This is aligned with the following California State Standards:
Recognize attributes or characteristics of an object, such as color, orientation, length, width, and weight.
Recognize and explain measurable (e.g., height, depth, diameter, weight) and non-measurable (e.g., color or orientation) attribute values.
Communicate understanding that length is the measure along a side of a shape or object and perimeter is the measure around a shape or object, beginning and ending at the same point, and without any overlap.
Calculate the perimeter of a shape by adding the measures of all the sides. Calculate the perimeter of a rectangle drawn on a grid paper by counting the unit squares contained within the boundary of the shape.
Determine the perimeter of a square or rectangle drawn on a graph paper using the x- and y-coordinates of the vertices.
