I have been teaching the Phonics for Reading program by Anita Archer for several years and I have found it beneficial to present the material in a variety of ways to keep students engaged and increase the amount of practice. This PDF file contains all of the challenge words in the second level of Phonics for Reading. When printed two sided (short side), each word will have the lessons it coincides with printed on the back. The flashcards can then be shuffled, sorted and presented as a timed challenge. I have offered the cards that go along with lessons 1-4 as a preview. Please visit my store for more Phonics for Reading resources! Thank you!
