Teacher's field guide

What Students Need to Do: Students spot a part added to the beginning or end of a familiar word. They explain how it changes the meaning, such as pack to repack or jump to jumped.
What Mastery Looks Like: A student can build untie, repack, and jumped from word cards. They can explain that the words mean undo the tying, pack again, and jump in the past.
Common Misconceptions: Students may think repack means unpack instead of pack again. They may think jumped means someone is jumping now.
How to Assess It: On a slip, print untie, repack, and jumped. Ask students to circle the added part and finish: “Untie means ___; repack means ___; jumped means ___.”

Lesson moves

Give students cards labeled un-, re-, and -ed, plus tie, pack, and jump; have them build each new word and act it out.
Ask partners, “What changes when pack becomes repack?” Have them explain using a lunchbox packed twice.
Play a matching game with tie and untie, pack and repack, jump and jumped; match each pair to undo, again, or already happened.
Post “Recheck your name” by the turn-in bin; ask students what re- tells them to do before handing in a paper.
