I highly recommend using the Newmark Learning books! :) They have series from grades 3-8 in reading, math and Language. I do not know about the math or language series but I do love how the reading is set up!! It has a variety of different texts, paired passages, Part A/B questions, open ended questions, short & extended response! :)
If your looking for a book that will help your kids on PARRC... This is definitely it! They run for about 15-20 on amazon!! ;)
