Place value is one of those skills that help build true number sense. Giving students time to compare numbers and justify their answers increases their place value understanding. I have a set of 7 questions I like to use with my students. I call these questions the Sweet Seven. Students paste a copy of the question in their journals. Then, I provide them with three numbers to evaluate and answer in their journals. The numbers I select increase in difficulty as my students' skill level advances.
