This card sort activity has students categorize 24 statements about the Real Number System as Always True, Sometimes True, and Never True. The statements relate to the different types of numbers in the Real Number System: Real, Irrational, Rational, Integer, Whole, and Natural. 8.2A Extend previous knowledge of sets and subsets using a visual representation to describe relationships between sets of real numbers
A Venn diagram represents the sets and subsets of different types of triangles. For example, the set of acute triangles contains the subset of equilateral triangles, because all equilateral triangles are acute. The set of isosceles triangles partly overlaps with that of acute triangles, because some, but not all, isosceles triangles are acute.
Sets and subsets
Students are presented with multiple opportunities and approaches to practice classifying and analyzing the relationship between sets and subsets of real numbers in this 3 page activity.
