Symmetry

Symmetry

Learning Intention:

We are learning to identify line and rotational symmetry

Success Criteria:

– I am able to visualise a polygon or object being rotated (rotational symmetry)

– I am able to visualise a polygon or object being divided into equal parts (line symmetry)

– I can find lines of symmetry and draw them

– I can rotate polygons

– I can demonstrate line and rotational symmetry

 

BIG QUESTION NO1:

What is a polygon?

 

ploygons

 

polygon: a plane figure with at least three straight sides and angles, and typically five or more.

 

BIG QUESTION NO2:

What is symmetry? We want to look at 2 types of symmetry.

Line symmetry:

7a_sub1

Rotational symmetry:

symmet03

 

Activity:

Draw 5 Shapes that have line symmetry and 5 shapes that have rotational symmetry.

Data Collection

How much data is round!

We are looking our fitness and combining this with our mathematics focus of data. We have been doing 1 minute exercises and recording the data.
