I love to use these flashcards for both assessing and teaching the concept of negation to my students. To use: print, cut, and laminate these cards (24 flashcards included.) You can simply use these cards as flashcards or incorporate them into a game! Present the flashcards to your students. Have them point to the correct answer. If you laminate them, you can have your student circle their answer with a dry erase marker! I have also included a data sheet so you can easily keep track of student progress with this skill!
