The document appears to be an activity sheet from a Brazilian elementary school. It contains the date, school name, spaces for a student and teacher's name, grade and class information. The activity asks the student to circle individual words in a song called "A Canoa Virou", count the total number of words, and remove all instances of adjacent vowels from the text of the song. The song is about a canoe that tipped over because Maria didn't know how to row.
