This printable teacher resource includes purposeful teacher activities designed to support effective teaching and student engagement. As part of the Gifted and Talented Teacher collection of teaching resources, it provides ready-to-use activities that save time and support meaningful learning.

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

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.
