There is a task for every standard in the first grade math common core. I have created this set of math tasks to be used in many different ways. They could be used as pre-assessments or post assessments after teaching concepts. They could be used as a review at the end of the year. They could be used while teaching math concepts. Some of the tasks are skill based tasks and some tasks are problem based tasks (depends on the standard). While these are for first grade I think they could be used as a review for second grade or an extension for kindergarten.
