Geometry

:

Symmetry

Understand that a figure does not change in a symmetrical rotation, the only change is positional.

###### Supporting targets:

###### 1:

Identify the center point of a shape.

###### 2:

Rotate a given figure at 90-degree intervals around its center point.

###### 3:

Understand that a shape has rotational symmetry if it can be turned less than 360 degrees and look exactly like the original.

###### 4:

###### 5:

###### Grade:

4th

###### Vocabulary:

Center, Rotational Symmetry, Rotate

Activities:

Students

- discussed and sorted shapes by whether they had rotational symmetry or not
- drew shapes or pictures that have rotational symmetry
- designed a snowflake or circle to show rotational symmetry

### Home Exploration

###### Challenge Problem:

Can you find any objects in your home that have rotational symmetry?

###### Challenge Data:

###### Guiding Questions:

You can rotate the objects to check if they look the same at any point when they are rotated up to 360 degrees.

###### Challenge Answer:
