youcubed: Irrational Folding (9-12)

This activity is designed to give students the opportunity to explore, visualize, and create a representation of the relative lengths of the square roots from 1-10.

This is very important as the brain scientists we meet with tell us that we hold numbers in our brains on something like a number line. Do you see irrational numbers on a line when you think of them? Many times we learn about square roots without the context of the magnitude of the value of the number. Students will be challenged to make sense of the length of each of these square roots in relation to each other. Have students work together in groups on this task since they will need each of their experiences and ideas to come up with strategies for showing the different square roots on the origami paper.
