Integer Trails Subtraction
integers · subtracting integers in trails
To subtract integers [7.NS.A.3].
Integer Trails Subtraction is a Grade 7 grid puzzle where students create a trail whose integer subtraction leads to the value in the ending square. Paths move only horizontally or vertically, cannot cross, and may use each square once. Those restrictions force students to think about both the arithmetic and the route they choose through the board.
Use it for partner or small-group practice after students understand subtraction with positive and negative integers. The puzzle format makes it natural to test, revise, and explain a trail rather than simply mark an answer right or wrong.
