Math Trail from HeyMath! is a series of map-based math trivia challenges. Each game follows a trail of locations that students have to find by using the clues provided. When they arrive at the correction location students have to answer the multiple choice math question presented to them before moving on to the next question in the trail. Math Trail provides a nice blend of geography questions and math questions appropriate for 5th to 8th(+) grade students.
FYI: There doesn't appear to be a guide for level of difficulty for math questions used with each trail & they are not labeled with Common Core standards. These trails are great for students to explore on their own, but you could have students go through a trail together using the interactive whiteboard.
