This activity came from the book "Because of Mr. Terrupt". We read this book as a read-aloud this year and my kids were so in to the idea of finding "dollar words". So, I made up and created the exact activity the students in the book did. The kids have to record words down on their page and then add up the value of each letter to come up with an overall total value for the word. Their goal is to find words that equal one dollar exactly. It's a fun challenge and a great way to practice working with place value and decimals.
