This week you will need to update your eportfolios. 1. Go to your mathex title page and make a new link to a new page called 'Classroom Furniture Challenge'. 2. On the Classroom Furniture Challenge page, write up the following:
 * Eportfolios**:
 * what the challenge was
 * what your group did
 * a photograph or scan of your bird's eye view plan
 * a photograph or scan of your final product
 * a summary of the final report you gave to the class

Draw the translations for each of these in your books. You need to move them according to the co-ordinates given.
 * Translations**:

Rotational Symmetry
With Rotational Symmetry, the shape or image can be rotated and it still looks the same. How many ** matches ** there are as you go ** once around ** is called the ** Order **.

If you think of propeller blades it makes it easier. If a shape only matches itself **once** as you go around (ie it matches itself after one full rotation) there is really no symmetry at all, because the word "Symmetry" comes from //syn- **together**// and //metron **measure**,// and there can't be "together" if there is just one thing.) What is the rotational symmetry for each of these shapes? Now try these ones. ||

See if you can explain this:**
 * Just for fun.
