Turtle Diary offers a strategic selection of mixed operation games specially designed for second grade math level. Mixed operations, also known as order of operations, are simply the collection of rules that dictate the order in which to evaluate a math problem. Although mixed operations can become complex in later grades when multiplication and division are layered on, it's important for second graders to be introduced to the basics of mixed operations to become familiar with how to approach math problem solving. The concepts covered in Turtle Diary's mixed operations games for kids include fact families and addition problems. Fact families are a collection of related addition and related subtraction problems that are made from the same numbers. Our interactive mixed operations games integrate advanced design elements that animate the games and make them come to life. We guarantee that your second grader will love engaging with our games so much that they might not even realize they are educational. Perfect for at home or in school, Turtle Diary's online games truly provide a unique educational experience for second grade students.
