Use to teach shape names, counting (eg 3, 6, 9 or 4, 8, 12), fractions, angles and algebra. Looking at the rhombus, trapezium and hexagon pattern below: What would pattern piece 12 be? What about piece 14? What about piece 15? What is the rule linking pattern number and piece for each of the shapes?)
Set of 8 shapes (15 of each shape) = 120 pieces @ $16 per set + p&h.
