This activity can be used with content vocabulary or sight words. A student chooses a heart and reads the word written on the heart out loud. Then she reads the labels on the buckets. Put the heart into the bucket that describes a category the word fits into. For a challenge, a partner must use the word in a sentence. Take turns picking hearts.
Instead of hearts, you can also make this center with other holiday shapes and just change the title of the center: shamrocks--Lucky Words, snowman--Winter Words, etc.
