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
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.
