Engage your math students with this fun worksheet that combines geometry and marine life! Learners will plot, label, and connect ordered pairs on a coordinate plane, forming small habitats for sea creatures in the form of squares and rectangles. Once their sea sanctuaries are created, they'll then calculate the perimeter of each one.

Teaching perimeters on a coordinate plane to young kids involves explaining that a coordinate plane is a 2-dimensional space defined by an x-axis and a y-axis. Then, introduce the concept of a perimeter as the distance around the edge of a shape. After choosing a shape plotted on the coordinate plane, we add up the lengths of all the sides to find the perimeter.
