This pack includes three sheets with 10 photo pairs on each sheet. There are a total of 30 pairs or 60 words with photos. They are perfect for children with language disorders that need to target irregular plurals. They can be used on the table in front of students. They can visually see how the words change. They can use words in sentences. As they complete each pair, they can mark them off with game tokens or magnetic dots. When the mat is done, they can play a game or use a magnet to pick up the dots. The Irregular Plural Noun mats are also great for home practice. They can also be cut into flashcards and used to play games like "memory match" and "fish" by matching the noun to the irregular plural form.
