Discovery Education Video. Video discusses irrational numbers such as the number pi because it has no decimal equivalent. Then it discusses how irrational numbers relate to rational numbers. Video is good quality and good for all students as a review or initial learning of the topic.  # Visualizing equivalent fractions | Fractions | Pre-Algebra | Khan Academy

To understand equivalent fractions it helps to see the fractions using something like a grid with shaded and unshaded sections representing the fraction.  # Equivalent fractions and different wholes

## By Khan Academy

Learn how two fractions are equivalent only if they refer to the same whole. For example, 1/2 of a small circle is not the same as 1/2 of a big circle.  # More on equivalent fractions | Fractions | 4th grade | Khan Academy
