6. Integers Class 6 Extra Questions CBSE Notes for Integers Class 6 Extra Questions

● We have seen that there are times when we need to use numbers with a negative sign. This is when we want to go below zero on the number line. These are called

negative numbers. Some examples of their use can be in temperature scale, water level in lake or river, level of oil in tank, etc. They are also used to denote debit account or outstanding dues. ● The collection of numbers…, – 4, – 3, – 2, – 1, 0, 1, 2, 3, 4, … is called integers. So, – 1, – 2, – 3, – 4, … called negative numbers are negative integers and 1, 2, 3, 4, … called positive numbers are the positive integers. ● We have also seen how one more than given number gives a successor and one less than a given number gives predecessor.

8. Decimals Class 6 Extra Questions CBSE Notes for Decimals Class 6 Extra Questions

● To understand the parts of one whole (i.e. a unit) we represent a unit by a block. One block divided into 10 equal parts means each part is 1 10 (one-tenth) of a unit. It can be written as 0.1 in decimal notation. The dot represents the decimal point and it comes between the units place and the tenths place. ● Every fraction with denominator 10 can be written in decimal notation and vice-versa. ● One block divided into 100 equal parts means each part is ( ) 1 100 (one-hundredth) of a unit. It can be written as 0.01 in decimal notation. ● Every fraction with denominator 100 can be written in decimal notation and vice-versa. ● In the place value table, as we go from left to the right, the multiplying factor becomes 1 10 of the previous factor. Please refer ​Decimals Class 6 Extra Questions for more information.

10.Mensuration Class 6 Extra Questions CBSE Notes for Mensuration Class 6 Extra Questions

● When we talk about some plane figures as shown below we think of their regions and their boundaries. We need some measures to compare them. We look into these now. ● You can make them with a wire or a string. If you start from the point S in each case and move along the line segments then you again reach the point S. You have made a complete round of ● The distance covered is equal to the length of wire used to draw the figure. This distance is known as the perimeter of the closed figure. It is the length of the wire needed to form the figures. The idea of perimeter is widely used in our daily life. ● A farmer who wants to fence his field. ● An engineer who plans to build a compound wall on all sides of a house. ● A person preparing a track to conduct sports. Please refer M ​ ensuration Class 6 Extra Questions​ for more information.

11. Algebra Class 6 Extra Questions CBSE Notes for Algebra Class 6 Extra Questions

● We looked at patterns of making letters and other shapes using matchsticks. We learnt how to write the general relation between the number of matchsticks required for repeating a given shape. The number of times a given shape is repeated varies; it takes on values 1,2,3,…. It is a variable, denoted by some letter like n. ● A variable takes on different values, its value is not fixed. The length of a square can have any value. It is a variable. But the number of angles of a triangle has a fixed

value 3. It is not a variable. 3. We may use any letter n, l, m, p, x, y, z, etc. to show a variable. ● A variable allows us to express relations in any practical situation. ● Variables are numbers, although their value is not fixed. We can do the operations of addition, subtraction, multiplication, and division on them just as in the case of fixed numbers. Please refer A ​ lgebra Class 6 Extra Questions​ for more information.

12. Ratio and Proportion Class 6 Extra Questions CBSE Notes for Ratio and Proportion Class 6 Extra Questions

● For comparing quantities of the same type, we commonly use the method of taking difference between the quantities. ● In many situations, a more meaningful comparison between quantities is made by using division, i.e. by seeing how many times one quantity is to the other quantity.

This method is known as comparison by ratio. For example, Isha’s weight is 25 kg and her father’s weight is 75 kg. We say that Isha’s father’s weight and Isha’s weight are in the ratio 3 : 1. ● For comparison by ratio, the two quantities must be in the same unit. If they are not, they should be expressed in the same unit before the ratio is taken. ● The same ratio may occur in different situations. ● Note that the ratio 3: 2 is different from 2 : 3. Thus, the order in which quantities are taken to express their ratio is important. Please refer R ​ atio and Proportion Class 6

13. Symmetry Class 6 Extra Questions CBSE Notes for Symmetry Class 6 Extra Questions Symmetry is quite a common term used in day to day life. When we see certain figures with evenly balanced proportions, we say, “They are symmetrical”.

1.Tajmahal (U.P)

2. Thiruvannamalai (Tamil Nadu)

These pictures of architectural marvel are beautiful because of their symmetry. Suppose we could fold a picture in half such that the left and right halves match exactly then the picture is said to have line symmetry (Fig 13.1). We can see that the two halves are mirror images of each other. If we place a mirror on the fold then the image of one side of the picture will fall exactly on the other side of the picture. When it happens, the fold, which is the mirror line, is a line of symmetry (or an axis of symmetry) for the picture. Please refer S ​ ymmetry Class 6 Extra Questions​ for more information.

14. Practical Geometry Class 6 Extra Questions CBSE Notes for Practical Geometry Class 6 Extra Questions

● This chapter deals with methods of drawing geometrical shapes. 1. We use the following mathematical instruments to construct shapes: ● A graduated ruler ● The compasses ● The divider ● Set-squares ● The protractor

● Using the ruler and compasses, the following constructions can be made: ● A circle, when the length of its radius is known. ●

A line segment, if its length is given.

● A copy of a line segment. ● A perpendicular to a line through a point (a) on the line (b) not on the line. Please refer P ​ ractical Geometry Class 6 Extra Questions​ for more information.
