Trace the outline of each leaf on inch grid graph paper. Label the outline of each leaf with its identification number and letter. This should be written neatly below the outline of each leaf. Estimate the area of each leaf by counting the number of squares within its outline. Record the estimated surface area of the leaves on the data chart.
Partners work together to use string to outline each leaf.
The length of the string should then be measured. This will give the perimeter of each leaf. Record the perimeter of each leaf on the data chart. Work together to shape the string into a rectangular shape. One partner will use 4 fingers as corners of the rectangle.
