8th Grade Grid Enlargement Car drawings

For this lesson, students reviewed the grid enlargement process via three worksheets. (pics soon)
From there, they chose a photo of a car that they liked.
Instead of drawing a grid directly on the photo, I photocopied a grid on to transparency sheets.


The photo of the car was placed underneath and taped.


Students drew their own grid on another sheet of paper.  We used 1/2" x 1/2" measurements for their grid.  I didn't have paper large enough to make them bigger.  It actually worked out well.

To avoid overwhelming the kids with all of the detail of the car, I found it extremely helpful to have them start with the outline of the car.  To do this, we took a vis-a-vis marker and outlined the car.  This is nice because it can easily be wiped off and re-used next year.

After they had the outline drawn, they used the vis-a-vis again to outline large shapes.  As they continued they outlined more and more.  This was a huge help as it simplified the car for them.  
Shading was added in the end.



I left it up to the kids whether or not they wanted to erase the grid lines on their drawing.
