ORGANIZATION OF THE LEARNING STANDARDS

ORGANIZATION OF THE LEARNING STANDARDS

Learning Standards define what a child should know and be able to do in every class for every subject. The Learning Standards for Mathematics are a connected body of such mathematical understandings and competencies broken up class wise. They describe a comprehensive base for all students stating the knowledge, understanding and skills that they should acquire for much used life skills. The Learning Standards give a common foundation for all students. However, all students are not alike. The talent and interest of those who are gifted should be kept engaged and those with special educational needs must be given the support to acquire a good understanding of important mathematics.
                                                                                                                                                              The Learning Standards for K.G. to class 8 have been organized into the following five sections. The sections broaden the scope of school mathematics. It is not acceptable for elementary school mathematics to be concentrated solely on arithmetic or for high school mathematics to be concentrated solely on algebra and geometry. Appropriate material from each section should appear at each class level. Together, the sections describe the range of mathematics important for today's students. Wherever possible, the sections are meant to be taught and learnt in a integrated manner. Real mathematical problems rarely involve just one section. Rather, they demand that the problem solver integrate ideas from several sections to arrive at a meaningful result.  A brief description of each section is as follows -

I.      Numbers and Operations This section develops a sense of quantity, facility with computing and communication in the language of numbers. It describes numbers, their properties, relationships and calculations with them. It includes counting objects in a collection, relating the numbers e.g. ordering, carrying out basic operations on them and extending to complex situations gradually like factors, multiples, ratios and so on. It includes properties, special numbers (1, 0, reciprocals, inverses) and different kinds of numbers (integer, rational, real). Students learn to think and communicate in the language of numbers (i.e. use various notations, number sentences and verbal expressions for number sentences). They become familiar with different techniques for computing algorithmic using paper and pencil, mental, estimation. In the end, students have an understanding of how simple elements give rise to a structure capable of representing relations among quantities in the real world and in the imagination. This section permeates all of mathematics.

II.      Patterns and Algebra This section describes patterns and relationships using general arithmetic by using variables to range over the numbers. Patterns are a backbone of mathematics. The patterns section explores informal patterns in early classes and formal numeric patterns gradually. It helps in recognizing, explaining and extending the many kinds of relationships among quantities. Thoughtful experiences with a variety of patterns, formal and informal, helps students make patterns part of their intellectual repertoire.
Algebra is generalized arithmetic. It helps make the specific into universal, helps describe situations, derive relationships with elegance and power, manipulate expressions and find solutions. By itself it is the language of variables, operations, and symbol manipulation. Starting with missing addend problems, students slowly develop the ability to use algebra as a language. Every other section uses algebra to symbolize, clarify and communicate thus integrating this section with others. It is important, therefore, to use algebra in the context of problems and situations arising in other sections. Specifically, students need the tools of algebra (such as formulas, functions, and equations) to describe and clarify geometric relationships; and they need the vehicle of geometry to provide graphic illustrations for algebraic relationships.

III.      Measurement This section describes and compares everyday phenomena using direct or indirect measurement. It is used in all occupations and in everyday life to compare quantities. Work in measurement begins with comparison: bigger-smaller, heavier-lighter, warmer-colder.  Numbers are assigned to quantitative aspects of the world by being compared to a scale of non-standard units (e.g. paper clips, paces, heartbeats, etc.) and then standard units such as international metric system. By focusing on obtaining numbers through direct interaction with the universe, the measurement section makes a physical connection between numbers and the world through the action of the student. Students learn to create nonstandard units to help with the comparison. Later, they learn about standard system of units especially for time, distance, weight, volume, area and temperature. This section is closely allied with geometry through measurement of length, area, and volume. Measuring diverse quantities makes connections within mathematics, especially to statistics, and outside, to the natural and social sciences.

IV. GeometryThis section links mathematics to space and form in the world around us and in the abstract. In this section students are exposed to and investigate two-dimensional and three-dimensional space by exploring shape, area, and volume; studying lines, angles, points, and surfaces; and engaging in other visual and concrete experiences. In the early classes this process is informal and highly experiential; students explore many objects and discover and discuss the attributes of different shapes and figures. Older students gradually build on this foundation of hands-on experiences. They become more familiar with the properties of geometrical figures and get better at using them to solve problems. They explore symmetry and proportion and begin to relate geometry to other areas of mathematics - to the benefit of both. For example, graphical representations of functions can help explain and generalize geometric relationships while geometrical insights inform the study of functions. As students become more familiar with geometrical figures, they are better equipped for mathematical argumentation in that field. They focus on making convincing arguments with a rigor appropriate to the situation rather than on being forced into two-column proofs. The goal is to develop fluency with basic geometrical objects and relationships and to connect that fluency with spatial reasoning and visualization skills.

V.     Statistics This section describes the pictorial representation of data. It describes collecting, organizing, representing, analyzing the data, making inferences which give an insight into the data and solving problems involving uncertainty. In an age of rapid communication and immediate access to information, data is abound. Descriptive statistics help students learn to collect and organize information in a variety of graphs, charts, and tables to make those data easier for the students and others to comprehend. Students also learn to interpret data and to make decisions based on their interpretations. Probability is a part of this section because statistical data are often used to predict the likelihood of future events and outcomes. Students learn probability, the study of chance, so that numerical data can be used to predict future events as well as record the past. A command of statistics and probability is essential in all aspects of adult life.
