Students make their own angle-fold pop-ups and get them to work. Like parallel-folds, angle-folds may be symmetric or asymmetric.
For each student:
1. Using the Angle-fold Template
: Show students how to assemble a single angle-fold pop-up
using the template. They use it to find out how to create more or less movement
2. Assemble it unfolded
- Outcome: The flag moves the most when it is attached along the fold line. The longer the flag, the more it will move.
. To find out more about how an angle-fold pop-up works, students should next learn how to tape an unfolded triangle into the template
. They predict what will happen and then try this at different angles from the gutter.
3. Asymmetric angle-folds.
- Outcome: If the pop-up is taped in unfolded, it will make a fold when you close the book. The closer the pop-up is taped to the gutter, the taller it will stand when the book is open.
An angle-fold can be attached at different angles on either side of the gutter. See a video showing how to make an asymmetric angle-fold.
Students predict what will happen when they close and the open the book.
- Outcome: The fold line in an asymmetric angle-fold will tilt toward the side that is furthest from the gutter.
