This Warm-up prompts students to compare four strings of numbers. To identify which 3 go together, students may use what they know about properties and kinds of numbers—factors and multiples, odd and even numbers, numbers in base-ten, and so on. It gives students a reason to use language precisely (MP6). It gives the teacher an opportunity to hear how students use terminology to talk about the characteristics of the items in comparison to each other.
In the discussion, it is important to talk about what the writer had to pay attention to when they designed this activity. This understanding will prepare students for a series of design activities that lead to an opportunity to create their own Which Three Go Together?
