Learning to read by sight is the key to early literacy. That's why high-frequency words worksheets are popular for preschool, kindergarten, and primary grade classrooms. Words like “the,” “and,” “it,” “to," and "do" often appear throughout stories. Having high-frequency words worksheets at home helps your little one with memorization so that independent reading is easier in later grades. With match games and word searches, worksheets make reading fun!
