Alright, here's MY taste;
5. Super Why
Now, not my all time favorite, but I have to admit; entertaining enough to keep me hooked in when I was in Kindergarten up to 3rd Grade.
4. Wordgirl
Kinda simple; she's a complete menace, and watching her obliterate villains was quite a laugh for me.
3. Daniel Tiger's Neighborhood
This one has Sentimental value for me, almost. It taught me a lot of lessons that were blossomed into my current life, all the way until 4th Grade. Man am I ever grateful.
2. Clifford the Big Red Dog
Easy to guess why; he's just a little- erm, big puppy who likes spreading love! Since I love dogs to near death though(protect and care, not the other one >:<), its what primarily boosted this one to 2.
1. Odd Squad.
Do I have to explain this one? We all love this one, c'mon!
Honorable Mention for me: Dinosaur Train
This helped teach me a LOT about Dinosaurs growing up. And I'm sure it helped teach you some if you watched the show. Man do I miss the good old days.
