Make a big book to add to your dinosaur theme resources. Instructions are included to make a big book that reveals the stegosaurus as you read or sing the story. A letter of the word stego disappears with each verse, and a bone appears in its place. Children clap where the bone takes place of a letter. Contents include: Overview, How to make a big book, How to read Stego, Patterns, Puzzle patterns, Rebus chants, and Letter to the class. Sing the song of Stego to the tune of "Bingo". Stego appears on the left hand side of the book as the pages turn. The text starts out large and becomes smaller as the pages are turned. Students will participate singing a song and will clap in rhythm to the song. This Animal Science lesson provides a teacher and student section with big book, puzzles, and rebus chants to create a well-rounded lesson plan.
