Abstract

DC60 Mathematics Learning Materials Factorization set (Set of all differences to the third) is a medium used by teachers to Teaching in the classroom It is characterized by a rectangular wooden bar, all 4 pieces that combine to form. A cubic square, given that its width is a, length is a, and height has length a, a cube has the same volume as the axaxa cubic, or a3 cubic unit, where one is the bar. The largest rectangular wood The length is a - b, the length is a unit, and the height is a unit of length. This largest has a volume equal to (a - b) x a x a cubic unit. The second piece is a rectangular wooden bar with a minor size, defined as the width, length b, length a - b, and height a unit length, making the bar a rectangular shape. This smaller size has a volume of bx (a - b) xa cubic units. The third piece is a rectangular wooden bar. The width has the length b, the length is b, and the height has a - b length, giving this rectangular bar a volume of b x b x (a - b) cubic unit. And the fourth is a rectangular wooden bar, the last one looks in shape. Cube The width is b, length is b, and height has length b, so the last rectangular wood looks a cubic shape with a volume of b x b x b cubic units. To explain and show factorization (A set of all differences raised to the third) in relation to the volume of the rectangles. With a different color To the correlation formula Factoring all difference numbers raised to the third power, that is (a - b) raised to the power of 3 = a3 - 3a2b + ab2 + b3, this invention is suitable for use as a material for teaching mathematics in the classroom. Learn about separating components (sets of all differences to the third power) and facilitate teachers in choosing math materials to use. Assembling the classroom teaching properly, creating knowledge and understanding of the students to build. Knowledge that proves the theory From concrete to abstract It is a medium of quality, mathematically correct and durable materials that reduce costs and reduce the time it takes to create media multiple times and is convenient for storage. Foster creativity and positive attitude in learning about mathematics for students. Mathematics learning materials. Factorization set (Set of all differences to the third) is a medium used by teachers to Teaching in the classroom It is characterized by a rectangular wooden bar, all 4 pieces that combine to form. A cubic square, given that its width is a, length is a, and height has length a, a cube has the same volume as the axaxa cubic, or a3 cubic unit, where one is the bar. The largest rectangular wood The length is a - b, the length is a unit, and the height is a unit of length. The largest has a volume equal to (a - b) x a x a cubic unit. The second part is a rectangular block of smaller dimensions, defined as the width, length b, length a - b, and height a unit of length, making the bar a rectangular shape. This smaller size has a volume of bx (a - b) xa cubic units. The third piece is a rectangular wooden bar. The width has the length b, the length is b, and the height has a - b length, giving this rectangular bar a volume of b x b x (a - b) cubic unit. And the fourth is a rectangular wooden bar, the last one looks in shape. Cube The width is b, length is b, and height has length b, so the last rectangular wood looks a cubic shape with a volume of b x b x b cubic units. To explain and show factorization (A set of all differences raised to the third) in relation to the volume of a perpendicular rectangle With a different color To the correlation formula Factoring all difference numbers raised to the third power (a - b) 3 = a3 - 3a2b + ab2 + b3, this invention is suitable for use as a material for teaching mathematics in the subject class. Separation of components (sets of all differences to the third power) and facilitates teachers in choosing the math materials used. Assembling the classroom teaching properly, creating knowledge and understanding of the students to build. Knowledge that proves the theory From concrete to abstract It is a medium of quality, mathematically correct and durable materials that reduce costs and reduce the time it takes to create media multiple times and is convenient for storage. It can foster creativity and a positive attitude in learning about mathematics for students.

Claims (1)
