Sight Words First Grade. The PoPular Words Activity is a fun, interactive way for students to learn/practice Sight Words. This Activity includes the top 100 common words for First Grade. Included is 4 sheets of “popcorn pieces/100 words” for First Grade level and a bonus sheet of blank popcorn pieces for additional words if desired. There is also a sorting mat for students to place the words they know and the words they need to work on further. (I recommend laminating the popcorn sheets, then cutting out the popcorn pieces.) The popcorn words can be stored in a paper or plastic popcorn container. Enjoy!
