Main Concepts

See that dividing a whole number by a unit fraction is determining how many of that unit fraction is in the whole number.

Divide whole numbers by unit fractions without visuals.

Use factor families to show that if a x b = c then c / a = b.

Reason that since there are b portions of 1/b in 1 then there must be a x b in a.

Use factor families to show that a / 1/b = c so c x 1/b = a.

Use visual fraction models to divide whole numbers by unit fractions.
