Spent a few minutes with Google looking for a decent app or website we can direct our kids to for working on the skills and concepts being introduced in the classroom. We are open to a subscription service, but don’t want to commit without some endorsement or referral from a trusted PDDer. Sure, there is plenty out there for free, but weeding through advertisements and such makes it complicated and cumbersome at times – we’d also like to track progress. Any of you using anything you can recommend? Specifically looking for math, spelling and phonics for the K-5 audience.
