<em>Las pizarras son larg</em><em>a</em><em>s</em>
<em>Pizarra </em>is a fem. singular noun. Generally speaking, fem. singular nouns interact with their corresponding adjectives matching each other when it comes to their quantity and if they are masculine or femenine. So: <em>pizarra larga</em> (singular), <em>pizarras largas</em> (plural); <em>coche azul</em> (singular, masculine), <em>coches azules</em> (plural). Note you add an -es termination when the word does not end with a vowel (<em>azul, azules; lápiz, lápices</em>, and so on. Such rule applies to both nouns and adjectives).
Además, nos interesa mucho visitar todas las cataratas que encontraste en el Parque Nacional Canaima. ¿Hay algún lugar donde yo pueda sacar fotos de las cataratas desde cerca?
The first verb is conjugated in the imperfect indicative ("<u>encontrar</u>") while the other verb is conjugated in the present subjunctive ("<u>poder</u>").
