2nd grade students are expected to mentally find 10 and 100 more and less using place value principles. This set of 5 lesson plans creates a cohesive unit that will help your 2nd graders to build this understanding. Your students will use an abundance of hands-on materials along with place value drawings and place value charts in order to develop and demonstrate their understanding of how to compare numbers based on place value. This unit is included in a 2nd Grade Math Intervention Bundle! Sup
