Sylvia Vardell is an authority and Ambassador of POETRY FOR CHILDREN in USA. http://poetryforchildren.blogspot.com.au/

For any humorous poetry fans out there, you might want to check out THE FUNEVERSE in UK. Like ACP, it’s a free resource for schools and children. Here, poets, illustrators and kids come together to exercise their creative funny bones and write funny verse. http://www.thefuneverse.com

Also based in the UK is THE DIRIGIBLE BALLOON, where you’ll find another stash of free poems for children (with some familiar author names from ACP). https://dirigibleballoon.org/

World Poetry Day is 21st March:
