This is packet includes direct instruction dialogue, lessons for rounding to tens from 0-100. My first packet covers 0-10 and is included in this packet as well. Also included in this packet is a Core Curriculum Activity to provide your students with a higher level thinking objective. If you are looking for a hands-on activity to help you teach rounding, this is it. When I used the lesson with my small group of 4th grade students, it was extremely successful.
