期間に〜回／冊／本kikan ni ~kai/satsu/hon

How it works
Look at the two one-week boxes: each has one book, showing that you read one book every week.
「１週間に」 uses one week as the unit and gives the quantity within that period.
Use 「回」 to count how many times you do something, 「冊」 for books, and 「本」 for movies.
In 「１週間に１冊本を読みます」, state the period and quantity first, then say that you read books.
To describe your reading habits more specifically, use 「１週間に２冊」 to say how much you read.
In the example, 「１冊」 is read 「いっさつ」. Notice the brief pause for the small 「っ」.
「４、５本」 means about four or five movies, not four plus five, making nine.
In the example, 「本」 counts movies and is read 「ほん」: ４本 is よんほん and ５本 is ごほん.
