    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
