Teach your students about argumentative writing by using the Poison Pen Murder Mystery as a basis.
Start by passing out The Daily Telegraph as an overview of the criminal case.
Then allow your students to work in stations to record details about the 8 suspects on the suspect chart.
Afterwards, implement the argumentative essay process to have students develop claims about the perpetrator and convict a suspect.
Twist: There isn't one definite perpetrator! This is a lesson to encourage students to investigate clues and then develop an argument with evidence.
