This is a 10 question quiz on adding, subtracting, multiplying and dividing decimals. The questions are based on wildlife such as king snakes, rattlesnakes, lizards, eagles, ducks, and owls. It is aligned to the common core standard MCC6.NS.3. However, it can be used with any grade level that needs a practice worksheet, short quiz, homework, or a short study guide for a quiz on all operations of decimals. I hope you enjoy reading the questions and the surprise birthday given to the park ranger on the last question.
