Plsease i suck at spanish HAHA

Okay so i'm taking an online spanish course (penn foster), and in the study guide, you have to create a bunch of sentences with words you've learned so far. translating, reading, and those kinds of things are fairly easy, but when it comes to making my own sentences, my brain just kinda waltz's away. anyone got any tips?

Select the word from the list that best fits the definition tu madre espera que tú en casa a las ocho. hable hagan sepa estès escribamos

Choose the correct family member in spanish. match term definition mi abuelo a) la hija de mi madre mi hermana b) el hijo de mi tía mi nieto c) el padre de mi madre mi tío d) el hijo de mi hija mi primo e) el hermano de mi padre
