Lexia (available through Clever) - this is a great resource to work on word study skills, phonics, and reading comprehension. Your child progresses through levels that increase with difficulty as they grasp new concepts.

This would be great practice for struggling readers. Students can also leave reviews for each book. Parent information for accessing Benchmark is coming soon.
