Peggy Penguin’s Plural Rules is a set of posters which include the rules for changing singular words into their plural forms. I am currently using these posters to help my 3rd and 4th graders read and write plural words.
The posters are in PDF form. Posters are the size of half a letter size sheet of paper. There is one set with a penguin in each poster and one set without any clipart. The set includes:
8 posters of rules (y, f, fe, o, ch, sh, x, z, s)
1 poster for irregular plural words
1 poster for words that are both singular and plural
Total of 11 posters (with and without a penguin)
