Two ways to complete the mazes. Students can just draw a line, or they can circle fact families. (Keys for each way are included) If students are moving left to right with a problem, they will refer to the plus or minus symbol for that row. If they are moving top to bottom, they will refer to the plus of minus symbol for that column. This is a more challenging activity. There will always be 8 problems before the finish (4 addition and 4 subtraction).
