I'm looking for online enrichment opportunities for my EG/PG first grader with a passion for science and social studies. He has not enjoyed online e-learning tools focused on Math basics like dreambox, aleks, khan. He will do them without complaint as part of his school work and homework but does not seek them out. He used to love out brain pop but kind of outgrew it. He seeks out Documentaries (watches the old popular mechanic series goodness gracious) and non-fiction books...thus I'm looking for something more content driven for him to explore over the summer at his own pace. I wouldn't mind a more engaging math platform if one caught his eye as well.

I'm not an academic person (and definitely not a STEM mom) myself thus these sources are not easy for me to find or evaluate.

Someone suggested JHU CTY but it is pricey. This I'm wondering if anyone has reviews to offer?
