Use A Chair To Teach Math Objectives The student will learn some basic operations of math by measuring a chair. Materials needed: Folding chair or desk chair paper desk graph paper tape measure a box Plan: Place a folding chair or desk chair on top of a desk so all students can see. Have students measure the various parts of a chair. (back, legs, seat, height, width, etc.) All students should make a list of these measurements for their personal use later on. After measuring the chair, ask the class for answers to questions like the following: a. What size box would it take to mail the chair? b. Could two chairs fit in the same box? c. How many chairs could fit in this room? d. What area of space does the chair occupy per floor space? e. These questions should also serve to motivate students to think up questions of their own. Give each student a sheet of graph paper and pencil and ask them to plan a drawing of the chair. Then give them a second piece of graph paper and ask them to make a second drawing. This time half the size of the first one. How many chair lengths in one km? Solicit additional math questions from the students. Allow time for the students to discuss problems that exist; for example: "It depends which way the chair is turned!" Have students use the measurement to find answers to the question asked and list the operation used. Make sure the students make or find a box for the chairs to fit in for mailing.
