SIOP Lesson Plan: How to Write One (with Template and Example)

Estimated reading time: 7 minutes

A SIOP lesson plan is a lesson built on the Sheltered Instruction Observation Protocol, designed so English Learners learn grade-level content and academic English at the same time. Its defining feature is simple: every plan states both a content objective and a language objective, then uses the eight SIOP components to make the content comprehensible. This guide explains how to write a SIOP lesson plan step by step, with a template and a worked example.

What Is a SIOP Lesson Plan?

Quick answer: a SIOP lesson plan is a content lesson organized around the SIOP model, with a stated content objective and language objective and deliberate attention to making the language accessible. Unlike a standard plan, it never assumes English Learners will pick up the academic language on their own; it plans for it explicitly.

The plan is not a separate curriculum. It is your existing content lesson, redesigned so the language demands are visible and supported. Any content teacher can write one.

The Two Objectives Every SIOP Plan Needs

Writing the language objective is the step teachers most often skip, and it is the one that makes a plan a SIOP plan. It forces you to identify the vocabulary and sentence structures English Learners need before the lesson, not during it.

How to Write a SIOP Lesson Plan: A Process

1. Start with the content objective. What will students know or be able to do by the end?
2. Add a language objective. What language (vocabulary, sentence structures, or a function like compare or explain) will they use to reach it?
3. Build background. Plan how to connect to prior knowledge and pre-teach key vocabulary.
4. Plan comprehensible input. Choose the visuals, models, and scaffolds that make the content understandable.
5. Design interaction. Build in structured student talk (pairs, groups, sentence frames) so every student produces the language.
6. Plan practice and application. Give a hands-on task that uses the new content and language.
7. Plan review and assessment. Decide how you will review vocabulary and check that objectives were met.

A Simple SIOP Lesson Plan Template

A Worked Example

A middle-school science lesson on ecosystems might read: Content objective, students explain how energy flows through a food chain; language objective, students describe the flow using cause-and-effect language (because, therefore, as a result). The teacher pre-teaches producer, consumer, and decomposer with images; models a food chain; gives partners a sentence frame (“The ___ gets energy from the ___ because ___”) to explain a chain aloud; then has students build and narrate their own. The interaction step is where the language objective actually gets practiced, and where the plan lives or dies.

Common Mistakes to Avoid

1. Skipping the language objective. Without it, the plan is just a regular content lesson.
2. Vague language objectives. “Use vocabulary” is too broad; name the words or structure.
3. Planning input but not output. Making content understandable without planning for students to produce language.
4. Under-planning interaction. Leaving student talk to chance, so the lowest-proficiency students stay silent.

District Benchmark

Translate it. Asking every content teacher in a district to write a language objective and a structured interaction task for each lesson is a real shift, but it is teachable and coachable. The limiting factor is not the plan; it is delivering the interaction step to every English Learner. A strong plan defines the talk; the capacity to let each student actually do the talking is the harder half, and where scalable practice pays off.

A Fuller Worked Example

Take an elementary literacy lesson on main idea. The content objective: students identify the main idea of a paragraph and two supporting details. The language objective: students state the main idea using the frame “The main idea is ___ because ___.” The teacher pre-teaches main idea, detail, and support with a visual; models with a shared text; has partners identify the main idea aloud using the frame; then students write their own. Each of the eight components has a place, and the language objective is what makes the interaction step do real work.

Adapting the Template Across Subjects

The same template travels. In math, the language objective might target explaining a process with sequence words; in science, describing cause and effect; in social studies, comparing and contrasting. What changes is the language function the objective names; what stays constant is the pairing of a content goal with a language goal and a planned way for students to produce that language. This is why a single SIOP planning routine can serve every content area.

Reviewing a Plan Before Teaching

Before teaching, a quick self-check catches most weak plans: Is there a specific language objective, not just a content objective? Is there a planned moment where every student produces the target language, not only a few volunteers? Are the scaffolds (visuals, frames, models) actually in the plan? A plan that passes these three checks will deliver the interaction that English Learners need; one that fails them usually becomes a content lesson with English Learners left behind.

Planning SIOP Lessons as a Team

SIOP planning is stronger and more sustainable when teachers do it together. Common planning time lets content and EL teachers co-write language objectives, share scaffolds, and align on the academic vocabulary a unit demands. A content teacher knows the subject; an EL specialist knows how to make its language accessible, and the plan improves when both contribute. Districts that build SIOP planning into collaborative team time, rather than leaving it to individual teachers after hours, see more consistent quality and less burnout. The plan becomes a shared asset that can be reused and refined, not a solo task repeated from scratch each week.

Making SIOP Planning Sustainable

The honest objection to SIOP lesson planning is time: writing a language objective and a structured interaction task for every lesson is real work. The answer is to build a bank rather than start over each time. Once a teacher has language objectives and scaffolds for a recurring lesson type, such as explaining a process or comparing two things, those components can be reused across units with light adaptation. Templates, shared drives of objectives, and a small set of go-to interaction structures turn SIOP from an unsustainable nightly chore into a repeatable routine. Sustainability, not enthusiasm, is what keeps the practice alive past the first semester.

Differentiating a SIOP Plan for Mixed Levels

A single classroom often holds English Learners at very different proficiency levels, from newcomers to students near reclassification, alongside native English speakers. One SIOP lesson plan can serve them all, but only if it builds in differentiation. The content objective usually stays the same for everyone; the language objective and the supports flex by level. A newcomer might use a heavily scaffolded sentence frame and a home-language bridge to state the main idea, while a more advanced English Learner produces a full explanation with academic connectors, and a native speaker extends the idea in writing. The plan anticipates these tiers rather than improvising them mid-lesson.

Practical differentiation moves in a SIOP plan include tiered sentence frames (from fill-in-the-blank to open-ended), varied output expectations (a labeled diagram versus a written paragraph), strategic grouping that pairs proficiency levels for peer support, and leveled scaffolds such as word banks or visuals available to those who need them. The goal is not four separate lessons but one lesson with planned entry points, so every student engages the same content at a language level they can access. This is where the language objective earns its keep: by naming the target language explicitly, it lets a teacher scale the support up or down without lowering the intellectual demand of the content. Planning differentiation in advance is what keeps the interaction step working for a genuinely mixed class rather than only for the middle.

Frequently Asked Questions

What is a SIOP lesson plan?

A content lesson built on the SIOP model, with a stated content objective and language objective and deliberate supports (comprehensible input, scaffolds, structured interaction) that make the content accessible to English Learners.

What are the two objectives in a SIOP lesson?

A content objective (the subject-area goal) and a language objective (the specific language students will use to reach it). Both are stated for every lesson.

What components go into a SIOP lesson plan?

The eight SIOP components: lesson preparation (objectives), building background, comprehensible input, strategies, interaction, practice and application, lesson delivery, and review and assessment.

Who writes SIOP lesson plans?

Any teacher of English Learners, in any subject, not just EL specialists, because English Learners learn English across all content areas.

Conclusion

A SIOP lesson plan is your content lesson, redesigned so the language demands are visible and supported: two objectives, comprehensible input, and structured interaction. Writing one is a teachable skill for any content teacher. The step that determines results is interaction, getting every English Learner to produce the target language, which is exactly the part a full classroom struggles to deliver and the part worth resourcing.

The Interaction Step Is Where Plans Break Down

A SIOP plan can be flawless on paper and still stall at the same place: the interaction step. You have written a precise language objective and a sentence frame, but when the moment comes for every student to produce that language, only the confident few actually do. The plan called for talk from all; the period delivers talk from some.

This is a bandwidth problem, not a planning one. One teacher listening and responding can be present for a single conversation at a time, so most students rehearse the frame silently or not at all while the teacher works the room. The objective was sound; the individual practice it requires is what the class period cannot multiply.

So districts are looking for ways to give every student the reps the plan assumes. Telo AI is one example, providing adaptive conversational practice on a lesson’s language objective in English and, for bilingual programs, through separate Spanish and French apps.

When the planned talk actually happens for everyone, the language objective stops being aspirational and starts showing up in student output. A SIOP plan is only as strong as the interaction it manages to deliver, and that delivery is the half worth building capacity around.
