical materials used in learning Teach in the classroom properly, build students' knowledge and create proven knowledge. The theory from the concrete to the abstract. Is a quality medium according to the principles of mathematics The materials are strong, durable, cost-effective and reduce the time it takes to fabricate the media multiple times and facilitate storage. Creativity and a positive learning attitude about math for young students.

Claims (1)

1. Mathematics learning materials, set of factoring (unity, common out) with a wooden board shape. Rectangle (3) rectangular wooden frame (1) (2) line screen (5) divided into 2 boxes. rectangle To insert a rectangular wooden player (6), set the width x length and length a unit, make the rectangular player (6) the area equal to the ax. The second box is a square. To insert a square wooden player (4) with width x length and length b, make square wooden player (4) the area equal to bx units. And when a rectangular player (6) with an area equal to ax is placed with a square player (4) with area equal to bx, the total area equal to ax + bx units. Or equal to x (a + b) units by the four (6) plank player and plank player Square shape (4), one side made in different colors. But the other side of each block is white all the same, and the rectangular wooden player (6) and the square wooden player (4) can be removed from each slot and turned over. To describe the relationship of factoring (singular, co-out), use the relation of area of the player, the color, the placement of the player.
