Use two rulers, or make two movable number lines.
Using the ruler, mark at the start, and at the point 1 2/3. Now at that point, measure again 1.56. The sum will be the distance from the final point to the original start point.
make an illustration depicting the number line to find each sum or difference
1 2/3 + 1 5/6

This site has several illustrations of number lines with fractions.
