4th grade reviewing SHAPE, LINE, and PATTERN

My students, once again had a blast doing this project.  First we reviewed geometric shapes by discussing what makes a shape geometric.  Then we sprayed them with water and watched them bleed into organic shapes.  Using marker we enhanced the new organic shape, then filled in our background with line pattern (after reviewing the 5 categories of line).  Finally. We added a little touch of complementary color for emphasis.
