Measurement - Mathematic Reform

Most students are enthusiastic and interested in learning mathematics, and they are in the third grade. Indeed, nearly three quarters of the fourth grade in the United States report mathematics (NCTM, 143). This may be a very important moment for children to be interested in what they are learning. If the work is too tedious to be too dull, it will have a negative impact on their perception of the subject in later life. If students from 3rd grade to 5th grade have fun mathematical material, it can help them keep on getting involved in that topic. One of the main content fields currently being handled is measurement. Measurement is one way teachers introduce the usefulness and practicality of mathematics to students. In the measurement, you need to compare the properties (distance, surface, volume, mass, time, temperature) or known criteria between the two objects. Measurements also introduce students important concepts such as accuracy, approximation, tolerance, error and size. With lesson plans from kindergarten to 12th grade, students can understand the measurable properties of objects and units, systems and processes of measurement. In addition, appropriate techniques, tools and formulas apply to determine the measurements (NCTM, 171). In this article I will explain how these ideas were developed from 3rd grade to 5th grade.

The first and most fundamental measure of this level is the ability to understand the measurement characteristics we use everyday. These attributes include length, area, weight, volume, magnitude of angle, and so on. Understanding these variables is important. Because they are often used throughout life. If the student better understands these measured variables, the next goal is to let them decipher the correct measurement method. Choosing the right unit to measure variables such as length, area, weight, etc. is as important as understanding its meaning. For example, if a student tries to measure the length by angle or area, it is meaningless to know that the length is the distance between two points. It is important to understand the correct way to measure variables. This idea also provides metrics to understand the basic way to describe the need for standard units and attributes. For this, students must be familiar with standard units of custom and metric systems.

Unit planning project focuses on mathematical measurements and students examine habits and standard measurement units, understand linear distance measurements, and compare measurement units using the acquired knowledge. Unit programs also allow you to prepare additional unit measurements such as time, capacity, weight, etc. for students by introducing various measurement tools to measure real world objects related to them It is aiming. Therefore, it is clear that this unit is mathematically important. Because in the real world there are no measurements and standards that people can not get. Measurement is life skill. If our society does not measure it, what will it use? After encountering such a question in the first activity of this module, the student will soon understand the importance of the measurement and its usage.

In some course projects, we are working on the development of mathematics through measurement rather than digital concepts. The Measure Up project (S lovin & Dougherty, 2004) is not a superfeature that solves the problem situation, but by initial unit of mathematics by establishing measurement units and symbolic expressions focusing on structural features such as patterns and relationships Develop. A recent study on early algebra (Carraher, Schliemann, Brizuela, and Earnest, 2006) suggests that young students generalize and develop abstract mathematical methods that reflect mathematical structures given appropriate opportunities You can learn that you can learn. Supplementary research supports the notion that young students can develop functional thinking (Blanton & Kaput, 2005). In other studies for young students, the importance of structural relationships in the development of analogy is emphasized (English, 2004).
