  1. thank you for the task. Please edit the name.

  2. The directions say only digits 1 to 9. Please correct if you are using the digit zero (0). My solution was 5.6 + 1.4 + 2.98 using your allowed digits.

  3. 5.7+1.8+2.49

    My 6th graders said you could not use 0 in the directions 🙂

  4. Here is the beauty of Open – middle: discussions about what you didn’t think about.

    I think in the original problem you could replace the box for the numbers place with a zero.

    OR you could allow zero to be used, then?
    5.9 + 2.3 + 1.80 !
    Technically my answer is incorrect because the original problem says “”…as close to…” not to actually reach 10, so: 6.9 + 2.3 + 0.81 ! (You didn’t say we couldn’t go over 10)

    I’m sure there is more!
