Gender, number, types and irregular plurals in Spanish
Master Spanish nouns: identifying nouns among other word classes, feminine gender exceptions in -o words (la mano, la foto), plural of -z words (pez→peces), collective nouns (bosque), abstract nouns (amor), epicene nouns (la serpiente), and invariable plurals (la hipótesis/las hipótesis). 15 questions from Primary to Secondary.
The noun is the most basic grammatical category and, at the same time, one that hides the most exceptions in Spanish: masculine words ending in -a, feminine words ending in -o, plurals that completely change the root. Mastering it well is the foundation for everything else in grammar.
The exam covers the most frequent gender exceptions (la mano, la foto, la moto), irregular plurals (pez→peces, régimen→regímenes) and noun types —proper, common, collective, abstract, epicene— with real curriculum examples.

Words ending in -o are usually masculine, but key exceptions are feminine: la mano, la foto, la moto, la radio. The exam works through these with explanations.
Pez→peces, régimen→regímenes, hipótesis→hipótesis (invariable). Systematic rules for each case: -z changes to -ces, stressed -s words don't change.
Proper vs common, concrete vs abstract, collective vs individual, epicene (one form for both sexes). Questions use real curriculum examples.
"A Year 5 student thought "amor" (love) was a concrete noun. After seeing that it cannot be touched or seen, they understood the abstract noun category — and could apply it to the whole group."
