I created this activity for my students to practice sorting their suffixes -ed to show the past tense and -ing to show present and future tense. Students read the base word and underline it, then circle the -ed or -ing suffix. Then, they cut, sort and glue the words in the correct category. This can be used as part of a minilesson, seatwork during centers, homework, morning work or as an assessment! Check out all of my other suffixes and plurals worksheets and activities!
