Maths warm up!
LO: to practise converting units of measure.
Answers
LO: to use reflection.
In order to answers these types of question, we will have to
recap two key skills
Key skill 1:to be able to
recognise whether a
shape has been
reflected accurately
Key skill 2 - to reflect a
shape in a mirror line
Let's remind ourselves of some important points.
What is this called?
What equipment can we
use to help us to find and
draw reflection?
Let's remind ourselves of some important points.
This is the mirror line.
We can use a mirror to
check our answers.
Watch MeKey skill 1:to be able to recognise whether a
shape has been reflected accurately
Has this shape been correctly
reflected in the mirror line?
What can we do to help us
check?
Watch MeKey skill 1:to be able to recognise
whether a shape has been reflected
accurately
This shape has been
correctly reflected. We can
use the squares to help us to
check that the shape is in the
correct position.
Key skill 1:to be able to recognise whether
a shape has been reflected accurately
Has this shape been correctly reflected in the mirror line?
How do you know?
Key skill 1:to be able to recognise whether
a shape has been reflected accurately
This shape has not been reflected correctly. We now this
because it should appear opposite in the mirror line.
This is where the reflection should appear.
Key skill 1:to be able to recognise whether
a shape has been reflected accurately
Has this shape been correctly reflected in the mirror line?
Be ready to explain how
you know!
Key skill 1:to be able to recognise whether
a shape has been reflected accurately
Has this shape been correctly reflected in the mirror line?
This shape is correctly
reflected. I know this
because the vertices are an
equal distance to the mirror
line.
This shape is incorrectly
reflected. I know this
because the vertices are not
an equal distance to the
mirror line.

Key skill 2 - to reflect a shape and co-
ordinates in a mirror line
Reflect the shape in the mirror line.
I must carefully count the squares to ensure that the
vertices are the correct distance from the mirror line.
Watch Me
Key skill 2 - to reflect a shape and co-
ordinates in a mirror line
Reflect the shape in the mirror line.
Key skill 2 - to reflect a shape and co-
ordinates in a mirror line
Reflect the points in the mirror line.
We can transfer our
skills for reflecting
shapes to using co-
ordinates. We must
ensure that we count the
squares carefully to
ensure that the points
are an equal distance
from the mirror line.
Key skill 2 - to reflect a shape and co-
ordinates in a mirror line
Reflect the points in the mirror line.

practise.
