Notes
The teacher will introduce the students to the Pythagoras
theorem. The teacher will draw a few different triangles and
ask the students what is special about the triangles which they
can use the Pythagoras theorem on (right angle)
The teacher uses squares to start
introducing triangles to the students. The
students can put these together to make
rectangles. The students can see there
will be a triangle in between the
rectangles.
The teacher tells the students that right angle triangles are the
only type of triangle where one can use the Pythagoras
theorem. The teacher can use squares as an activity to see that
these triangles between the squares are right angle triangles
The teacher asks the students what are
special about the triangles. If the
students have some prior knowledge,
they might know otherwise the teacher
will tell the students that there triangles
are right angled
The teacher introduces the students to the names of the
different sides on the triangle The students start to learn
the names of the sides
The teacher will ask the students what
they think the longest side of the triangle
is first. The students should answer the
diagonal side. The teacher will then ask
the students what they think the shortest
side is. Finally the teacher will ask the
students what they think the other side
is.
The teacher will introduce the theorem of Pythagoras
After explaining the lengths of each side,
the teacher will start explaining the
Pythagoras rule. The rule is that the
longest is side the sum of the shortest
and middle squared then square rooted
The teacher will explain to the students how they will find the The teacher will go through a few
length of a side. The teacher will give a few examples find each examples with the students and hope
side
that they start to understand. Once most
of the class understands, the teacher can
move on
The teacher will ask the students to open their textbooks and
do a few example questions. The example questions will be
from the workbook or from a worksheet
The teacher will give the students
questions from the workbook or a
worksheet which they can start working
on. The teacher will also start helping the
students who didn’t understand the first
time.
