Abstract

DC60 (30/04/55) Mathematics series learning materials The wooden board and the wooden player represent the Pythagorean Theorem, a medium used by teachers in classroom instruction. With the appearance of a wooden board with a right triangle in the middle The first side of the right triangle board looks like a rectangular plank. A square with side lengths equal to the integral side one. There is a rectangular wooden frame around the board. Square wood To insert the player, a square wooden board whose side length is equal to the length of the side. Assemble the first right angle of the right triangle board. The second side of the right angle. Right triangle-shaped boards are square-shaped boards with equal sides. Assemble the second right angle. There is a rectangular wooden frame around a square wooden board. To insert the player Planks formed by dividing the area of a square-shaped plank with side lengths equal to the angular side. The second scene follows: Drag a line segment from the top left corner of the composite square plank. The second right angle to the right side of the square board. The second right side of the square. Is the length of one quarter of the side length of a square plank, the second right angle, and Drag a segment of the line from the upper-right corner of the second rectangular plank. To the bottom of the square plank, the second right side is one quarter of the length of the square plank. The second right side gives the area. It is a geometric figure to fit four players, which this invention is suitable for use as a medium. Teaching mathematics in a class on the origin of formulas and how the Pythagorean theory relates. And facilitate teachers in choosing to use math materials used in their classroom teaching Correctly and appropriately build students' knowledge and understanding in creating knowledge that proves the theory. From concrete to abstract It is a medium of quality, mathematically correct, material that is strong, durable, reduces costs and reduces the time required to fabricate media many times and is convenient to store.

With the appearance of a wooden board with a right triangle in the middle The first side of the right triangle board looks like a rectangular plank. A square with side lengths equal to one right side. There is a rectangular wooden frame around the board. Square wood To insert the player, a square wooden board with side length equal to the length of the side Assemble the right angle on one side of the right triangle board. The second side of the right angle. Right triangle-shaped boards are square-shaped boards with equal sides. Assemble the second right angle. There is a rectangular wooden frame around a square wooden board. To insert the player Planks formed by dividing the area of a square-shaped plank with side lengths equal to the angular side. The second scene follows: Drag a line segment from the top left corner of the composite square plank. The second right angle to the right side. A square plank. The second right side joins the right side. Is the length of 1/4 of the side length of the second right-angled square board and Drag a segment of the line from the upper-right corner of the second rectangular plank. To the bottom of the square plank, the second right side is about 1/4 of the length of the square plank. The second right side gives the area. It is a mathematical pattern to fit four players, which is suitable for use as a communication tool. Teaches mathematics in a class on the origin of formulas and the relationship of the Pythagorean theory. And facilitate teachers in choosing to use mathematics materials that are used in classroom teaching Correctly and appropriately build students' knowledge and understanding in creating knowledge that proves the theory.
