ESL and ELL Lesson Plans: Teaching English Learners Without Leaving Them Behind

English language learners are navigating a challenge no native English speaker in your classroom faces: they're trying to learn content and learn the language that content is delivered in simultaneously. It's like taking a chemistry class while also being tested on your French.

The lesson planning challenge for ELL students is real. They need language support without being isolated from academic content. They need time to process in their home language without being excluded from English instruction. They need the same rigorous content as native speakers — just with additional access scaffolds.

Understanding Language Proficiency Levels

ELL instruction starts with knowing where each student is in English language acquisition. Most states use a five-level framework (pre-emergent/emerging/developing/expanding/bridging) or a similar progression. Lesson planning for ELLs requires knowing each student's level.

Emerging (Level 1-2): Students with minimal English rely heavily on visual supports, gestures, and home language. They can communicate in single words and short phrases. Lesson plans should include visual supports for every key concept, home language resources where available, and tasks that allow non-linguistic demonstration of understanding (drawings, sorting, matching).

Developing (Level 3): Students are beginning to communicate in simple sentences and can understand familiar academic content. Lesson plans should include sentence frames, vocabulary scaffolds, partner support, and extended wait time.

Expanding/Bridging (Level 4-5): Students are approaching grade-level language proficiency. They may still struggle with academic vocabulary and complex text structures. Lesson plans should include vocabulary instruction, complex text support strategies, and opportunities to develop academic writing and discussion skills.

Sheltered Instruction: Academic Content With Language Support

Sheltered Instruction (SIOP Model) is the most research-supported framework for planning ELL-inclusive lessons. Its core principle: content objectives and language objectives should appear in every lesson.

Content objective: What students will know or be able to do related to the subject matter. "Students will compare and contrast the cause and effect of photosynthesis."

Language objective: What students will do with language to demonstrate understanding. "Students will write 2-3 sentences comparing two factors using the phrase 'while ___, _____.'"

This distinction is important for planning. Without explicit language objectives, ELL students are expected to develop academic language through osmosis — which doesn't work. With explicit language objectives, you're teaching the language structures students need to access and express content.

Key Lesson Planning Practices for ELL Students

Frontload vocabulary. Before a lesson, pre-teach 3-5 key vocabulary words that ELL students will need to access the content. Brief instruction with visual, example, and non-example is more useful than a full vocabulary lesson. Students who hit an unknown word mid-lesson and stop comprehending miss everything after it.

Provide sentence frames. Oral and written language production is harder than comprehension for emerging ELL students. Sentence frames scaffold production without eliminating challenge: "I think _____ because _____" or "One difference is _____, while _____." Students fill in content; the structure is provided.

Think time before speaking. ELL students process in their home language and translate — this takes longer. Build in processing time before calling on anyone. Think-write-pair-share gives students time to formulate before sharing.

Partner work with language support. Strategic pairing of ELL students with bilingual partners (when available) or with patient, verbal native speakers gives ELL students a model and a processing partner.

Visual representations for everything. Diagrams, concept maps, illustrated vocabulary, demonstrated processes — anything that reduces reliance on auditory English input alone. This benefits ELL students most but helps many others.

Home language as a resource, not a problem. When students use their home language to process complex content before expressing in English, they're demonstrating content understanding — the goal. Bilingual discussion, bilingual notes, and home-language texts (where available) support content learning while English proficiency develops.

Content Teachers vs. ESL Specialists

Most ELL students spend the majority of their school day in general education classrooms, not ESL pull-out. This means content teachers are doing ELL instruction whether they've had training in it or not.

Lesson planning for content teachers with ELL students:

• Know your students' proficiency levels and what those levels mean for language production
• Build visual supports into your standard lesson materials
• Plan your language objective alongside your content objective
• Brief any pull-out ESL support on what's happening in your class so they can reinforce it

The collaboration between content teacher and ESL specialist can be one of the most powerful supports an ELL student receives — when it's planned for, not incidental.

Assessment of ELL Students

ELL students are often assessed in ways that conflate language proficiency with content knowledge. A student who knows the content but can't yet express it in English may appear to not know the content.

Lesson plans should include assessment approaches that separate language from content where appropriate:

• Allow verbal responses to written questions (student speaks, teacher or partner scribes)
• Accept diagrams, visual representations, or home-language drafts as evidence of understanding
• Use performance tasks where students demonstrate understanding through action, not only through academic language

The question is always: do I know whether this student understands the content, or do I only know whether they can express it in academic English? These are different things, and conflating them produces inaccurate data and lower expectations.
