Exploring Fractions on a Number Line

This video tutorial teaches how to find and represent fractions on a number line. It begins with an introduction to key vocabulary such as fractions, numerators, and denominators. The tutorial then explains how fractions are positioned between whole numbers on a number line, using examples to illustrate the process of identifying fractions. The video includes practice exercises to reinforce the concepts, guiding students through counting spaces to determine numerators and denominators. Advanced practice is provided with multiple points on a number line, emphasizing the importance of counting spaces rather than tick marks.
