Sets and subsets

### Rational Numbers Graphic Organizer and Game

My students really struggle with rational numbers so I came up with a lesson to help them understand rational numbers visually and using hands-on. My students really enjoyed this activity because it helps my visual and hands-on learners. Students use a number line to see the sets and subsets of rational numbers and use colors to separate the sets and subsets.

### The Real Number System - Always, Sometimes, or Never Card Sort

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

TEKS 6.2A 7.2 8.2A Blank Venn Diagram for students to practice relationships between sets and subsets of real numbers. 2 per page and 1 answer key

### Sets and Subsets of Real Numbers

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.

### Number Sense Matching Activity

Students use this matching activity to identify sets and subsets of real numbers, including rational, irrational, integer, whole and natural sets of numbers. Students match definitions, words, and numbers, including a cut and paste activity for the graphic representations of sets.

### Coloring Sheet- TEKS 8.2 Review Comparing, ordering real numbers, square roots)

This is a fun way to practice a skill. It can be done with a partner or individually.8.2 The student applies mathematical process standards to represent and use real numbers in a variety of forms.-Extend previous knowledge of sets and subsets using a visual representation to describe relationships between sets of real numbers-Approximate the value of an irrational number, including pi and square roots of numbers less than 225, and locate that rational number approximation on a number…

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.
