The Harvard Graduate School of Education has assembled over 300 "innovative mathematics assessment tasks," and they can be viewed for free at this site. The tasks present the student with a scenario and ask a series of questions based on the information provided. They are separated into five different grade levels from kindergarten to twelfth grade, with one additional category for technology-based exercises. The tasks can also be searched by content area. Because this site is intended for teachers, solutions to the questions require a password that can only be obtained by ordering one of the related publications.
