Exercise 1
Step 1
1 of 8
In this exercise, you should put the correct form of the verb in the present progressive.

**estar (to be) + present participle = present progressive**

Here is some useful information to help you master the **present participle**:
– ***-ar*** verbs have the ending ***-ando*** (e.g. camin*ando*)
– ***-er*** and ***-ir*** verbs have the ending ***- iendo*** (e.g. com*iendo*)

Step 2

Here is a table for the verb ***estar*** to help you:

|Singular |Plural |
|–|–|
|Yo **estoy** |Nosotros **estamos** |
|Tú **estás** |Ustedes **están** |
|Él/Ella/Usted **está** | Ellos/Ellas **están**|

*Camila (she)* is third-person singular, so we used the third-person singular form of *estar,* which is *”está.”*

*Decir (to tell/to say)* ends with *-ir*, so we added *-iendo* ending. The stem changed from *e* to *i.*

Step 4

5. Yo **me estoy vistiendo**…
*(I am dressing to go on a vacation.)*

*Yo (I)* is first-person singular, so we used the first-person singular form of *estar,* which is *”estoy.”*
