Math Blog on Grade V

Hello Friends,Previously we have discussed about list of rational numbers and today we are going to learn about the mathematics of the grade V of indian certificate of secondary education board. We will learn about some few discussion of syllabus of fifth standard mathematics. Grade V is the level of learning, after that the schooling ends, so these are the end years of the school for any child.
In grade fifth, we learns about the numbers as read the number having multiple digits like 100000 and locate, represent, identify and compare such numbers by the use of expanded or regular form of them. We should have the proper understanding of the place values for 0-4 places in number to the right and left places. We should be able to perform addition, subtraction, division and division the decimals. We should have the proper understanding of converting fractions to decimals related values. We can make the selections for the strategies for problem solving and we should also have mathematical thinking in problems solving. In term of measurements we should have understanding of length unit like inches, feet, yards, miles, millimeters, centimeters, meters, and kilometers and we also the proper use of these terms in problem solving. We should have ability to make rounds accurately in measurements. In term of geometry we learn about the plane figures, solid geometry, area, surface area, volume, perimeter, and circumferences etc. so for this we have the proper understanding of coordinate system on either map or grid.(To understnd geometry in more precise manner ,click here)
The grade V also includes the learning and modeling 2d and 3d objects. We learn about different types of polygons, symmetry of planes, and sides of them. It includes the use of venn-digrams to short the shapes having curved faces and their vertices. We can identify, sort, construct, measure, and also can apply a variety of shapes and figures in the geometrical and other problems. We should have the understanding of geometric properties and their relationship. As per shapes, we can classify them, their property and type like angle and type of the triangle (isosceles, obtuse etc.) also we have to know that the same thing can also be done with the help of protractor.
The learning and modeling 2d and 3d objects includes the description of characteristics of 2D shapes and 3D objects and relation between them. We should learn about the description of sides, vertices, faces, and edges of any of the shape in the 2D or 3D geometry. Several two- and three-dimensional games can also be used to understand the concepts regarding the dimension for the purpose of extend knowledge of students' about shapes and to give them hands-on experience working with shapes. Use of such game will help us to become familiar with the names and properties of two- and three-dimensional shapes and their views.
We have to learn about the money exchange problems, date models to read and write (model like Feb. 08, 1988, 06/01/2012 etc.).We should determine the value of equations when there is some missing terms in the operations, also ability to find the missing term in the equation having more than one operation.
In grade V we should also learn about some basic problems like Tools to solve problems, probability to design surveys, collection of data. We should discuss the real world need for some type of data and collection of that data. We should go through the logical reasoning and experiment regarding that collection of data.
