TH5685C3 - Mathematics learning materials Switching property set at multiplication - Google Patents

Abstract

DC60 (28/10/52) Mathematics learning materials, switching properties of multiplication. It is a medium that teachers use in teaching and learning in the classroom. It is a rectangular wooden board. With rectangular wooden frame There is a split screen. The horizontal line is 3 rows, each row in the horizontal line is screened into 4 cells. The width of each row is the same width. And the length of each row is the same as a square. To put the player at There are 12 pieces of colored square wooden boards on both sides of the same size. The players are colored square wooden planks on both sides. The player can be removed from the slots in each compartment and can be flipped back exactly. And the player is a square wooden plate painted on both sides Each body on one side is colored the same color, the other side is colored all the same white. To characterize the relationship Of the commutative property at multiplication To connect to the content of the switching properties of multiplication Which this invention contains It is suitable for use as a mathematics teaching material in the classroom on the alternating properties of multiplication and to facilitate teachers in choosing the math materials used in their classroom instruction. Studying correctly and appropriately builds students' knowledge and understanding of the proof of theory from concrete to abstract. Is a quality medium according to the principles of mathematics Materials that are strong, durable, reduce costs, and reduce the time it takes to create media multiple times and conveniently store them, foster creativity and a positive attitude in mathematics learning for students.
