Understanding place value is an important part of the first grade curriculum. Students must understand the relationship between the tens and the ones place. In addition, they must understand the values of each place. Understanding how number work together is the building blocks for when students begin to add and subtract two digit numbers in the coming years. Place value provides students with the knowledge to utilize various strategies to identify, compare and add and subtract numbers. Most of the work can be used as supplemental work for your higher achieving students or intervention for your students who need more practice. I hope your students love the supplemental work as much as mine do!!
