These activities are perfect for math rotations. This is a set of 14 cards you can place around the room for your students to solve. They include problems using the 100's chart, place value, word problems, addition and subtraction with regrouping, missing addends and fact families. Students can solve a few each day for two or 3 weeks leading up to the winter break. They are a great and fun way to review math skills learned. These could even be used as an assessment. They are geared for second grade, but third graders could do these too.
