Two Literacy Centers that reinforce singular to plural nouns (and three bonus printable) There are also black and white printer-friendly options. I have been known to use the black and white versions in interactive notebooks. The students enjoy having their own version of a literacy center. :) COMING SOON!! Singular to Plural Literacy Centers (adding -es) AND Singular to Plural Literacy Centers (change the -y to -i and ad -es).
