Students sort completed evidence cards from earlier phases into categories such as whole-number division, decimal division, fraction division, and rate comparisons. Using chart paper, teams highlight patterns in quotients, note where partial quotients or equivalent ratios were more efficient, and flag any answer that seems inconsistent with estimates or context. Each team creates one comparison chart with at least two models side by side and short notebook captions naming the strategy used.

# What teachers do
1 [Facilitator] Launch the task by posting the essential question and briefly naming the four sort categories: whole-number division, decimal division, fraction division, and rate comparisons. Model one evidence card by thinking aloud about the context, estimating a reasonable quotient, and deciding which model or strategy best fits. (7 min)
2 [Facilitator] Place students in teams and distribute evidence cards, category headers, a pattern chart organizer, sticky flags, and chart paper. Ask teams to complete a first sort, grouping cards by problem type and setting aside any card they are unsure about for later discussion. (10 min)
3 [Facilitator] Guide teams to do a second sort inside each category by strategy or model, such as partial quotients, equivalent ratios, open arrays, ratio tables, or division notation. Prompt students to compare two cards side by side, discuss which strategy seems more efficient, and use estimates to flag any answer that does not fit the pantry context. (12 min)
4 [Facilitator] Have each team create one comparison chart on chart paper that shows at least two models side by side and includes pattern notes about quotient size, place-value shifts, or fraction-as-division ideas. Remind students to label the models clearly and connect their comparisons to fair pantry-sharing decisions. (10 min)
5 [Facilitator] Close with a brief share-out and notebook reflection. Invite teams to name one pattern they found and one card they revised, then have each student write a short caption that names one model, the strategy used, and how it helped compare quantities or notice an error. (6 min)
Preparation (7 items)
  • Prepare mixed evidence card sets from earlier work, making sure each set includes whole-number division, decimal division to hundredths, fraction division involving unit fractions and whole numbers, and at least one rate comparison tied to pantry inventory or package sizes.
  • Create and print category headers for whole-number division, decimal division, fraction division, and rate comparisons, plus a small 'not sure yet' card for teams that need to revisit a choice.
  • Prepare a simple team pattern chart organizer with spaces for category, estimate, strategy/model used, pattern noticed, and reasonableness check.
  • Gather chart paper, markers, sticky notes, and small flag stickers so teams can mark answers they think are inconsistent with estimates or the pantry context.
  • Select one sample evidence card for the opening model and plan a short think-aloud that shows estimating first, sorting by problem type, and naming a matching strategy such as partial quotients or an open array.
  • Write sentence starters on the board or provide table tents, such as 'We sorted this card here because...', 'Our estimate was...', 'This strategy was efficient because...', and 'This answer seems unreasonable because...'.
  • Prepare supports for varied reading levels by enlarging key cards, underlining important numbers and units, and adding brief vocabulary supports for terms such as quotient, equivalent ratio, and reasonableness.
Student-facing instructions
You will work with your team to sort pantry evidence cards from earlier investigations into four categories: whole-number division, decimal division, fraction division, and rate comparisons. Your materials are evidence cards, category headers, a pattern chart organizer, sticky flags, chart paper, markers, and your math notebook. First, sort the cards by problem type. Next, look inside each category and compare the strategies or models shown, such as partial quotients, equivalent ratios, open arrays, ratio tables, or division notation. Estimate before you decide whether an answer makes sense, and flag any card that seems inconsistent with the numbers or the pantry-sharing context. Then create one team comparison chart with at least two models side by side, label the strategy used, and add short notes about patterns you notice. Finally, write a notebook caption that names one model, the strategy you chose, and how it helped you compare quantities or check reasonableness.
