Sort the pairs of words as synonyms or antonyms, then record on the accompanying sheet. Just copy on a pretty color of cardstock and laminate and you have a nice, new, engaging, Springtime center for practicing synonyms and antonyms. The sheet should be copied front to back. Also for sale--check out my practice pack of 3 sheets of synonyms and antonyms in which they color the pairs if they are synonyms or antonyms. What a great week-long language arts unit complete with hands-on activity and practice sheets.
