These words should be words to know by heart. We call these words our "heart words". The word cards have no more than three words on them. Students keep them on a ring for easy transport to and from home. Each day they can read the word, they color a heart under that word.
They also track their own progress of sight words on their sheet. After they know 25, 50, 75, 100 sight words they receive a certificate.
It is another easy way for me to see what words they know by heart and which ones need more practice.
