Saying What Is the Same and What Is Different

Purpose

Teachers: once the topics are supported on both sides, students need a controlled comparison-language set to say similarities and differences accurately. This lesson introduces a small, high-utility connector set with an explicit clause-structure card and moves through controlled practice (one structure at a time), guided practice (teacher-modeled category transformed three ways), and free practice (students write four independent sentences on four different supported topics). Comparative adjectives (-er and more … than) are introduced only where they express a meaningful difference the evidence supports — no giant grammar dump.

Grammar target

For a supported topic with evidence from both cases from CP-01, write a comparison sentence with one of the two core structures: both … and for a similarity, but for a difference. (Optional Level 3–4 stretch only, never required: whereas, unlike, while, however, in contrast, comparative -er/more … than.)

Essential question

How do I say similarities and differences between two cases without over-claiming what the evidence shows?

Objective

Students can produce grammatically accurate comparison sentences using the two core structures — both … and for a similarity and but for a difference — with correct clause structure and punctuation; whereas, unlike, and comparatives remain optional Level 3–4 stretch.
