Six pages on the word endings first graders read and write: -s and -es, -ed and -ing, on base words that keep their spelling (jump, jumps, jumped, jumping). Children write each base word with its endings, circle the base word inside a longer word, sort -ed words by the sound it makes (jumped says t, filled says d, melted says id), sort words that take -s or -es, and read sentences to choose the ending that fits.
Write a base word on the board and add each ending in another color. Act the forms out: "I jump. Yesterday I jumped. Look, I am jumping!" For -ed, have children put a hand on their throat to hear the d and feel the t.
Pick an action word and use it three ways: "You walk. You walked. You are walking." Let your child find the base word in each.
Worksheets on the endings -s, -es, -ed and -ing added to base words such as jump, fish and help, whose spelling does not change. Children add each ending, find the base word, sort -ed words by the sound it makes, choose -s or -es, and pick the word that fits a sentence.
