+
+Seiten 87–88 (Teil 2 Grammatik) · Lösungen S. 113 · Übungen L1–L2
+
+## Overview
+
+- Skill focus: Grammatik (personal pronouns as Akkusativ/Dativ objects,
+  demonstrative pronouns replacing nouns)
+- Topic: matching statement pairs using pronoun objects (guest-list/
+  invitation context), demonstrative pronouns ("der/die/das" used as
+  standalone pronouns, not articles) in shop/conversation dialogues
+- Relates to *Menschen* Lektion(en): **L6** (Akkusativ — L1 extends this
+  to full personal-pronoun objects: mich/dich/ihn/sie/uns/euch/sie/Sie).
+  **New beyond Menschen A1.1**: **Dativ personal pronouns** (mir, dir,
+  ihm, ihr, uns, euch, ihnen, Ihnen — L1's second half) are not covered
+  in Menschen A1.1, which doesn't formally introduce the Dativ case.
+  **Demonstrative pronouns** (der/die/das used to mean "that one," as in
+  L2) are also **new** — a distinctly different function from the
+  definite article the student already knows.
+
+## Grammar covered
+
+### L1: Personal pronouns — Akkusativ (reinforces L6) + Dativ (new)
+
+**Akkusativ object pronouns** (reinforces Menschen L6's Akkusativ intro):
+mich, dich, ihn, sie, es, uns, euch, sie, Sie — used as the direct object
+of a verb like einladen (Ich lade dich ein = I invite you).
+
+**Dativ object pronouns** — **new grammar**, not in Menschen A1.1:
+
+| Person | Dativ pronoun |
+|---|---|
+| ich | mir |
+| du | dir |
+| er | ihm |
+| sie | ihr |
+| es | ihm |
+| wir | uns |
+| ihr | euch |
+| sie (Pl) | ihnen |
+| Sie | Ihnen |
+
+Used with verbs that take a Dativ object, like **gefallen** (to please):
+Das gefällt mir = "I like that" (literally "that pleases to-me").
+
+### L2: Demonstrativpronomen — **new grammar**
+The words der/die/das/den/dem etc. can stand alone as a pronoun meaning
+"that one/it" (referring back to something already mentioned), instead
+of functioning as the definite article before a noun:
+- "Welcher Pullover gefällt Ihnen am besten? — Ich möchte bitte **den**
+  da." (that one there)
+- "Ist die Postkarte für John? — **Dem** habe ich schon eine
+  geschrieben." (to him)
+
+This is grammatically distinct from the definite article the student
+already knows (der/die/das + noun) — here there's **no noun following**,
+and the pronoun itself carries case marking, functioning much like a
+personal pronoun with extra emphasis ("that one specifically," not just
+"it").
+
+## Exercise summary
+
+1. **L1 Gästeliste** — match 11 sentence pairs describing who's inviting
+   whom (Akkusativ pronoun practice, part 1), then complete 7 more
+   sentences with the correct Dativ pronoun (part 2).
+2. **L2 Meinen Sie die da?** — match 10 sentence pairs, each answer using
+   a demonstrative pronoun to refer back to something in the question.
+
+## Answer key highlights
+
+- L1 (part 1, matching): 1→f) 2→d) 3→a) 4→h) 5→b) 6→c) 7→k) 8→j) 9→e)
+  10→g) 11→i).
+- L1 (part 2, Dativ pronouns): 12. mir 13. ihm 14. euch 15. Ihnen
+  16. ihr 17. dir 18. uns.
+- L2: 1→f) 2→d) 3→a) 4→h) 5→j) 6→b) 7→i) 8→e) 9→c) 10→g).
+
+## Notes / gotchas
+
+- **Both grammar points in this section (Dativ pronouns, demonstrative
+  pronouns) go beyond Menschen A1.1**, which sticks to Nominativ and
+  Akkusativ (masculine only) throughout its 12 lessons. Present as
+  enrichment, not review — don't assume the student can already form
+  these without guidance.
+- **Demonstrative pronouns are easy to confuse with the definite article**
+  since they're spelled identically (der, die, das, den, dem ...) — the
+  distinguishing feature is that a demonstrative pronoun **replaces** a
+  noun entirely rather than preceding one, and it carries slightly more
+  emphasis than a plain personal pronoun (es/ihn/sie) would.
+- **gefallen + Dativ** (Das gefällt mir) is a genuinely common everyday
+  pattern worth teaching even before full Dativ mastery — it's a fixed
+  phrase pattern much like "möchte," so it can be taught as a chunk.
+- **This is another short section (2 sub-exercises, 2 pages)** — pairs
+  naturally with Section K for a single combined practice session if
+  desired.
