This document provides an overview of a lesson on dividing fractions and mixed numbers. It includes:
1) Learning objectives for students to divide fractions by mixed numbers by first converting mixed numbers to improper fractions, and to use equations to find quotients.
2) An example problem walking through dividing a mixed number by a fraction.
3) A matching game activity for students to practice dividing fractions and mixed numbers.
4) A closing reflection question comparing dividing fractions by mixed numbers to previous work dividing fractions.

Matching Game
The goal is to match each expression with the equivalent quotient.
Each expression is assigned a letter. Students must show their work in
that box on the student materials. Once they have solved a particular
problem, they will not have to solve it again if they record their work in
the correct place.
Students are able to flip two cards over during each turn. If the
expression and the quotient do not match, both cards should be flipped
back over. If the expression and quotient do match, the student keeps
the matches to determine a winner at the end.
Suggestion: Solve the problems on the next screen first, then play the
matching game.
