Printable 8x11 decorative posters for the Four Rules for Adding Suffixes. Poster designs are from the PowerPoint Lesson "The Four Rules for Adding Suffixes." The rules include: 1- Just add it to the end of the word, 2- For words ending in a silent e, drop the final e if your suffix begins with an a, e, i, o, u or y, 3- For words ending in one vowel and one consonant, double the consonant before adding a suffix that begins with an a, e, i, o, u, or y, 4- For words ending in a consonant -y, change the y to an i before adding any suffix except -ing. Rules come with different chevron print backgrounds. File includes Suffix Posters, Four Rules for Adding Suffix Posters, and Four Rules for Adding Suffix Posters with cute monster Graphics. I have included Common Core Standards and TEKS that correspond with the content of the posters.
