Today is math class, and the teacher talked about an interesting math topic, which made me more interested in math. The topic is this: there is a rope with a length of 12 meters. It should be cut into three sections, so that the three sections can form an equilateral triangle. What is the length of each piece of rope? I began to think, assuming that the length of each rope is x, then the sum of the lengths of the three ropes is 3x. Since an equilateral triangle is to be formed, the length of each rope is equal, that is, x = 4m.
So I cut the rope into three lengths of 4 meters and put them together, and found that they can really form an equilateral triangle. Through this topic, I deeply realized the charm of mathematics, which can make us have fun in thinking and help us solve practical problems. I decided to study math harder and explore more interesting math problems.
Math diary introduced:
Math diary is a way to record mathematics learning and thinking. He usually records his thoughts in mathematics learning in the form of a diary, including solving mathematical problems, summarizing mathematical knowledge and training mathematical thinking. Math diary can help students better understand and master mathematical knowledge, improve their mathematical thinking ability, and also cultivate their self-reflection and recording ability.
Math diary's content can be recorded according to personal interests and learning situation, and it can be a summary of mathematical knowledge explained in class, a reflection and solution of mathematical problems he has done, and a summary and application of mathematical thinking methods. Through math diary's records, students can better find their own math problems and deficiencies, make timely adjustments and improvements, and improve the effect of math learning.
