The “Chrysanthos Trigeod Colour Wheel Puzzle” lesson plans contain nine lessons aimed at kindergarten students. The material covers three key areas an introduction to the colour wheel, mathematics focus and language focus.

Credit for the work is attributed to Ms. Rose Marcelli RECE, OCT a designated early childhood educator and Ontario certified teacher. The lesson plans have been implemented in a full-day kindergarten classroom in Ontario. 


Lesson I – Students manipulate the Trigeod shapes to create images in 2D and 3D. The goal is to create something they imagine.

Lesson II – Students go on a scavenger hunt collecting and classify coloured shapes according to their colour relative to the colour wheel.

Lesson III – Students perform experiments with colour by identifying primary colours then experimenting with mixing colours to create other colours.


Lesson IV – Students learn to represent and demonstrate their understanding of numbers 1 to 10 using the Trigeod shapes.

Lesson V – Students sort, classify and compare objects based on colour.

Lesson VI – Students identify, reproduce and extend repeating patterns through investigation using the Trigeod shape.

Lesson VII – Students learn to recognise quantities of objects without counting and concepts of addition and subtraction using the Trigeod shapes as manipulatives.


Lesson VIII – Students learn to represent the letter of the alphabet using the Trigeod shapes.

Lesson IX – Students learn to label their designs created in Lesson I with simple language.

The “Chrysanthos Colour Wheel Teachers Manual” contains three lesson plans for teachers to use to teach students about the colour wheel, colour theory and about shapes.

Lesson I – Students learn how to mix primary colours to create secondary and tertiary colours. They use the colours they create to paint the Trigeod shapes and then create the colour wheel.

Lesson II– Students are introduced to colour theory including warm and cool colours, tints, tones and shades and colour schemes. Each section is supported by internet based graphical and pictorial examples of concepts to reinforce learning. Discussion and assessment of understanding is performed at the end of section.

Lesson III – Students learn more about the Trigeod. They learn that this is an organic shape and use it to create 2D and 3D designs that resemble “biomorphs”. They also learn about other designs that can be created with the shape while discussing and interacting with each other in some of the design processes. At the end of the lesson, students are asked to create a 2D design on paper using the the colour wheel and then colour it in using one of the colour schemes they have learned about previously.
