Join in this ongoing research. Build squares on the sides of a triangle, join the outer vertices forming hexagons, build further rings of squares and quadrilaterals, investigate.
Join some regular octahedra, face touching face and one vertex of each meeting at a point. How many octahedra can you fit around this point?
Interior angles can help us to work out which polygons will tessellate. Can we use similar ideas to predict which polygons combine to create semi-regular solids?
Can you use LOGO to create this star pattern made from squares. Only basic LOGO knowledge needed.
Can you use LOGO to create a systematic reproduction of a basic design? An introduction to variables in a familiar setting.
