The Fraction Quilt and the Identical Square Problem
Mr. Patel, a fourth-grade classroom teacher, and Ms. Rivera, the art teacher, plan a six-session integrated unit on fractions and quilting. There are 24 students; each session is 40 minutes; the art budget is $60. Mr. Patel wants every student to produce an identical 4x4 paper quilt square with a specified pattern so the hallway display forms a precise grid and the math assessment is consistent. Ms. Rivera wants students to choose their own patterns within constraints. The first planning meeting ends with tension. The principal has asked for documentation that the unit addresses both math and visual arts standards. Ms. Rivera also has a student with a fine-motor IEP goal and two English learners. The hallway display is scheduled for parent-teacher conferences in four weeks.
1. Design a unit structure that meets Mr. Patel's need for comparable math evidence and Ms. Rivera's commitment to student choice.
Read the worked answer
The teachers can keep a common task structure while allowing choice inside it. Every student uses the same 4x4 grid and the same required math constraints: for example, one-half of the squares in one color family, one-fourth in a second, one-eighth in a third, and the remaining eighth in a fourth; at least one line of symmetry; and a written fraction sentence explaining the composition. Within those constraints, students choose colors, motifs, and the placement that satisfies the symmetry rule. Comparability comes from the shared constraints and a common rubric, not from identical patterns. The hallway display can still form a precise grid if every square is the same outside dimension and border width. Mr. Patel can assess fraction equivalence and part-whole reasoning; Ms. Rivera can assess composition, contrast, and craft. A short pre- and post-assessment plus a student reflection gives both teachers evidence without forcing uniformity.
2. How should the teachers plan for the student with fine-motor IEP goals, the English learners, and the $60 budget?

They should build access into the task rather than adding it after the first session. For the student with fine-motor goals, provide precut 4x4 templates, larger squares, adaptive scissors, glue sticks instead of liquid glue, and the option to arrange shapes before pasting. The IEP goal can be addressed through controlled cutting and placement, not by lowering the math expectation. For the English learners, use a visual word wall with fraction terms and quilt vocabulary, sentence frames such as 'My quilt has ___ out of ___ squares in ___ color,' and paired planning time. The $60 budget is enough for colored paper, glue sticks, and a few shared tools if the teachers use donated or classroom supplies and avoid fabric. They should not spend the budget on individual kits. A six-session sequence should include one session for planning and vocabulary, three for making, one for revision, and one for gallery walk and reflection. This pacing protects the students who need more processing time.
3. What documentation should they submit to the principal to show both math and art standards are addressed?
Read the worked answer
The documentation should be a short standards map, not a folder of everything. It can list each session, the math standard addressed, the visual art standard addressed, and the evidence collected. For math, include the pre- and post-assessment, a sample fraction sentence, and a photo of the grid display with a key. For art, include the rubric criteria for composition, color contrast, craft, and reflection, plus two or three student statements explaining their choices. The teachers should also note the differentiation for the IEP goal and the English learners, since the principal asked about the unit rather than only the display. A brief narrative can explain why the squares are not identical: common constraints create comparable evidence, while choice supports artistic decision-making. Finally, include a student reflection prompt and a few anonymized responses. This documentation shows alignment and learning without claiming that the display alone proves either subject was taught well.
