select a place on the number line to plot the point.

Since this is a mixed number, it consists of a hole number and a fraction. So, the whole number is 1. So, the point goes AT LEAST to number 1.

Now, as you can see, the number line is divided between the whole numbers by 2 lines in between each whole number. Those 2 lines divide the space up into thirds. So, the space in between each line is a third. 

So, go to the one, and then move forward one dash. And that is one third

So, the line after the 1 is 1 and one third
