Investigate the different shaped bracelets you could make from 18 different spherical beads. How do they compare if you use 24 beads?
How many rectangles can you find in this shape? Which ones are
differently sized and which are 'similar'?
Draw three straight lines to separate these shapes into four groups
- each group must contain one of each shape.
How many quadrilaterals are there in the diagram?
