You don't need to follow a strict grading rubric, just write a short paragraph evaluating each presentation on two broad aspects: content and style. In terms of content, evaluate whether the presentation effectively addresses the objectives(whether they invested correctly/Portfolio diversity is correct or not) of the assignment and include all necessary information/materials/analysis to provide a comfortable understanding of the topic. In terms of style, evaluate whether the slides are well organized and sequenced to be able to facilitate a smooth "presentation", and whether the use of text, animation, graphics, audio/videos etc. are effective and attractive. Then assign a summary score to each presentation on a scale of 1 to 5 (5 is the highest; fractional scores e.g. 4.5 etc. may be given).
