Common misconception
When counting, children might think that 1 comes one step after the numerator and denominator are the same. For example, "...five-sevenths, six-sevenths, seven-sevenths, 1".
As the teacher, count in a given unit fraction and ask the children to stand up, wave or respond in some way when you get to the unit fraction that's equivalent to 1 (when the numerator and denominator are the same).
