This is a review activity I created. It would be good used in small group, as formative assessment, or as homework. It covers identifying the place value and value of specific digits in three digit numbers. It also covers writing the standard form of a number based on the base ten blocks given. There is a section for comparing numbers and one for 10 more, 10 less, 100 more, and 100 less. It was designed for 2nd grade, but could be used for stronger first or as a review for 3rd grade.
