Fractions on Number Lines

Equal intervals between whole numbers locate fractions and make their size comparable. The denominator sets equal interval size and the numerator counts intervals from zero. A careful solution names the quantities, keeps place value or units visible, and explains why each operation fits.

Worked reasoning
