Abstract

DC60 (04/09/58) Mathematics learning materials. Equal number subtraction series. (Practice 2) is a medium used by teachers in learning. Classroom teaching It is characterized by a rectangular wooden board on both sides with a rounded shape. At the bottom there is a section connected to the base that looks like a rectangular wooden plank. Around the middle of the board Rectangular shape on both sides is rounded It is screened horizontally and the numbers from 0 to 10 are screened evenly and there is a wooden peg player with a round twist. Embroidered with Screen numbers from 0 to 10, a total of 10 pieces, and there are rubber bands of various colors to cinch. Play wooden pegs that look In a spiral In describing and correlating the principle of equal negative numbers. It is used to place rubber bands of different colors for fasteners, play wooden pins with a spiral pattern around, showing the preliminary equal number of subtractions. Then consider their relationship with The corset plays a wooden peg that looks like a round twist. Which this invention is suitable for use as a study material Teaching mathematics In my class on the principle of subtraction of basic equal numbers And facilitate teachers In order to choose appropriate mathematical materials used in classroom teaching, revise the invention summary 4/9/2015 Mathematics learning materials, equal number subtraction series. (Practice 2) is a medium used by teachers in learning. Classroom teaching It is characterized by a rectangular wooden board on both sides with a rounded shape. At the bottom there is a section connected to the base that looks like a rectangular wooden plank with cloth. Around the middle of the board Rectangular shape on both sides is rounded It is screened horizontally and 0 to 10 numbers are green, evenly scaled, and there is a round helical peg player. Embroidered with Screen numbers from 0 to 10, a total of 10 pieces, and there are rubber bands of various colors to cinch. Play wooden pegs that look In a spiral In describing and correlating the principle of equal negative numbers. It will be used to place rubber bands of different colors for fasteners, play wooden pegs that have a twist around it. Show initial equal count subtraction. Then consider their relationship with The corset plays a wooden peg that looks like a round twist. Which this invention is suitable for use as a study material Teaching mathematics In subject class Principle of subtraction of equal numbers And facilitate teachers In order to properly use mathematics materials used in classroom teaching --------------------------- -------------------------------------------------- -------------------------------------------------- ---------------- Mathematics learning materials The equal number subtraction set (set 2) is a medium used by teachers in classroom teaching and is characterized by a rectangular wooden plank with a rounded shape on both sides. At the bottom there is a section connected to the base that looks like a rectangular wooden plank with cloth. Around the middle of the board Rectangular shape on both sides is rounded There is a horizontal line screen and a number of green 0 to 10 is evenly divided, and there is a wooden peg player with a round spiral pattern that corresponds to the number screen from 0 to 10. All 10 pieces and there are rubber bands of different colors for corset to play with wooden pegs. That looks like a spiral around To describe and express the relationship of the equal number subtraction principle, different colored rubber bands are used for the corset, play with the secondary threaded wooden pins, show the initial equal number of loops, and consider the relationship with the corset. Play a wooden peg that looks like a round twist. Which this invention Suitable for use as a material for teaching mathematics In subject class The principle of subtraction of numbers Equal And facilitate teachers in choosing to use mathematical materials used in learning Correct classroom teaching builds students' cognition in building knowledge. That is a proof of theory From concrete to abstract Is a medium of quality correct according to academic principles Mathematical The material is strong, durable, low cost and reduces the time required to fabricate the media multiple times and is convenient for storage, fostering creativity and a positive attitude in subject learning. Mathematics for students.
