This is one of my favourite activities from our ExperiSense NZ homeschool box that explores maths through art.
It’s a way of engaging with Venn diagrams; traditionally, these are used to show the overlap of sets or categories of information but this wonderful visual explanation of them explores the ways that colours mix and overlap. It’s an organic process, reminiscent of the natural world, that removes language barriers and can appeal to visual learners.
It’s also beautiful, fun, and sensory. It can be used to encourage flexibility and demonstrate how things can be the same-but-different by experimenting with different colour mediums.
A great book to pair with this is Ish by Peter H. Reynolds to demonstrate that perfection in art is not necessary (for those that worry about colouring outside the lines).
The Dot, also by Peter H. Reynolds, which shows how an entire modern art collection can grow from something as simple as a circle.
