We made this Wormy W using:
Chipboard cut from a cereal box for letter base
Brown scrapbook paper
Glue: stick and hot glue to adhere worms
A Worm book we like:
Yucky Worms by Vivian French and Jessica Ahlberg (illustrator) is a fun book about discovering scientific facts about worms as the reader is taken on a gardening journey with a little boy and his grandmother. Although the little boy is grossed out by worms in the beginning of the book, he soon learns to appreciate the slimy creatures as he becomes more knowledgeable about the role of a worm and just how dependent we are on those little creepy-crawlies.
