Four Activities for Reviewing Number Sets with Your Students
Understanding the different number sets and how they relate to each other is crucial to developing structured, logical mathematical thinking. For a dynamic approach to these concepts in the classroom, try these ideas:
- Have your students watch the Alloprof video on number sets (French only) in class or as part of a flipped classroom approach.
- Have your students take a quiz where they have to match number sets to their different properties.
- Put together a “true or false” quiz with examples of numbers belonging to different number sets. For example, “3/4 is a natural number. True or false?”
- Draw a table with the columns ℕ, ℤ, ℚ, ℚ' (or ℝ\ ℚ) and ℝ and pass out sticky notes with different numbers to your students. Then, divide the class into teams and organize a relay race with the goal of putting the numbers in the right columns as quickly as possible.
