What This Standard Means
What Students Need to Do
- Students choose one visible feature, such as color, shape, or size, and use it to group a small collection. They count each group and arrange the groups from fewest to most.
What Mastery Looks Like
- A student sorts every item once and explains the rule used. The student counts each group accurately and places the groups in order by total, including groups with equal totals.
Common Misconceptions
- Students may switch from color to size while sorting, or leave out an object that differs in several ways. They may compare object sizes instead of group totals, or think tied groups cannot share a position.
How to Assess It
- Give each student eight counters: one red, three blue, and four yellow. Say, “Sort them by color, count each group, then arrange the groups from fewest to most.”

Ways to Teach It
Give pairs ten attribute blocks to sort by one chosen feature, label each group, count it, and arrange groups from fewest to most.
Ask, “Could the same buttons be sorted a different way?” Have students name a new rule and predict how the groups would change.
Play Sort and Race: students draw picture cards, place each by category, then race to order category cards by their final counts.
Sort classroom supplies into pencils, crayons, and markers, count each bin, and decide which supply has the fewest and most items.
