Add a little, change a lot
First graders meet their very first word parts. They learn that adding a few letters to the front of a word can flip its meaning: un + lock = unlock, re + do = do again. They practice the friendliest prefixes like un- and re-, alongside endings like -s, -ed and -ing. The aha moment is when a child reads "untie" and says, "Oh! That means the opposite of tie!"
With 1st graders, keep it to one or two prefixes and lots of hands-on matching.
Kids match a prefix animal to a base word animal and read the new word aloud. Start with just un- so it feels easy, then add re- the next day. Matching makes a new idea feel like a game.
Why it works: in a well-known study, a few short sessions of a simple number board game measurably boosted young children's number skills (Ramani and Siegler, 2008).

Why it works: pulling an answer out of memory makes it stick far better than rereading it, one of the strongest findings in learning research (Dunlosky and colleagues, 2013).

Yes, in a simple way. First graders learn a few common prefixes like un- and re- and how they change a word's meaning, along with endings like -ed and -ing.
Un- means "not" or "the opposite of." Unhappy means not happy, and unlock means the opposite of lock.
Tell them a prefix is a little word part at the front that changes what the word means. Show them with real actions, like tie and untie or pack and unpack.
Use everyday actions: pack and unpack groceries, zip and unzip a coat, fill and refill a cup. Say both words and ask what changed.
