Math Practice Topic: 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 = {}
WX = {}
2.
J = {}     K = {0, 2, 9}

J  ∩ K = {}
JK = {}

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 = {}
