Can you think of an quicker way to translate the shape?

Translate the shapes as follows:
Red shape: 3 down
Blue shape: 4 left, 2 down
Green: 4 right, 2 up
The translated shapes form a letter. Which letter is it?

Translate the shapes as follows:
Red shape: 3 down
Blue shape: 4 left, 2 down
Green: 4 right, 2 up
(Extn: how are the numbers connected to the translation?)
The translated shapes form a letter. Which letter is it?

Translate the shapes as follows:
Red shape: 2 right, 2 down
Blue shape: 3 left
Green: 1 left, 2 up
(Extn:
How are the numbers connected to the translation?)

Now it’s your turn…
• On your worksheet, translate every shape in by the translation attached to it.
• Use tracing paper to help you.
• All the shapes should fit together to form a word.
• Draw in pencil in case you make any mistakes.
• Count carefully!

Rectangle abcd does a translation of 6 right, 3 down
What are the co-ordinates of
a’ b’ c’ and d’ ?
a’ = (-1, -1)
b’ = (2, -1)
c’ = (2, 4)
d’ = (-1, 4)
