How Do You Find a Union and Intersection from a Venn Diagram?
Is there a difference between the union of sets and the intersection of sets? The teacher uses a Venn diagram to illustrate how to determine what makes a union and what makes an intersection of sets.
Curated OER
How Do You Find the Domain and Range of a Relation?
A straightforward explanation of domain and range. The domain of a set of coordinates are the X-values, and then range are the Y-values of the set.
Curated OER
What is a Relation?
A very short explanation of what makes a relation: a set of ordered pairs.

The Union of Sets
The union of two or more sets is well defined in this two-and-a-half-minute video. A clear definition is provided alongside a concrete example, which makes for good teaching.
Curated OER
What's a Venn Diagram, and How Do You Find the Intersection and Union of a Set?
A straightforward illustration of a Venn diagram. Intersection is what they sets have in common, and the union is all the elements of the sets. The diagram certainly helps you see what this means.

How Do You Name a Set That's Graphed on a Number Line?
Identify the numbers on a number line that are represented by a dot. Then write the numbers in a bracket set starting on the left and moving to the right.
Curated OER
How Do You Graph a Set on a Number Line?
Graph a set of numbers on a number line by placing a dot on the number line to represent each number in the given set.
