Formative Assessments: Positive and Negative Adjective Flyswatter

By Elvira Siahaan, Indonesia

15 minutes

Lesson Plan

Learning Objectives: 

  • Flyswatter is a formative assessment tool, meaning it is an assessment conducted during the lesson in order to modify the lesson as needed. 

  • This version of flyswatter assesses students’ comprehension of positive and negative adjectives.


  1. Assuming you have already taught positive and negative adjectives prior to this assessment, lead a quick review of the vocabulary. “What positive and negative adjectives did we study? Let’s write them on the board.” As students share the vocabulary, write them down, scattered across the white board. 

  2. Lead a quick review of opposites by pointing to adjectives on the board. “What is the opposite of early? Can you find it on the board?” 

  3. Divide the class into two teams and give each team a flyswatter or sticker. Teams should form separate lines.

  4. Explain that the teacher will say one adjective. Representatives from each team must turn to the whiteboard and find the opposite adjective. For example, if the teacher says, “Stingy!” the students must find the word generous. The student who hits or puts a sticker on the correct word first is the winner. 

  5. Representatives should keep rotating each word to give every student a chance to participate. 


  • If you do not have flyswatters or sticks, students can just slap the words on the board directly.

  • Students can become too excited or competitive, so set clear expectations regarding acceptable behavior. 

  • Teachers can keep track of points to choose winning teams, but often this is not necessary because it creates unneeded competition. Students tend to enjoy it regardless of points. 

  • Remember that this is not only for fun. This is a formative assessment, so based on the results, review the material again or move onto the next activity.
