Understanding and getting along with the concepts of mathematics requires expertise and practice. Children usually tend to forget the concepts, unless they learn them thoroughly with visualization. Some dedicated learning sites can go a long way in helping the children grab math concepts.
Some Facts About Number Line
While there are numerous aspects and theories regarding mathematical concepts, the number line is one of the earliest contents in mathematics. When you begin learning math, the first thing is to get familiar with the numbers and digits.
A number line is a diagrammatic representation of numbers in mathematics. It comprises a graduated line with a reference set of numbers. The numbers depicted on the line often form a part of the real numbers that have a symbolic representation of R. There are numbers present on both sides of the line. The numbers find their place at fixed distances from each other, The range of the numbers is from negative to positive. A number line can represent numbers like -8 to +8. It helps in a hassle-free learning experience for the children. It can also form a building base for mathematics among children.
Operations Using Number Lines
- Adding Up Numbers- On summing up two or more positive numbers you will get a positive resulting value. If you imagine the addition procedure on a graphical number line, you will see that on adding up 2 and 2, you will get four. The resulting digit will always be on the right side of the number line.
- Adding Up Negative Numbers- Suppose you need to add up some negative numbers like -2 and -4. On adding the two, the resulting number turns out to be negative. On locating the numbers on a number line, you will find it on the left side of the line. It represents the negative direction.
- Subtracting Numbers- If you need to subtract four from eight, the resulting number will be a positive number. The result that comes to four on the number line will fall on the right side of the number line. There might be a case when you need to subtract eight from four. In this case, you will get a negative number. This -4 will lie on the left side of the number line.
- Subtracting Negative Numbers- An innovative thing is there while subtracting negative numbers. Suppose you need to subtract -2 from -6, and it is when you get a resulting number with a positive value. Two digits with negative signs nullify each other to give rise to a positive number. Hence, on subtracting -2 from -6, we will get 4. The resulting digit will remain on the right side of the number line. It will help provide a view of the system of the number line.
Advantages of Using Number Line
A Check on to Reality- The number line gives a real-life experience of the number series. It provides a real-time experience to the children who can get a clear picture of the concepts of the number system. A real-time number analysis in a graphical mode gives clarity to the child’s understanding.
Graphical Model Enhance Memory- There is a science behind the pictorial depiction of the number system. The children find it easier to remember things when it comes to pictures. A graphical representation gives all the details of the positive and negative digits. It becomes easy for the child to point out the positive or negative integer by seeing only a line.
