There isn’t really much I can teach a second, third, or fourth grader about etymology because the word alone would probably melt their brains. Instead it would have to be something very subtle. For example just like we did in class the packet of the Word Origins and how we went over the clues to be able to determine whether it was Anglo-Saxon, Latin, or Greek. Maybe take a designated time to go over the clues and have them posted up on a wall somewhere in the classroom where it would be easily noticeable. Then when we do our vocabulary and spelling words for the week also kind of test their knowledge to see if they know if the root of the word is Anglo-Saxon, Latin, or Greek with the assistance of the clues posted on the wall. Hopefully as time goes on they will start to pick up on the clues and be able to notice the roots of the words almost effortlessly.
Another example could be going over the clues for a certain period of time till the students have a pretty good understanding of how how each language differs. Then I would set up a type of benchmark assessment (not for a grade) and have a bank of multiple words. From there the students will need to correctly split the words into their correct category, either Anglo-Saxon, Latin, or Greek. The reason I say not for a grade is because for the age level that I aim to teach I don’t feel it absolutely necessary for my students to have a full grasp on this concept as it is somewhat difficult.
