Finding Missing Numbers on a Number Line

This video tutorial by Mr. J explains how to find missing numbers on a number line. It covers the basic concepts of positive and negative numbers, and how moving right or left on the line affects value. Through four examples, the video demonstrates counting by different intervals, including one, five, and two, to fill in missing numbers. The tutorial emphasizes understanding the distance between numbers and applying it to find missing values, even when numbers are not consecutive.
