Rukhsh from Jumeirah Primary School wrote to tell us:
With the yellow hexagon and the yellow circle you can have all the yellow shapes.I'd agree! How about the red triangles? What could have gone with them instead of the other triangles?
Arrange the shapes in a line so that you change either colour or shape in the next piece along. Can you find several ways to start with a blue triangle and end with a red circle?
