Technology offers parents many engaging resources to keep kids learning.
Interested in providing a bit of extra education disguised as fun to the kiddos this summer? Today's technology offers parents many engaging resources to keep kids learning beyond the brick and mortar classroom.

A good educational subscription should include several key features:

· Easy navigability

· Appealing to target audience

· Available across several devices

· Provides a means to track learning/progress

Sometimes, you really do get what you pay for. An amazing free educational app can be like a unicorn: everyone wants to find one, but no one ever has. Many "free" apps are often truncated versions of pay apps - enough to whet the appetite so a parent will pay for better, more diverse content. Many parents may already be familiar with Starfall and ABCMouse; here are some other educational subscription sites that parents have recommended.

1. BrainPOP

BrainPOP offers strong, engaging animation that makes learning fun. A distinguishing feature of this service is its diversity in both subject matter and service options. BrainPOP Jr ($99/year) offers opportunities for K-3, while Pop ($115/year) is for ages 4+. However if you're interested in introducing your kiddo to foreign languages, they additionally offer Spanish and French ($99/year). BrainPOP also developed an ESL-focused service as well.
