Symmetry and Art

Grade 2 work sample
Symmetry is a fun part of mathematics that most students do not mind. Often it is a welcome break from numbers and what better topic to incorporate art.

This lesson was conducted over two 45 minute lessons (and I have also left it for relief teachers in previous years without issue).


Lesson 1

The first lesson revolves around talking and identifying what symmetry is. The samples shown were from a grade 2/3 class. Most had a good idea after a discussion that symmetry means the same but as a mirror image. Most had done the paint on paper and then fold in reception.



I then handed out the sheets which had half the butterfly on it. I found the image on the internet with a search. I didn't give the students any instruction on how to do the butterfly. I simply stated it need to be symmetrical. This freedom allowed me to access how to observe the problem solving skills as well.
Template I used. I inserted it onto a Word document.

Some students kept it simple, some went all out. This was why I also asked that they include three (3) sentences explaining why it was symmetrical. I didn't get that from all - lots chose instead to do a description but it was a learning curve for me too and made for interesting reading.

Lesson 2

This was the finishing off time and writing part. At this point I remember several students realising that they hadn't mirrored their stripes. As they were able to pick this up for themselves though made for all the better learning.

Observation

Watching the problem solving skills was interesting. The top example was achieved as they girl decided to backwards-fold the paper and trace the edge of the butterfly by holding the page up on a window. She did this first and then decided on her design.

The example to the left was done purely by hand. He chose a daring and complicated design but worked hard to have it completed on time. The student had a huge sense of pride as he struggled in literacy which had impacted his confidence greatly. In addition he was the only student who attempted to use the vocabulary of symmetry/symmetrical. All his work was completed independently.

Grade 2 student
The third example was from a girl who also used the fold and trace method. She used it at the start to get the shape and then again to do her pattern work. Her design was very simple, it is effective, but i would say that it was very "safe". This student was capable of challenging herself a lot more but had been taught by teachers previously who though getting the work done was enough. 


Overall, I was pleased that the work was finished, predominately, on time. The work also looked great being on display for acquaintance night.
