Answer: It appears that you are learning the preterite tense, this is a little different than the present so don't worry!
Bascially instead of a verb such as hablo (I speak) we shall change the suffix in order to put the verb hablar in the preterite tense.
Step-by-step explanation:
So i'm not going to do your homework for you but i'll walk you through how to put verbs in the preterite.
For -AR verbs we must take off the -AR and do as follows, for an example i'll use the verb hablar again
Yo- Hable (with accent over e, my computer wont allow)
Tu- Hablaste
El,ella,ud.- Hablo (accent over o)
Nosotros- Hablamos
Ellas,Ellos,Uds.- Hablaron
For -ER and -IR verbs (remember they copy each other) it shall be the same thing. This time i'll just do an -ER verb.. i'l use comer.
Yo- Comi (accent over i)
Tu- Comiste
El, Ella, Ud.- Comio (accent over o)
Nosotros- Comimos
Ellos, Ellas, Uds.- Comieron
In number two you have an irregular verb, this being dar (to give)
As you can see Dar is an -AR verb although dar copies the -IR endings so you will see dar as
Yo- Di (accent over i)
Tu- Diste
El, ella, ud.- Dio (accent over i)
Nosotros- Dimos
Ellas, Ellos, Uds.- Dieron
