Algebra Lab is an online learning environment that focuses on the high school math topics and skills called upon in introductory science courses. It has an excellent glossary and math topics appropriate for our learners. These include fractions, decimals, exponents, order of operation, and word problems. It provides vocabulary development and practice of language in a context related to math and science. Includes extensive teacher support, lesson plans, practice exercises, comprehension exercise, and more. For this activity, you will be presenting Order of Operations.
Preparation

How-To
Preview the site.
Select a topic
Use the lessons available (see Order of Operations URL above).
Open the class discussion
Hand out the worksheet, Order of Operations (see Example Document 1 above) Assign work in pairs or teams, including example problems online
Review the assignment in class so you are available to answer questions.
Teacher Tips
This site includes a section for teachers explaining how to best use the site. You will find it under Directions. There is audio support in some of the sections.
More Ways
This site has an excellent glossary of math and science terminology.
The Passages section applies math to science situations, for example, 'Understanding solar eclipse'. The passages end with multiple choice questions and answers.
There are reading applications including main idea, author's purpose, vocabulary, cause and effect and analyzing information

Warm-up
Engagement
Review basic operations by giving student pairs example problems, one per operations. Ask if there were any difficulties in need of review.
Introduction
Write an equation with both addition and multiplication. With a partner, ask students to solve the problem.
If you add left to right, you get one answer. If you multiply left to right you get another answer. Ask students to discuss this dilemma.
Introduce Order of Operations
Presentation
Engagement
Present PEMDAS and list what each letter stands for on the board.
Be sure to give examples of each.
Practice
Engagement Enhancement
Use the worksheet found at the bottom of this activity. Students can work in pairs to decide on the answer to each problem.
Evaluation
Engagement Enhancement
Create a formative quiz to evaluate students' knowledge of the order of operations.
Application
Engagement Extension
Order of Operations is extremely important in solving mathematical problems. Have students discuss how they will use what they learned in small groups.
