This freebie contains 18 pairs of irregular plurals. You can use your imagination and do whatever you'd like with them! Play memory, create long and silly sentences.....The CCSS L.2.1b references using frequently occurring irregular plural nouns, so I hope you can adapt this resource to support this.
This "Go Fish" style game from Mrs. Beattie's Classroom includes 24 common irregular plural nouns and their singular form. Students can use these as a matching activity, card game, flash cards, or any other purpose in your classroom!
