The purpose of this lesson is a hands-on activity in which the students discover how to partition paper, while keeping the whole paper intact. This helps the students discover that a fraction is part of a whole without directly having them memorize definitions. Students work in groups to make predictions about how folding paper in certain ways will change the number of parts. I call it the doubling theory since it is folding paper in halves, then fourths, and finally eighths. Students have an opportunity to predict the pattern for the next fold. I called it the doubling theory. If students are ready they can also look at a theory for tripling and quadrupaling fractions in the same way. This lays the ground work for teaching equivalent fractions. This lesson will lead into Lesson 2 in which students need to use the same folded construction paper to complete a series of word problems.
