Six Tablets, Twenty-Four Students, Forty-Seven Minutes
Mr. Delgado teaches Algebra I to four sections of 24 students in a 47-minute period. His room has six district tablets in a charging cart and a projector; personal phones are permitted for instruction under campus policy. On the last unit, exit tickets averaged 82% correct, but the unit test averaged 61%, with the largest losses on multi-step word problems requiring students to set up an equation from a context. He wants to run station rotation on the next unit's practice days, but the math coach warns that with six devices, two-thirds of the class will be off task. One student has an IEP requiring text-to-speech and extended time on assessments.
1. Design the rotation and answer the coach's objection with specifics.

The coach is right about the arithmetic and wrong about the conclusion: with six tablets you cannot put 24 students on devices, so stop trying. Run four stations of six, about 10 minutes each, with only one station device-dependent. A (tablets): an interactive graphing or modeling tool where students build an equation from a context and watch the graph respond. B (no tech): a card sort separating 'given,' 'unknown,' and 'relationship.' C (teacher-led): two worked examples with faded scaffolds, targeting setup, which is where the test losses were. D (paper): annotate an incorrect solution and name the error. Off-task behavior drops when every station has a product to hand in and a visible timer, and when the teacher is not the only source of help. Personal phones may substitute at station A only if policy and the tool permit; test the tool on both form factors before Monday rather than mid-lesson.
2. The 82% exit-ticket average against a 61% test average is the central data point. What does it mean and what should change?

The gap is a signal about the assessment, not only the students. Exit tickets most likely measured procedural execution ('solve this equation'), while the test measured modeling: choose a variable, write a relationship, then solve. Those are different constructs, so the formative data was never predicting the summative. Two moves follow. First, rewrite exit tickets so at least one item per day is a setup item in a novel context, scored with a short rubric (identifies quantities, defines the variable, writes the relationship, solves), so the daily data tracks the standard actually being tested. Second, use the rotation as the intervention and keep a two-item setup check as a weekly progress monitor for students below 60%. Also separate 'cannot set up' from 'sets up but makes arithmetic errors' - the first needs modeling practice, the second needs accuracy practice, and a single class average hides which problem you have.
3. How do you build the IEP accommodations into the station design rather than bolting them on?

Design them in. If text-to-speech is required, the device station should carry the heaviest reading load, and that student's rotation should place it early in the period while the teacher is free to check in. Verify the specific tools: many math and reading tools have built-in speech, but a PDF scanned as an image reads as silence, so pre-check every document for selectable text before the lesson. At the paper stations, supply a read-aloud or digital version of the word problems, and allow an oral response at the teacher station if writing is the barrier rather than algebra. Extended time applies to anything graded for accuracy, so decide before the unit whether that means fewer items measuring the same constructs or a carry-over into the next day. Settle that with the IEP case manager during planning, not on the morning of the assessment.
