A Grade 7 class studying Ancient Rome usually contains a student who has read three books about the legions and a student still working out that Rome is a city and an empire. Running one lesson for both without writing four lesson plans is the practical problem. The answer is not four sets of resources. It is one source, one question, and four amounts of support around them.
Differentiate the support, not the content
The common mistake is to give the lower group easier content. A scaffolded student gets a summary of Roman roads while the challenge group gets Tacitus, and by Thursday the two groups are studying different subjects and cannot talk to each other. Alberta's Programs of Study set the same learning outcomes for the whole class, and the sensible reading of that is that everyone works on the same historical question with different support on the way in and the way out.
So fix two things before you differentiate anything: the source everyone works from, and the question everyone answers. Then build four routes to it.
Four routes through one lesson
- Scaffolded. Same source, chunked into three sections with a two-line summary above each, and an answer structured with sentence starters. What is removed is the reading load and the organizational load. The thinking is not removed, because the question is unchanged.
- Core. Full source, six glossary terms in the margin, and an answer frame that names the three things a good response must contain without writing the sentences. Most of the room lives here and it should be real work, not a midpoint.
- Stretch. Full source with no glossary, plus a second short source that partly disagrees. The extra demand is reconciliation, not volume, which is what keeps stretch tasks from becoming more of the same.
- Challenge. Both sources plus a provenance question: who produced this, when, and what were they trying to make a reader believe. Judged on whether provenance is used to weight the evidence rather than mentioned once.
Three of the four routes use the same source sheet, which is where the preparation saving comes from. A unit built with layered materials makes it almost automatic, and The Ancient Romans: Daily Life, Legions & Roads Unit – Worksheets, Projects & Slides (Grades 1–4) is a practical base for the scaffolded and core routes, since the worksheets already come at four levels with the same content behind each.
What the challenge group actually gets
The weakest part of most differentiation is the top. Challenge tasks tend to be longer, not harder, and the strongest students learn that being good at history means writing more.
Three moves fix that on Rome. Give them a historiographical disagreement and ask which interpretation the evidence better supports. Give them a counterfactual with constraints, so the answer is argued from what Romans could and could not do. Or give them a case where the evidence is unusually rich and ask what we still cannot know. The last is the most useful, because it teaches the limits of evidence rather than the accumulation of it. The Cultural Loss of Pompeii and Herculaneum – Advanced History Resource (Grades 11–13) is written above this year group deliberately, and that is why it works as a challenge text: it treats interpretation and loss as the subject.
Bringing four routes back together
Four routes only work if they converge. Reserve the last twelve minutes for a whole-class discussion where every route has something the others need. Ask the scaffolded group for the sequence of events, which they will hold securely because it was structured for them. Ask core for the explanation, stretch for the disagreement between the sources, and challenge for who wanted us to believe what. In that order the discussion builds rather than repeats.
Then set the same exit question for everyone, unscaffolded, so you can see who is transferring. Comparison across civilizations is the fastest check on whether an idea has landed rather than been memorized, and The Ancient Greeks: Olympics, Myths & Daily Life Unit – Worksheets, Projects & Slides (Grades 1–4) gives you parallel material on daily life and civic structures, so a student who understood Roman citizenship can apply the concept somewhere it does not quite fit.
The whole Sunday cost is one source sheet, one question, one glossary strip, one answer frame and one second source, and three of those five get reused every time you differentiate anything. When it runs properly the room looks unremarkable, which is the point: four groups on the same question at four levels of demand, and no student able to tell from the outside which route anyone else is taking.
