What This Standard Means
What Students Need to Do
- Students look at objects that have already been sorted and identify the attribute used. They describe and label each group by color, size, shape, or another visible feature.
What Mastery Looks Like
- A student identifies the attribute used to sort a set, such as color, size, or shape. The student gives each group a clear label that matches the same attribute.
Common Misconceptions
- Students may name the objects instead of the attribute used to sort them. They may also label groups inconsistently, such as calling one group red and another group circles.
How to Assess It
- Show three groups of buttons sorted by size. Ask, “How were these buttons sorted, and what label belongs on each group?”
