Lesson Plan : Find Product/Quotient of Integers
Teacher Name: | Ms. C. Williams |
Grade: | Grade 7-8 |
Subject: | Math |
Topic: | Finding the product and quotient of integers |
Content: | The product or quotient of two integers: is positive when both integers are positive or both are negative. The product or quotient of two integers is negative when one integer is positive and the other is negative. |
Goals: | Students will develop strategies for multiplying and dividing integers. |
Objectives: | The student will: 12.1 Represent integers on the number line. 12.2 Model situations with integers. 12.3 Compare integers using <, =, and > symbols. 12.4 Develop strategies for adding, subtracting, multiplying, and dividing integers. 12.5 Use integers to solve problems. 12.6 Find inverses for given integers. |
Materials: | Overhead projector, computer w/projector |
Introduction: | The Party in Mathland. This little story is designed to help students remember the rules of multiplying and dividing integers. Students will use be given a study guide for their math notebooks to use as a reference. |
Development: | Students will view the rules of multiplication and division of positive and negative numbers using the website "Amby's.com" |
Practice: | The teacher will use the website's practice section to practice as a class, completing the problems. Students will work with a partner to complete the practice problems. The teacher will circulate and monitor student's progress and answer any questions students may have. |
Accommodations: | 1. Students will work with a partner during class time. |
Checking For Understanding: | Students will complete the following two problems to check for their understanding of multiplying and dividing positive and negative numbers. If Roger is losing $12 each day, how much would he loose in 23 days? Formulate the problem (-12)*23) Process: Multiply the numbers and get the solution -276. Since it is a negative number multiplied by a negative number, the answer is negative. Solution: Roger would loose $276.00. Jeremy has a debt of $23,000. He pays $245 each month. How many months until his debt is paid off? Formulate the problem: -23,000/-245 Process: Divide the numbers and get the solution 93.88. Since the answer is a negative number divided by a negative number, the answer is positive. Solution: 94 months. If the students have difficulty, addition examples will be provided. |
Closure: | Restate the objectives and review problems from the practice problems. |
Evaluation: | Students will be given a quiz (10 problems) to access their understanding of the concepts being taught. Students will be administered a paper and pencil test. |
