A fun way to learn geometry is through handwork. Crocheting basic shapes leads to discussions and observations about numbers, patterns, fractions, and so much more!
We started with some lovely alpaca yarn that came straight from Upstream Alpacas. They handspun and dyed the yarns from their own alpacas.
Our 5th grader Wilson then wound each skein into a ball.
We played with geoblocks, figuring out which shapes can be used to form other shapes, such as using 6 triangles to make a hexagon.
Wilson then learned how to crochet granny triangles. He had made granny squares before, so he understood the concept of starting with a circle to create another shape.
One thing that we learned, is that the triangle points wanted to curve. Wilson made sure to single crochet three times into each corner.
The triangles were sewn up with leftover yarn.
The 6 triangles, when sewn together, curled up a bit, looking like a circle.
The end result is a beautiful, rainbow hexagon! We use it in our homeschooling bookcase and place special calendar gnomes on top.
