Essential question: What is infinity?
Unit Summary: Students will examine the essential question, “What is infinity?” The students will use a strand of a cooked spaghetti noodle to help them visualize the concept. Each student will fold the strand of spaghetti in half and make a cut to divide it into two equal pieces. They will measure the half and record its length to the nearest one-eighth inch on their data table. Then they will repeat the step, cutting the half into a half and measuring its length until they can no longer measure the strand. They will cut the remaining piece as small as possible until they can no longer make a cut. After observing their data, the students will discuss infinity and state their own idea about the concept of infinity.
1. Have the students write a story that includes number sentences with fractions and the word infinity.
2. Look up the symbol for pi and write down what it represents. Then look up this site: http://www.piday.org/million.php. Have the students write several lines of pi’s value.
3. After reading the book, have the students write a short description of the main idea of the book. Use the phrase, “I am a mathematician. I know that _________.”
