In many cases the tools and materials are unfamiliar or specific enough to warrant photographs or highly detailed drawings. If more generic or familiar tools and materials are all that's wanted, drawings may suffice. Mental procedures, such as math operations, must be represented symbolically by formulae or other concept diagrams, in which case learners need to see the symbol system or conceptual "ingredients" if they are not already familiar with them.

First, enter a brief description of your visual (e.g., Tools needed for shearing sheep). Then choose an appropriate type of representation to show the tools or materials. When you're satisfied select NEXT.
