What Are Number Lines Used for In Math?
There are many ways that make learning and teaching mathematics easier. A number line by far is the most convenient way of simplifying mathematical concepts.
In mathematics, a number line is described as a straight line that has numbers placed at regular intervals. In other words, a horizontal line is segmented with numbers at equal intervals. A number line can be extended in two opposite directions infinitely.
There are a number of ways in which a number line can be utilized in mathematics. We have discussed some of them below:
**COUNTING** - Number lines are used to represent the sequence of the numbers. At this stage, proper segmenting or equal distancing is not of crucial importance. To teach counting the right arrangement and sequencing of numbers matter the most. This method of teaching counting is helpful for young kids. Kids can memorize the number and the right sequence.
**MEASUREMENT** - Number line simplifies another major mathematical concept- measurement. Once kids have grasped the concept of counting, you can focus on developing a number line with equal distances and segmenting. These equal intervals help children in understanding the concepts of measurement. For instance, how many intervals a rolled dice covered.
Through these lessons and worksheets we show students how to use number lines to approach different types of problems.
