Third Grade Module 4:

In module 4, students recognize area as an attribute of two-dimensional regions. They measure the area of a shape by finding the total number of same-sized square units required to cover the shape without gaps or overlaps. Students understand that rectangular arrays can be decomposed into identical rows or identical columns. They connect the number of rows and columns to the side lengths and then connect area to multiplication. Students use multiplication to determine the area of a rectangle and apply area concepts and strategies to mathematical and real-world problems.
