Chritsmas snowflakes for the gymkhana Christmas tree

SNOWFLAKES

Rotational symmetry
6-pointed Paper Snowflakes instructions. This task will be a good example of polygons and rotational symmetry.

Discovering Kirigami. Geometry for Christmas

CHRISTMAS TREES
Axial symmetry
We are going to construct a pop-up Christmas Tree using another Japanese technique named Kirigami. It will be a good example of POSITIVE SPACE and NEGATIVE SPACE.

Here you will find the template to be downloaded:

Instructions. By Robert Sabuda.

We are going to use color paper and we will use them as hanging trees.

Creating symmetries

You have been given one Halloween character to complete the missing part. You can not trace or fold it, nor measure more than 15 or 20 points (by using the drafting compass or a ruler) in order to get the mirror image by symmetry.

Symmetry with IT

Line symmetry - Reflection symmetry - Mirror symmetry

• Reflection.
• Symmetry haelmedia activity.
• SymFace. It lets you see how your face would look if it was perfectly symmetrical. You will need a picture of your face (better), or just use one provided for this software. Very funny!.
• How many lines of symmetry? Game.
• Axis of simmetry. Test with score. By Khan Academy.
• Reflected symmetry.
• Symnmetrical and asymmetrical balance.
• Line symmetry. A. Learner.

Multiple line symmetry

• Snowflake Creation. Multiple line symmetry.
• SymmeToy. You can download it (it's free). It is a program to create paint patterns, symmetry roses, tessellated art and symmetrically decorated 3D polyhedron models.

Rotational symmetry

• Rotational symmetry. Orders... Fun! And then... Enjoy with Symmetry Artist.
• Point symmetry. (= rotational symmetry order 2)
• Rotation. BBC resource.
• Rotation. A. Learner.

A REVIEW:

• Symmetry of flat shapes:

Curiosities:

• Ambigrams (Images that can be viewed upside down or right side up):
