Abstract

DC60 (30/04/55) Mathematics series learning materials Factoring all differences to the third power with a wooden block. Rectangle It is a medium that teachers use in teaching and learning in the classroom. Which looks like a square wooden bar A total of 8 right angles to illustrate the factor-factorization of all to the third power. By linking from the relation of the volume of the rectangular shape to the correlation formula of Factor all difference numbers to the power Which this invention is suitable for use As a learning medium for teaching mathematics in the subject class Factoring all differences to the third power and facilitating teachers in choosing the correct and appropriate mathematical materials for classroom instruction, students' knowledge in building up knowledge that is appropriate for classroom instruction. Proving the theory From concrete to abstract It is a medium of quality, mathematically correct and durable materials. Reduce costs and reduce the time required to fabricate media multiple times and conveniently store. It can foster creativity and a positive attitude in learning about mathematics for students.

Claims (1)

1. Mathematics learning materials set Factoring all differences to the third power with a wooden stick. Rectangular shape With the appearance of a total of 8 rectangular wooden bars that are gathered together as A cubic shape, given that its width is a, length is a, and height has length a, a cube has a volume of a x a x a cubic unit, or a3 cubic unit. The first piece is the largest cube (1) of the width. The length is a - b, the length is a - b, and the height has a - b length. The largest rectangle (1) has a volume equal to (a - b) 1 unit cube. The second is a rectangular block with a minor size (2) given its width. Length is b, length is a - b, and height has length a - b, giving the minor rectangular bar (2) this dimension. Equal to bx (a - b) x (a - b) 2 cubic units, or b (a - b) 3 cubic units, the third is a rectangular wooden bar (3) defined as its width and length. It is b units of length with length b and height with length a - b, giving this rectangular stick (3) the same volume as bxbx (a - b) cubes, or b2 (a - b). Three cubic units and the fourth are small cubic blocks (4) given the length of b, length b, and height b. Makes (4) small rectangular wooden bars (4) the same volume as 1 unit cube bxbxb or b3 unit cube.
