Participles that agree, compress whole clauses, and dodge the -ing trap — spoken aloud.
A Spanish past participle used as an adjective agrees in gender and number with its noun: las puertas cerradas, los acuerdos firmados, una carta redactada en tono formal. The irregulars to own at this level are abierto, hecho, dicho, muerto, roto, visto, puesto, vuelto, escrito, resuelto. From there, absolute constructions compress a whole clause into an opener — dicho esto (that said), acabada la reunión, salimos, una vez firmado el contrato, no habrá marcha atrás. And beware the -ing trap: the gerund only expresses manner or simultaneity (respondió sonriendo, habla caminando) — where English uses -ing as a noun, Spanish takes the infinitive: me gusta leer, fumar está prohibido.
Below: the irregular forms, the agreement rules, the clause-shrinking constructions — and a way to get them into your mouth in real conversation, no drills, no fill-in-the-blanks.

Carla
Your grammar teacher for this pack
You won't fill in a single blank here — in the Participle Pig lessons you talk, and Carla keeps forcing the forms out of you at speed. She feeds you five verbs — abrir, decir, hacer, ver, romper — and you produce both the compound tense (he abierto) and the adjectival use (una puerta abierta), agreement and all. She hands you a clunky clause and asks for the elegant version: cuando terminamos la reunión, salimos becomes terminada la reunión, salimos. Then she springs three English -ing phrases on you — I like running, the running water, while running — and you have to land correr, el agua que corre, mientras corro. Out loud, in conversation, until the right form arrives on its own.
Blank mid-sentence and nothing bad happens — she waits. That's the practice, without unnecessary judgement.
Quick answers
The core set: abierto (opened), hecho (done), dicho (said), muerto (dead), roto (broken), visto (seen), puesto (put), plus vuelto, escrito, resuelto. You'll meet them constantly as adjectives: la tienda está abierta hasta medianoche, el trabajo hecho a mano tiene más valor.
As adjectives, always — in gender and number with the noun: las conclusiones alcanzadas fueron unánimes, los documentos revisados contenían varios errores. In compound tenses with haber the participle stays invariable.
"That said" — an absolute participle construction that replaces a whole subordinate clause: dicho esto, paso al siguiente punto. Same family: visto el informe, la decisión parece clara and una vez hecho esto. They're the mark of polished, C1-level Spanish.
For manner or simultaneity: caminando por el parque, me encontré con un viejo amigo; respondió a la pregunta sonriendo; estudiando cada noche, logró aprobar el examen. Not for results, qualities, or nouns — that's English -ing interference.
Usually with the infinitive, not the gerund: me gusta leer antes de dormir (I like reading), fumar está prohibido (smoking is forbidden), se cansó de esperar (he got tired of waiting), gracias por venir (thanks for coming). After a preposition it's always the infinitive.
