There are two versions of this Pointillism worksheet.
The three eyes at the top of the page are good examples of what you want your students to create. Both worksheets ask students to create a scale of tone using dots. The first then asks students to draw and use pointillism to create an eye. The second, easier worksheet, asks students to add dots over a very faint image of an eye.
This could fit into a pointillism scheme of work (perhaps when looking at Seurat) or be useful as a homework or cover lesson.
