In Spanish, adjectives need to match the nouns they describe.

This means that both need to have the same gender (male or female) and number (singular or plural).

Gender Agreement:

• Masculine:
  For words that are male, use adjectives that end in -o.
  Example: "El perro grande" (The big dog).

• Feminine:
  For words that are female, use adjectives that end in -a.
  Example: "La casa grande" (The big house).

Number Agreement:

• Singular:
  If the noun is one (singular), use the regular form of the adjective.
  Example: "El niño alto" (The tall boy).

• Plural:
  If there are two or more (plural), add -s or -es to the adjective.
  Example: "Los niños altos" (The tall boys).
  Example: "Las casas grandes" (The big houses).

Practice:

1. Write sentences using different nouns with the right adjectives.
2. Check the gender and number of the nouns. Make sure to change the adjectives to match.
