I visited Sergio's wallwisher:

The activity that I found there, it was easy, but, in my point of view, take a little review about irregular and regular verbs always is a good idea.

The second one, was Daniela Medina's:

This activity was easy too but always is important to learn new kind of clothes, so it was so helpful too.

The Third one, was Nathaly's wallwisher.

The activity was a little bit looked like the sergio's excersise, so I will say the same as I said about Sergio, it was very handful take a little review about verbs in a past time.

The last one, was Daniel's wallwisher:

To make a little sum up, it was the most interesting topic, because, the most of people, to ask for some information, they just use de WH questions, so practise de indirect questions was a great idea.
