MathScore Practice: Intersection and Union

Description: Find intersection and union of sets.

Adaptive Learning Progression: The sets become bigger.

Sample Levels (out of 3)

Write answers in ascending order, separated by commas. Example: A = {-3, 1, 2, 5 }.

1.	W = {1, 4, 5, 7, 8} X = {3, 4, 8} W ∩ X = {} W ∪ X = {}
2.	J = {} K = {0, 2, 9} J ∩ K = {} J ∪ K = {}

Write answers in ascending order, separated by commas. Example: A = {-3, 1, 2, 5 }.

1.	D = {-5, -2, -1, 1, 3, 5, 7} E is the set of even numbers. D ∩ E = {}
2.	N = {-5, -1, 1, 5, 8} O is the set of positive even numbers. N ∩ O = {}
