Defining and Non-defining attributes can be a vague concept for students. The vocabulary alone is a bit tricky, but getting them to understand why any of it matters can be even trickier. This packet is a tool to help with this common core based standard.
Students practice sorting the attributes of a shape into either a defining or non-defining group. The set includes a color sort, which makes for a good center activity. It also includes lesson ideas and two student worksheet sorts.
