This year my school kiddos had a lot of practice with +/-1 and +/-10 with NUMBER MAZES. They were challenging yet a hit among first and second graders. The mazes I made go up to 120 and range in difficulty. I placed these in plastic sleeves and the kiddos used dry erase markers to complete. They start at the first number and then follow the path and add the number that belongs in each space.
