In BC’s New Curriculum Metis Finger Weaving is suggested as a way of incorporating Indigenous Ways of Learning into Grade 2 math learning outcomes to do with patterning. I got to facilitate this at Queen Elizabeth School, where I teach.
I made a demo to teach them. I have tried it with two colours and 5 colours now. I think the goal behind the suggestion of using 5 colours is that you can create a chart and more easily prevent strands from crossing when you are arranging them. But I actually had more success with two colours. This may also have been because we chose a more authentic style of teaching by doing one on one and small group instruction after demonstrating it for the whole class.
