  1. I think you have a typo on the largest value, shouldn’t it read 1x + 2 = 9?

  2. I think I would also use this with a fraction coefficient, so students have to fill in 4 boxes.

  3. I also like the idea you did at CMC where students would need to find the number closest to 0!

  4. How about 1x + 2 = 9876543
