7/29/2019 Angles Lesson 1
1/3
LESSON PLAN
Year: Year 5Curriculum
Area:Mathematics
Date: Monday 13th May 2013 Time Period: 60 Minutes
Specific Lesson Learning Goals Students will be able to:
Define an angle
Identify an acute angle
Identify an obtuse angle
Identify a right angle
Identify the units by which an angle is measured
Students Prior Knowledge:
This is the students first lesson on angles. Students have
previously studied shapes.
Preparation:
Whiteboard
Whiteboard markers
Information:
Definition: The space between two intersecting lines between the
point where they meet
Intersecting line lines that meet at one point
Types of angles: acute, obtuse, right, reflex
Right angle an angle of 90 degrees. Two lines that make an L
shape
Acute angle an angle that is smaller than a right angle
Obtuse angle an angle that is greater than a right angle but
smaller than a straight line
Reflex angle an angle that is greater than a straight line

Lesson Progression
Gather the students at their desks and ask for quiet and
attention
Let the students know that we are going to be looking at
angles
Ask the students what angles are start a discussion within the
class
Write the definition of an angle on the whiteboard
Break down the definition and explain each part of it so that
the students
understand
Explain to the students that there are different types of
angles
Draw the different types of angles on the whiteboard
Label and define each of the different types of angles
Explain to the students how we identify or mark angles (curve
over the
intersection)
Draw a 8 angles on the whiteboard and ask for volunteers to name
the types
of angles
Ask the students to open their Maths books to the next new page,
rule up,
date and title
Explain to the students that they need to use their rulers and
pencils to draw
a right angle
Ask the students to draw three acute angles, three obtuse
angles, and three
reflex angles
Ask the students to label their angles with the correct name
Tell the students to get started
Walk around the classroom speaking with the students about their
angles andmaking corrections or advising where necessary
Ask the students to pack away their Maths books
Ask a volunteer to hand out the work sheets
Ask the students to name each of the types of angles on their
worksheet
Ask a volunteer to collect the completed worksheets
Gather the students in a circle at the back of the room
Ask the students to make a right angle with their arms; then an
acute angle;
then an obtuse angle
Ask the students in turn to make angles with their arms for the
other studentsto guess what type of angle it is
Congratulate the students on a great lesson and prepare them for
the start of
the next lesson

Informal Assessment of Student Outcomes
What will you assess?
Define an angle
Identify an acute angle Identify an obtuse angle
Identify a right angle
Identify the units by which an angle is
measured
How will you assess? What evidence will youcollect?
Look at and correct the drawn angles in
the students Mathematics books
Collect and mark the collected worksheets
Return the marked worksheets to the
students
