Abstract

DC60 (06/06/54) Mathematics learning materials. Multiplication property It is a medium that teachers use in teaching and learning in the classroom. It is a rectangular wooden board. With rectangular wooden frame Blocks are made in a wooden board. A total of 4 rectangles in the bottom row, 2 blocks on the right side. Horizontal screens 5 lines and 6 vertical lines screen sizes of width Each row the same width And the length of each row is the same as a square. To insert a wooden player A total of 20 square blocks and blocks on the left side, 5 horizontal lines and 6 vertical lines are screened with the same width of each row. And the length of Each row is equal to a square. To put a total of 20 square-shaped wooden players equal to the square-shaped players of the blocks on the right There are 2 blocks in the top row, where the blocks on the right side have 4 horizontal lines and 5 vertical lines with the same width of each row. And the length of each row is the same as the figure Square To put a player in a total of 12 square-shaped wooden blocks, and the blocks on the left have To screen 4 horizontal lines and 5 vertical lines with the width of Each row the same width And the length of each row is the same as a square. To insert a wooden player A total of 12 square blocks of the size of the player is the square wooden plank of the block on the right by the square wooden player painted on both sides. And can remove the player that is A square plank leaves a hole in each slot. And can be reversed To describe and express Relationship of knowledge of multiplicative properties Will take into account the placement and number of players in the wooden shape. Square Which this invention is suitable for use as a medium for teaching mathematics in A class on multiplication properties And facilitate teachers in choosing to use mathematical materials Correct classroom teaching builds students' knowledge and understanding. Knowledge that proves the theory From concrete to abstract It is a medium of correct quality. Academic mathematics The material is strong, durable, reduces costs and the time it takes to fabricate the media multiple times and convenient for storage. Fostering creativity and a positive attitude in learning about subjects Mathematics for students. Mathematics learning materials Multiplication property It is a medium that teachers use in teaching and learning in the classroom. It is a rectangular wooden board. With rectangular wooden frame A total of 4 blocks were made in a rectangular wooden plank, 2 in the bottom row, with the blocks on the right having 5 horizontal lines screened and 6 vertical lines of width. Of each row of the same width And the length of each row is the same as a square to put a player that is a total of 20 square-shaped planks and blocks on the left have 5 horizontal lines and vertical lines. Six lines have the same width of each row and the same length of each row as a square. To insert a total of 20 square-shaped wooden players that are the same size as the square-shaped players of the blocks on the right. There are 2 blocks in the top row, where the blocks on the right side have 4 horizontal lines and 5 vertical lines with the same width of each row. And the length of each row is the same as a square to put a total of 12 square-shaped wooden planks and blocks on the left side with 4 horizontal lines and vertical lines. The number of five lines has the same width of each row and the length of each row as a square. To put a total of 12 square-shaped wooden players that are the same size as the square-shaped players of the blocks on the right. By the player who is Square-shaped wooden planks painted on both sides And the player that is a square wooden plank can be removed from the slots in each box and can be reversed exactly. To describe and express the relationship of knowledge of multiplication properties, consider placing and the number of players on a square wooden plank. Which this invention is suitable for It is used as a classroom teaching material for properties of multiplication and to facilitate teachers in that They choose to use mathematics materials that can be used correctly and appropriately in classroom teaching and building knowledge. Understand the student's ability to create knowledge that proves the theory From concrete to abstract Is a medium that has Quality is correct according to academic mathematics principles. Materials that are strong, durable, reduce costs and reduce cycle time. Media must be fabricated many times and convenient for storage. Foster creativity and a positive attitude in Learn about maths for young students.
