Title: The Big Inch
Purpose: To develop a prop that will allow students to become more proficient in reading a tape measure.
Procedures: Each student needs to have a section of cardboard that is around 5 – 6 inches tall and a minimum of 13 inches in length. Take the length of posterboard and place a beginning mark that is 3 inches tall. This mark represents the beginning number, (such as 0 inches), on the ruler. Each mark should be placed ¾” apart. Varying heights are used to distinguish fractional measurements. Marks that represent 1/16” can be 1 inch tall, 1/8” marks an inch and a half, ¼” 2 inches tall, and ½” are represented by lines that are 2 ½” tall. At the end of the process, the student should have a magnified inch to aid them in discerning fractional measurements.
