The One Dollar Word Riddle Book is a great book to use when teaching money, adding decimals or enrichment! The book is full of pictures, riddles, and even a story with words that all equal $1.00 when you add the value of the letters in the word together. For example, a = .01 b= .02 c = .03 and so on. I created an activity of words I have found that relate to a beach theme. For the extension, students are asked to find the value of their own name, classmates, names, and a day of the week. A great cross-curricular activity using picture books in the Math classroom. My teacher friends have even used this book on the 100th day of school!
