I am sure that most of us have encountered number line during our primary or secondary school in Mathematics class. Basically, number line is useful for children to do an addiction or subtraction problem.
Addition Problem
This picture explains us how to do 5 = 4 using number line. First, start counting five from zero (0) and you will reach at number 5. Then jump four number afterward and you will reach at number 9.
Subtraction Problem
This picture meanwhile explain us how to do 6-2 using number line. First, start at number 6 and move backwards 4 until you reach number 2. The gap between 6 and 2 is the answer which is 4.
Getting Children to Use a Number Line
Use ruler as a tool to represent number line. This is effective for less than ten problem.
Or else, use bigger number ruler like this one. Or else, just use pencil and paper! Draw a line horizontally, and start your number.
