Flextangle and Kaleidocycle Origami Angles Investigation - Classroom Activity

This angles-focused flextangle (kaleidocycle) template turns geometry into a hands-on classroom origami activity.

Students measure and classify angles, calculate the internal angle sum of shapes, and explore how these rules play out within the foldable design.

This teacher resource includes:

• 1 x Colour Template: teacher demonstration (pre-coloured for ease)
• 1 x Line Art Template: student activity (measure angles)
• 1 x Mathematics Task Card: instructions and investigation

Find the Flextangle bundle here - enjoy a range of colourful and fun flextangle templates.

The classroom activity includes a line and shape-based template, giving students the opportunity to work with angle types, polygons, and geometric properties in a tangible way.

Once constructed, the flextangle invites deeper observation. Students can rotate the structure and investigate whether the angle relationships they measured — such as complementary, supplementary, or vertically opposite angles — still hold true.

This moving origami model encourages reasoning, discussion, and discovery, making mathematical origami a memorable way to connect theory with practice.
