I made this monster themed math pack to help my students review some of the important concepts and skills taught during our math lessons throughout the year. This packet was designed based on the Common Core Standards for first graders. In my classroom, I use the monster math pages as morning work or as a daily review or warm up during math time. The problems are designed to review and reinforce specific mathematical concepts and skills. My first grade students start using the monster math pages mid-way through the year. There are 20 different student pages included in this packet. This packet would also be appropriate to reinforce and review mathematical concepts at the beginning of second grade.
