A four-question exit slip on 3rd grade fraction basics, sized for the last minutes of a lesson. Students write the fractions shown by a circle with 3 of 4 slices shaded and a bar with 1 of 6 sections shaded, complete two statements about a strip folded into 8 equal parts, work through Leo's cornbread (6 equal pieces, 2 eaten), and say what the denominator 4 in 3/4 reveals about the whole. The key accepts 2/6 or 1/3 for Leo.
3.NF.1
“Understand a fraction 1/b as the quantity formed by 1 part when a whole is partitioned into b equal parts; understand a fraction a/b as the quantity formed by a parts of size 1/b.”
All four questions build the a/b idea: unit fractions in questions 1 to 3, and question 4 makes the denominator's meaning explicit (4 equal parts in the whole).
Question 1 pairs a circle showing 3/4 with a six-section bar showing 1/6. Students write each fraction on a labeled line.
Two fill-in blanks describe a paper strip folded into 8 equal parts: one part equals 1/8 of the strip, and shading 5 parts gives 5/8.
Question 3 asks for one piece (1/6) and the eaten amount (2/6) of a pan sliced into 6 equal pieces. Question 4 closes with what the bottom number of 3/4 tells you.
Exit ticket
Hand it out five minutes before the bell after your first fraction-notation lesson. Four questions fit the time and still separate part-counting from fraction-writing.
Next-day grouping
Sort slips overnight by question 4. Students who describe the denominator as "the big number" rather than the count of equal parts form your reteach table.
Sub-plan check
Leave it with a substitute as evidence of the day's lesson. The answer key is short and unambiguous, so any adult can score it.
