The simple, repetitive sentences are accompanied by clear images that support the text to aid in memorization. The bright images and easy—to—read text make the book appealing to young learners and older emergent readers. Children will learn the essential Fry sight words and gain confidence as readers as they learn to read independently and with joy.
