Variety, when differentiating the product, means varying the format of the products students are expected to develop throughout the school year or term. It is also possible to have different students develop products in different formats for the same content.

Products may be classified according to their form of expression. Roberts & Inman^[90]provide 5 categories: kinesthetic, verbal (oral), visual, written, and technological. Students need opportunities and support to develop the skills needed to create effective products in all of these categories.

High ability students should be expected to learn to express their thoughts and ideas through many forms of expression, media and technologies. These experiences will enable them to communicate effectively with members of professional communities as well as peers, parents, and teachers.
