What children learn in Level 11

Welcome to the Word Parts Workshop! Many long words are built from parts. A prefix is a part added to the beginning of a word, and it changes the word's meaning.
Re means again: reread means read again. Pre means before: preheat means heat before. Mis means wrongly: misspell means spell wrongly.
Un, dis, and non mean not, or the opposite of. Unhappy means not happy. Unlock means do the opposite of lock. Dishonest means not honest.
To figure out a new word, cover the prefix, read the root word, then add the prefix's meaning back.
Your turn! Sort these words by what their prefix means.
