Maths Problem Pictures are about bringing mathematics to life with photographs. Striking photographs are combined with original questions and problems to challenge students at all levels. Although they are aimed at more able students, some of them will be accessible by primary maths students.
The images are not free - you'll need to buy a CD Rom for £22 but they really do bring maths to the real world. Some example images are shown below and the link for all 25 of the examples is here.
