Goodbye Mathew!

Today was Mathew's last day at our school.  We are very sad that Mathew is leaving because he was a good friend to everyone in Space 5.  He has been working very hard this year and we will miss his cheeky smile!  We hope Mathew will have lots of fun at his new school.  Good bye Mathew!

What am I?

Read the clues that Mathew wrote and see if you can guess what animal he is!

I am big.  I have two horns.  I eat grass.  I am a boy.  I charge at people.  I live on a farm.  I'm angry and fast at running.  What am I?
