This is a Subtraction Worksheet. The students are shown the words to the classic song "Row, Row, Row Your Boat" and asked to count the total number of words. Next, they are told to cross out every word "Row" and record that number. Finally, they are asked to subtract to find the remaining amount of words. This is a fun and clever spin on a simple subtraction problem. This is useful as homework, classwork, or in a math center.
