Fusing Dots to Explore Place Value

Katelyn Gardepe, 5th grade, David Cox Elementary School

Final Unit(pdf)   Implementing Teaching Standards(pdf)


This unit focuses on fundamental place value concepts that many students lack coming into fifth grade. It is the intention of this unit to provide students not with a chart to memorize or an algorithm to follow, but with a deeper understanding of this concept. This unit utilizes the idea of Fusing Dots to help students understand the values of different place values and how they compare to each other, as well as the ideas behind regrouping and borrowing in addition and subtraction problems.
