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.
This is a great resource for a 2nd grade classroom. It's a great time filler or extra practice. You could put it in centers. The passages aren't too long, but it is cheaper in a teacher resource store (9.99)
I bought this set of cards for my son. Love it! It provides an easy way to help my son on practicing his reading skill. Very handy. We carry it around and practice even while waiting for restaurant seating.
