Spanish "ser" conjugation worksheet for learning the present tense of "to be."

To solve this, we need to match the subject of each sentence with the correct form of the verb ser (to be) from the chart provided.

Here is the step-by-step breakdown:

1. Mi madre (My mother): This is singular and feminine, so it corresponds to Ella (She). The form is es.
2. Mis padres (My parents): This is plural, so it corresponds to Ellos (They). The form is son.
3. Mi primo (My cousin - male): This is singular and masculine, so it corresponds to Él (He). The form is es.
4. Yo (I): The chart shows the form for "Yo" is soy.
5. Mi hermana y yo (My sister and I): When you include yourself in a group ("we"), it corresponds to Nosotros. The form is somos.
6. Mi profesora (My teacher - female): This is singular and feminine, corresponding to Ella (She). The form is es.
7. ¿De dónde \_\_\_\_\_ Sarah?: The subject is Sarah (she/Ella). The form is es.
8. Sarah: Again, the subject is Sarah (she/Ella). The form is es.
9. ¿De dónde \_\_\_\_\_ tú y tus padres?: The subject includes "tú" (you) and others. In Spanish grammar, when addressing someone directly along with others, it uses the Vosotros form (You all). The form is sois.
10. Mis padres y yo (My parents and I): Just like number 5, this means "We" (Nosotros). The form is somos.
