Colour Theory with Found Objects

After the success I had with my grade 5s and their "human" colour wheels, I decided to try a similar approach with my grade 6s.

This time I challenged them to find objects in the classroom that fit the criteria.

First I asked for three students who thought they knew the primary colours.  They then had to search the room for the colours, bring them back to the front and wait for confirmation by the other students.

Here are the primary results.


Next, three more students searched for secondary colours.  One of the students volunteered herself.


The whole class was challenged to find warm coloured objects.  Hectic but enthusiastic results.

Once again, everyone was involved in the search for cool colours.
Finally we created a colour wheel.
The primary coloured objects were placed first, then the secondary ones.
We talked about tertiary colours and students searched for them.
There was much discussion as students moved objects around to better balance the wheel.
Once again, students were able to very quickly complete their colour theory sheets.
This method would be great at any grade level.

Mona Lisa...You've Changed

Recently my students examined da Vinci's Mona Lisa.

We discussed her pose, clothing, location and of course, her famous expression.

They were then challenged to create their own versions using pencil crayons and/or markers. 

Some of  the results are below.  Check out the facial expressions!


Colour Wheel with a Twist

I decided to take a different approach to reviewing the colour wheel with my grade 5 students today.  I used them. 
Fingers were crossed that they would show up wearing a variety of colours and except for being a little off on the violet, it turned out well.
I began by asking them to stand if they were wearing a primary colour.  We talked about what made a colour primary.

Next those wearing a secondary colour stood, they were asked which colours were used to make it.

Students then arranged themselves in warm and cool combinations.
We talked about tonal values and lined up legs to show different shades and tints.  They knew how to use black or white to change the colour.
Students wearing green also wanted their picture taken.  We discussed how adding more blue or yellow could change the colour.
At first students did not quite understand the concept of complementary colours being opposites.
I briefly did an afterimage exercise with them. 
First I had them open their agendas to a white page, then I had them place their pencil crayon boxes on it.  I asked them to focus without staring hard on the yellow on the box.  I timed them for about 1 1/2 to 2 minutes, then had them pull away the box while still looking at the page. 
 Ooos and ahhs were heard around the room as they briefly saw violet on the page.  One student was so excited, he called another one over to "see" the colour he saw.  I related the effect of the afterimage to film negatives.  You know you are getting old when not all knew what they were! 
Afterwards, they were able to name all the complementary combinations.
Finally students created a "human" colour wheel.  One of them pointed out how they were lined up with their opposite.  Success!
To end the project, I handed out a colour assignment sheet.  They very quickly completed and correctly labelled it with little help from me.
I will definitely do this again in the future.
