What This Standard Means

What Students Need to Do

Students sort collected items or responses into groups using one clear rule. They record the groups with tallies or a T-chart so each item is counted once.

What Mastery Looks Like

Students sort every item by a clear rule and place it in the correct category. They record one tally for each item and confirm that the tallies match the number of items collected.

Common Misconceptions

Students may group the same item in more than one category or leave items out. They may write a numeral instead of one tally per item, or forget to make the fifth tally cross the first four.

How to Assess It

Give students 10 shape cards and a two-column T-chart labeled “circles” and “not circles.” Ask them to sort the cards, record tallies, and explain how they checked the total.

Ways to Teach It

  1. Give pairs a bag of colored counters to sort, then record each color with tallies on a T-chart.

  2. Ask, “Should a striped red button be sorted by color or pattern?” and have students explain which rule they chose.

  3. Play Tally Sort Relay, where teams draw picture cards, place them into categories, and add one correct tally.

  4. Survey classmates about their trip to school, then organize responses such as bus, car, walking, and bicycle in a tally table.
