LESSON PLAN ON ANGLES
Teacher Name: Fariha Arshad Class: 8th Section: A+B
Subject: Mathematics Duration: 35min Date: 1st April, 2019
Week: First of April
Unit name: Introduction to Angles
Students’ Learning Outcomes
Students will learn the characteristics of 4 different angles and use this information to identify
and draw the angles.
Will use facts about right, acute, obtuse, and straight angles in a multi-step problem to write and
solve simple equations for an unknown angle in a figure.
Introduction/Teacher information
Tell students that today they will be learning about 4 different types of angles.
Begin your presentation with a right angle. Demonstrate how a right angle measures 90 degrees
with a protractor. Ask students to name some items in the room with a right angle. Example: the
corner of a book, the corner on the window.
Introduce the other angles by referring to and comparing them to the right angle.
Tell students that an acute angle is smaller than a right angle, or under 90 degrees, and that
an obtuse angle is wider than a right angle, or greater than 90 degrees.
Tell students that when an angle measures exactly 180 degrees, it just looks like a straight line
and is referred to as a straight angle.
Create an anchor chart with the 4 angles that lists their characteristics. Ask the students to help
you create a T-chart on the whiteboard or the document camera and write down how the angles
are similar and how they are different.
Discuss and check for understanding.
Material / Resources
White Board, Board marker, Duster, Teacher diary , Book, Model made by teacher.
Recap:
Check the previous knowledge of students by questioning:
Define Angles
What is the purpose of an angle
Methodology
Activity based method
Main Activity:
1-This is an acute angle. We know that acute angles are smaller than 90°.
2-This is an obtuse angle. We know that obtuse angles are bigger than 90°.
Assessment
During all activities informally assess the mastery of the math concepts you are teaching.
As an exit ticket, ask students to take out a piece of notebook paper and then name each
of the 4 angles and ask them to draw and label the angles.
Collect exit slips and posters.
Review and return exit slips to students and note any students who may need further
review.
C.W: Lesson on angles will be given to the students.
H.W: Draw the following angles using a protractor. Identify the type of angle you drew.
a. 75° b. 160° c. 90°
