Learning target I can divide a whole number by a fraction, a fraction by a fraction, and a mixed number by a fraction, by turning whole numbers and mixed numbers into fractions first and then using Keep, Change, Flip.

Start hereWords for this lesson

Read each word before you begin. Say it out loud.

WordWhat it meansExample
ReciprocalSpanish: Recíproco A fraction turned upside down.
DividendSpanish: Dividendo The number being divided — it comes first in a division expression.
DivisorSpanish: Divisor The number you divide by — the one you flip in Keep, Change, Flip.
QuotientSpanish: Cociente The answer when you divide.
Mixed numberSpanish: Número mixto A whole number and a fraction together, like 2 1/4.

Say it and write itSentence starters

Finish each sentence out loud with a partner. Then use them in your writing.

Watch outA common mistake

A common mistake is starting Keep, Change, Flip before every number is a fraction. Always turn whole numbers and mixed numbers into fractions FIRST — otherwise the flip happens to the wrong thing.
