Recently a teacher who was finding this session challenging suddenly asked: "Are you trying to get us to think differently?". Well, yes, but not me, Scottish educator Geoff Giles, the creator of the concept. A square is X. A quadrant with a radius the same length as a side of the square is Y. Using materials, you will dig into spatial challenges and connect with algebra such as the concept of a pronumeral, combining like terms, the distributive law and linear factorisation, mostly by asking: "Can I check this another way?". A master for the materials and links to investigation guides will be supplied.
