Three same-sized loaves are shared equally among four people. How much does each person receive?
Look for: 3/4 loaf per person.
If you observe: Writes 4/3 by reversing recipients and loaves.
Respond: Cut each loaf into four equal pieces and distribute one piece from each loaf to each of four person spaces.
Four loaves are shared among three people. Must each person get less than one loaf?
Look for: No. Each gets 4/3 or 1 1/3 loaves.
If you observe: Assumes every fraction or share is less than one.
Respond: Give each person one whole loaf first, then share the remaining loaf into thirds.
Check independently: Share two loaves equally among three people and check one share.
Each gets 2/3 loaf; 3 × 2/3 = 2 loaves.
Use the unit fraction sharing short intervention if the difficulty persists. Return to this check before repeating the exit ticket.
e1 meets its criterion: e1 gives 3/4 for 3 ÷ 4. e2 also meets its criterion: e2 says the denominator counts equal shares or people in the sharing story.
Continue to the linked next lesson. Compare sharing several wholes with sharing a unit-fraction amount among people.
Next lesson: Unit Fraction Sharinge1 does not yet meet this criterion: e1 gives 3/4 for 3 ÷ 4.
Ask the learner to explain the attempt, then use the matching diagnostic probe to identify the difficulty. Work through the focused reteach below and its check. Use the linked short intervention if the difficulty persists; retry e1 and e2 before moving on.
Open the linked short interventione1 meets its criterion, but e2 does not yet show this evidence: e2 says the denominator counts equal shares or people in the sharing story.
Use the sharing intervention to emphasize equal recipients, then return to three whole loaves and have the learner label the four people represented by the denominator.
Open the linked short interventionUse these as follow-up prompts, then examine the learner’s model or explanation. Open responses may differ from the sample while satisfying the criteria.
Watch for: Reverses wholes and recipients in an equal-sharing quotient.
Try: Draw three loaves and four recipient spaces. Cut every loaf into fourths and give one fourth from each loaf to every person. Each receives 3/4 loaf; four shares recover the original three loaves.
