In the Geometry Progression document, on p. 6 the illustration for K.G.4 has as the top difficult distractor for rectangles a shape that looks like a rectangle to me (and other people). Was it supposed to be not closed or have some other deformity or am I not seeing something obvious?
Thanks for mentioning this. It was also mentioned in February (I think somewhere on the forum). Anyway, the revised figure is now up on my blog: http://mathedck.wordpress.com/?attachment_id=431.
