Grade 3 Units 2 and 3 Present Perfect Interview Sheet

Here's an interview sheet that the students can use to interview each other with questions like this:
How long have you known your English teacher

After talking to their friends and then writing down the answers in the appropriate places they then have to tell the class what they found out about their friends. The answer to the above question might be:
I have known my English teacher for two year

But when the interviewer reports he or she has to change the grammar to:
Hiroyuki has known his English teacher for two years.

It might be a good idea to break this up into two activities covering two classes. Collecting the information in the first and reporting the information in the second. Before the reports the teachers can review the grammar.
