I would recommend a couple: Khan Academy is great for specific topics (such as a focus on multiplication since you can type in what type of videos they need). I would also suggest Freckle. This has both reading and math and parents can sign up for free. We have this through our district so the parent may want to check if it is used at the school!

One of the best places for great resources can be anything online that the district's adopted program offers. i.e. we utilize Eureka squared - and there is a home- school connect feature etc. Our resource room teachers rave about Zearn: Zearn Math | Top-rated Math Learning Platform @ https://www.zearn.org/

Prodigy! It’s gamified learning and an adult can assigned specific skills and receive reports. Additionally if the students needs fact fluency practice, Reflex is my go to. It does have a cost but highly worth it.

Our district uses Dreambox as our online platform. It is adaptive to the student’s understanding: I also like Zearn and Reflex.
