To calculate the overall star rating and percentage breakdown by star, we do not use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
I have purchased several of these Edupress card sets and my students really enjoy them. I am an elementary Special Education teacher and I use as part of my Specially Designed Instruction (SDI). These are great for those students with below grade reading levels. It helps support state standards but are micro passages which are less overwhelming for the students I support. I tell my students this type of practice will help them build confidence on longer passages in district and state assessments. Fyi, I created a half-page log so they can record their answers by card set and card number. It's easy documentation (in their handwriting, name, date, and card set focus...e.g., comprehension/drawing conclusions) and we even record percentage right/wrong. This has proven, at least for my students, to be a great motivator. The only reason I didn't give it five stars is because the decks average 40 cards and they are one sided. Two sided would be better by doubling the set without adding more cards.
I teach ELA to 4th graders and one of the KEY strategies is to get them looking for "clues" in the text that give hints as to the meaning of unknown words. This set of cards can be used independently, or in pairs or at a station to practice this skill. The vocabulary words are probably more suited to 3rd graders, but still are helpful to 4th graders (too easy for 5th grade, in my opinion).
