“The BIG Inch” is an idea for helping students read fractional measurements
Title – The BIG Inch
By – Josh Murdock
Primary Subject – Math
Grade Level – 6-7
Materials: Posterboard or cardboard, rulers
Time: 1 hour
Objective: To create a prop that will aid the student in learning the fractional units of a tape measure to 1/16th.
Procedures: Each student needs to have a section of cardboard that is around a minimum of 5 – 6 inches tall and 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 Ã‚Â¾ inches apart. Varying heights are used to distinguish fractional measurements. Marks that represent 1/16th of an inch can be 1 inch tall, 1/8th of an inch marks an inch and a half, Ã‚Â¼ of an inch equals 2 inches tall, and one-half of an inch is represented by lines that are 2 Ã‚Â½ inches tall. At the end of the process, the student should have a magnified inch to aid them in reading fractional measurements.
