Drawing the Images
For this lesson you need an image that has been divided into 20 parts
This art lesson is a group project for up to 20 students which starts as a project on color and ends as a large scale portrait.
To prepare the images for this lesson the teacher or organiser has to produce a drawing and divide it into 20 square sections - at least one for each participant. This must be done in advance so that the identity of the portrait is hidden from the students to avoid spoiling the surprise 'reveal' at the end of the project.
Download Our Ready Made Images
You can download the images for this lesson.
We are aware that there is a lot to prepare for this lesson and that this could be a problem for teachers or organizers who do not have much preparation time. To assist you we have supplied complete sets of images that have already been divided and cut into 20 individual square sections.
You can download the images for this demonstration as a .PDF file which you may print on A3 or A4 sheets for use with your class or group. There are more examples to choose from in our sets of images at the bottom of the page.
How to Create a Set of Your Own Images
If you wish to personalize this lesson by creating a set of your own images we have outlined the various steps to follow below:
Step 1: Start with a two-tone drawing whose proportions are 4x5 units
You start the project by drawing a head in two contrasting tones of light and dark. The proportions of this head should be 4 x 5 units. For our example we have drawn the head of Batman.
Step 2: Divide the drawing into 20 square sections.
Next, you should draw a 4x5 grid over the image to divide the drawing into 20 square sections. You need to number each square so that you know how to reassemble the image at the end of the project.
NOTE: It is best to do the numbering on the back of the drawing to avoid obscuring the image.
Step 3: Cut the image into 20 separate sections.
Now you should cut along the lines of the grid to divide the image into 20 separate sections - at least one for each participant.
Step 4: Draw a 4x4 grid on each of the 20 sections.
Finally, each section should be divided by a 4x4 grid which splits up the individual shapes into smaller increments ready for painting.
Changing the Scale of the Sections
Step 5: You can also use the grid as a guide to help you change the scale of the sections.
Not only does the 4x4 grid break up the section into smaller increments for painting, but it also makes it easy to scale up each section if you want to create a larger image. It is quite a simple task to sketch the image box by box using the grid as a guide.
The size of the sections will determine the size of the overall image. For example, if each individual section is 12"x12", the overall image will be 5'x4' when all the sections are assembled together at the end of the project.
