Number Lines for Classroom Wall

Simple techniques have been used to enable gigantic leaps towards understanding and explaining new scientific, mathematical, and technological ideas. The number line was one of the most important “inventions” in mathematics. The Ancient Egyptians could be credited with a highly convenient number line about 2,500 years ago. They tied knots at identical distances along a seam that was employed by counting the number of spots to measure their length.

The credit is commonly attributed to the Englishman John Wallis for designing a number line that shows numbers less than 0. He used a solid 0 line and the positive numerals and a dotted negative line in his earliest illustrations. The usage of number lines showed negative numbers and, more crucially, they were utilized to connect all numbers. Number lines are important because they show how numbers are represented in real life. They were created primarily to allow negative numbers to be expressed in a logical manner as stated before. A subsequent but equally important result was a technique to display all real numbers, including the enigmatic irrational numbers such, –, 2, −2, and so on. As a result, the number line has evolved into a versatile and useful visual tool for teaching kids about numbers. This tool is a major step forward in exploring new mathematical ideas because, by means of employing only one visual model, it was possible to interact with numbers!

There are three basic pieces to a number line. The origin is commonly plotted with zero in the center. This mnemonic can help you recall that the origin is zero: “The origin of most things is nothing.” Negative numbers are displayed to the left of the origin, and positive numbers are plotted to the right. The ends of the horizontal line are marked with arrows to indicate that the line continues to infinity. Number lines can be used to teach simple number addition and subtraction to children. This kind of instruction is beneficial since students can picture the operations and hence learn and understand more rapidly:

Addition using number line: As we all know, adding two positive numbers always results in a positive-sum. As a result, the direction of movement when adding positive numbers is to the right. (For example, (1+4) Equals 5: Locate number 1 on the number line and proceed four steps to the right. After taking four steps from one, you will arrive at the number 5. As a result, the answer is 5. Likewise, when two negative numbers are added together, the result is a negative number. As a result, when adding negative integers, the direction of movement is to the left.

Subtraction using a number line: When subtracting positive numbers, start at the left and work your way to the right, keeping the value of the second number in mind. Subtract 6-3, for example, when the second number is 3 and the first number is 6. Move 3 steps to the left of the number 6 on the number line. The following number is 3, which is the correct answer. To subtract two negative numbers on a number line, start with the first number and move to the right with reference to the value of the second number.

A number line can also be used for multiplication. To accommodate these values, you must draw a larger number line in this scenario. Depending on the numbers being multiplied, you can create a number line by selecting a suitable scale. To multiply 5 by 3, start counting from the origin and move 5 steps three times. In this scenario, 15 is the correct response.

Despite the fact that today’s teachers have a plethora of tools for modeling mathematics, the number line remains an important and helpful math tool. While cubes and other manipulatives help students learn by representing numbers, the number line helps children learn by providing them a different perspective on number relationships. For some ideas, your primary pupils may find utilizing a number line more difficult. It’s crucial to persist with it, though, because number lines allow possibilities to acquire subsequent concepts that cubes can’t, such as negative numbers, decimals, rounding, and graphing.

If you are a mathematics teacher, all these are crucial to the success of your students. That is why we have picked some of the best number line chart designs from amazon for you to choose from. Click on the title of the designs you are interested in, to get to the respective product pages.
