What if you had to walk across a room, but every single step was exactly half the size of your foot?
You wouldn't count by whole numbers like 1,2,31, 2, 3 — you would count by fraction steps!
A unit fraction is any fraction with a top number (numerator) of 11, like 14\frac{1}{4}, 13\frac{1}{3}, or 12\frac{1}{2}.
To count along a number line by a unit fraction, we split every whole number space into equal parts matching the bottom number (denominator).
What happens when you keep hopping past 11?

Hopping Forward Past One

When you take four hops of 14\frac{1}{4}, you land on 44\frac{4}{4}, which equals one whole.
One more hop lands on 54\frac{5}{4}, which we can write as the mixed number 1141\frac{1}{4} because it is 11 whole plus 14\frac{1}{4} more.
A common mistake is resetting back to 14\frac{1}{4} after 11 and forgetting the whole number in front — remember to keep that 11 as you keep moving right!
Can we walk backward along the line just as easily?

Counting Backward by Fractions

To count backward, we subtract one unit fraction with each hop to the left.
