# Adding Fractions - Math Lesson Plan Template

The interactive white board tool for this lesson can be found on our
website under Resources and Teacher Tools.
( )
In this DreamBox lesson, students use fraction tile manipulatives to find
the sum of the fractions. Using the tiles, students demonstrate the
answer visually and then numerically. The interactive whiteboard tool for

Sample Lesson
Objective
Using both a concrete bar model and equations, this tool enables students to
best to solve a given problem.
Background
Students should have background knowledge of equivalent fractions.
Instructions
1. Open the lesson on an interactive whiteboard or data projector and have
students create the solution by drawing the fraction tiles on paper or individual
white boards.
2. Invite students to form groups based upon common solutions, showing them a
variety of solutions and strategies are possible. Then have one person from each
group explain why their answer works as a solution.
Possible strategies:
a) Students use the unit fraction and count out each given fraction within the
equation.
b) Students use equivalent fraction combinations to create each individual
fraction within the equation.
c) Students use equivalent fraction combinations to create the sum of the
fractions.
d) Students may come up with alternative strategies as well.
3. Ask one student to solve the problem and determine the accuracy of their
