TH5841C3 - Math media Factorization set (Difference of the second set of squares) - Google Patents

Abstract

DC60 (02/08/53) Mathematics learning materials. Factorization set (Squares Difference Set 2) is a mathematics learning tool used by teachers in teaching and learning processes in the classroom, which looks like a square wooden board. Square frame With screen dividing line by Screen the lines on the diagonal lines of the wooden board. But not reach the other corner, number 1 line, and touch the screen line in the diagonal line of the board of the first screen line 2 lines to place the player that is a total of 3 pieces of wood formed by the screen Intersecting by The large player looks like 2 equal sized trapezoidal planks and the It is a small square-shaped plank, equal to the size of 2 screen lines, touching the screen line in the diagonal of the first screen line, 1 piece by the color player. On both sides, each player makes a different color for every player. And can remove all players from the channel And then put the two large trapezoidal players together in equal sides Forms a rectangle to describe and factor-factor the difference squares. This invention is suitable for teachers and students to use as a learning material and to organize the mathematical teaching process on quadratic factor factorization. And facilitate teachers in choosing to use math materials Used in the process Correct classroom teaching builds students' cognition to build. Knowledge that proves the theory from the concrete to the abstract. It is a medium that has quality, mathematically correct, cost reduction and time to create or produce media from poor quality materials and convenient for storage. Build creativity And a positive attitude in learning about subjects Mathematics for students. Mathematics learning materials Factorization Set (Squares Difference Set 2) is a learning material used by teachers to organize classroom teaching and learning processes. Which looks like a square wooden board Square frame The dividing line is screened by one number of screened lines on the diagonal of the wooden board, but not at the other corner, and the tangent lines on the diagonal of the wooden board of the first screen line 2 lines for Place the player that is a total of 3 planks formed by the screen lines intersected by the large player, two pieces of the same size trapezoidal planks and a smaller square-shaped player. Equal to the square of 2 screen lines touching the screen line in the diagonal of the wooden board of the first screen line 1 piece by the players paint on both sides, each player makes a different color for every player. And all players can be removed from the box, and the two large trapezoidal players can be placed together in equal sides. It formed a rectangle to describe and represent the quadratic factoring. This invention is suitable for teachers and students to use as learning materials. It is used to organize the learning process, math insertion on the quadratic factor factorization, and facilitate teachers in choosing mathematical media. Which is used to properly organize the classroom teaching process, to build students' knowledge and understanding in creating knowledge that is proof of the theory from concrete to abstract Is a quality medium Mathematically correct, cost reduction and less time creating or producing media from poor materials. And convenient to store Build creativity And a good attitude in learning about mathematics for students
