Math 7 – Solving Proportions
COS Standards
AL.ALEX.2010.MA.7 - 3.) Use proportional relationships to solve multistep ratio and percent
problems. [7-RP3]
Concurrent Skills/Competency Focus
Listening, following directions, solving simple multi-step equations
Instructional Objectives
TSW use proportions to solve problems.
INSTRUCTIONAL PROCEDURES
SET: TTW ask students if they have ever heard of a proportion and will explain that they are
similar to equivalent fractions. TTW explain the vocabulary at the beginning of the PowerPoint:
equivalent ratios, proportion, cross products.
TTW use the attached PowerPoint to explain what a proportion is to students.
TTW use the example problems in the PowerPoint to instruct students on the steps to solving a
proportional equation: write the proportion, find the cross products and multiply, divide and
solve for the variable.
TTW work more example problems, calling on students to answer questions as the teacher works
through the steps.
CLOSURE: TTW use the popsicle stick method to randomly draw students names to answer
questions about the steps to solving proportions and the steps to another example problem.
MATERIALS/RESOURES
Solve Proportions PowerPoint
Projector screen
Cup of Popsicle sticks with students’ names on them
ASSESSMENT
TTW use the Popsicle stick method to randomly draw students’ names to answer questions about
the steps to solving proportions and the steps to another example problem.
ASSIGNMENT
TSW be assigned homework problems in the textbook.
ADAPTATIONS/ACCOMMODATIONS/MODIFICATIONS
Academic: Provide student with copy of the PowerPoint; explain that after cross multiplying the
proportion, you solve it just like a simple multi-step equation; make sure the student is on the
correct page in the textbook for the homework assignment and give a personal cue to get started.
Behavioral: Seat the student close to the teacher; check to make sure the student is on task and
copying the notes; let the student aid help student with homework assignment
