Introduction / This is a webquest designed for students to learn the concepts of complimentary and supplementary angles. This webquest allows students to use the internet to practice and learn the concept of complimentary and supplementary angles.

4
Learners / Grade 9 - Geometry or Interactive Math Program (IMP) Level 1 or 2 / Learners should know what a right angle looks like, and the symbol that represents a right angle / Learners should also know that a straight line forms a 180˚ angle / When teaching this lesson an easy way for students to remember the definitions is that ‘c’ comes before ‘s’ in the alphabet, and 90 comes before 180, therefore complementary angles add up to 90˚ and supplementary angles add up to 180˚ / Grade 9 - Geometry or Interactive Math Program (IMP) Level 1 or 2 / Learners should know what a right angle looks like, and the symbol that represents a right angle / Learners should also know that a straight line forms a 180˚ angle / When teaching this lesson an easy way for students to remember the definitions is that ‘c’ comes before ‘s’ in the alphabet, and 90 comes before 180, therefore complementary angles add up to 90˚ and supplementary angles add up to 180˚

Process / 1-2 class periods / Grouping should be at the discretion of the teacher, if students are put into groups, should be no more than 3 / Teacher must be aware of how to use the internet to implement this webquest / Students may run into problems applying the definition to word problems or other applications of the concepts / Therefore teachers must be prepared to give the students many practice problems / 1-2 class periods / Grouping should be at the discretion of the teacher, if students are put into groups, should be no more than 3 / Teacher must be aware of how to use the internet to implement this webquest / Students may run into problems applying the definition to word problems or other applications of the concepts / Therefore teachers must be prepared to give the students many practice problems

Evaluation / A teacher would know if this WebQuest was successful by the students completion of the in class examples after exploring the concepts on their own, and by how well the students complete their homework and apply the new concepts

Evaluation (continued) Homework Rubric 4 Exceeds the Standard 3 Meets the Standard 2 Nearly Meets the Standard 1 Below the Standard 0 No Evidence Every question is answered, including all work and/or explanations of how the answers were derived. Most questions are answered, including all work and/or explanations of how the answers were derived Some questions are answered. Work is only partially completed. Few questions are answered with little to no work included. Assignment not turned in. Work is organized and is easy to follow. Work is organized and can be followed. Work is somewhat organized and can be followed. Work has little organization and can not be followed. Corrections are made during homework review. Some corrections are made during homework review. No corrections are made before turning in. Work is turned in on time. Work is turned in a few days late Work is turned in a few weeks late

Conclusion / This WebQuest allows students to discover the new information and concepts on their own by using the internet / It is very important that students know the definition of complementary and supplementary angles, and it will help them to remember these definitions by discovering the information on their own, rather than having a teacher tell them the definitions and say you have to memorize these. / Once the students discover the new concepts, they will then have a chance to apply the new concepts, and if they have any questions they have the chance to ask them during the class time / It is important that students get a good grasp on these concepts for the next lesson, which would be on angles of parallel lines / This WebQuest allows students to discover the new information and concepts on their own by using the internet / It is very important that students know the definition of complementary and supplementary angles, and it will help them to remember these definitions by discovering the information on their own, rather than having a teacher tell them the definitions and say you have to memorize these. / Once the students discover the new concepts, they will then have a chance to apply the new concepts, and if they have any questions they have the chance to ask them during the class time / It is important that students get a good grasp on these concepts for the next lesson, which would be on angles of parallel lines

Introduction / You will be visiting two specific websites to discover the concepts of complementary and supplementary angles. The first website is a short movie explaining the definitions, and showing you examples of both types of angles. The second website will allow you to practice viewing angles and allows you to complete some problems right on the internet. Once you have a good grasp on the new concepts, you will complete some in-class examples applying these two concepts, and you will then complete a worksheet for homework giving you more practice with the concepts.

14
Task / Student Discovery Handout

15
Process / Students must first visit the two websites, read the information, and try some of the internet examples / Students must fill out the Student Discovery Handout as they are learning the material online / Once the students feel they have a good grasp on the material, they will complete the in-class examples / Students will then complete a worksheet for homework giving them more practice / Students must first visit the two websites, read the information, and try some of the internet examples / Students must fill out the Student Discovery Handout as they are learning the material online / Once the students feel they have a good grasp on the material, they will complete the in-class examples / Students will then complete a worksheet for homework giving them more practice

16
Conclusion / To conclude this lesson the teacher will go over your homework sheet the following day, and if there is still some confusion, there will be a few more in class examples to clear up the problems. Throughout the next few lessons, until there is a quiz on this topic, you will have at least one or two complimentary and supplementary angle problems on homework assignments.
