7.5 The student will formulate rules for and solve practical problems involving basic operations (addition, subtraction, multiplication, and division) with integers.

Hands-On Activities

  • Regentsprep Here are notes on adding, subtracting, multiplying, and dividing integers. There are practice problems at the end of each lesson.
  • Activity 2
  • Activity 3

Other Web Sites

  • JLab Reviews the rules for adding integers and complete a few practice problems.
  • ExploreLearning Students can self-enroll but need to get the enrollment code from their teachers. Teachers have to assign the Adding and Subtracting Integers to their classes.
  • Larson´s Software This is server-based software and students need to be enrolled by their teachers. Click on the Integers, then click on Multiplying Integers.

Lesson 2-3: Solving Practical Problems and
                    Formulating Integer Rules


Addition and Subtraction
Enter different integers for the first (f) and second (s) variables. Look for patterns then develop rules for adding and subtracting integers.

 Multiplication and Division
Enter different integers for the first (f) and second (s) variables. Look for patterns then develop rules for multipying and dividing integers.
