Subtracting Fractions

Introduction

Calculator demo + recap of previous lesson ~ 5 minutes

Students are given a demonstration of how to add mixed number fractions using a calculator

Body

Get to 10 or Get to 100 ~ 15 minutes

This game will vary depending on how advanced your students are.

Break them into partnerships to play. Give each pair two dice labeled with mixed numbers; more advanced mathematicians can play with three, four, or even five dice. The first player rolls the dice and use a calculator to get the sum. Then, the second player takes a turn.

The goal is to get to 10 or 100 first, depending on the mathematical level of your students. The first player to get close to 10 or 100 without going over is the winner of the round.

Modification:

• Use of a calculator instead of mental calculation.
• Students write the equations into their books as they play the game.
