Blocks, marble run, musical instrument, binoculars, magnifying glass. Aldi and Lidl usually do lovely wooden marble runs for around a tenner in the run up to Christmas, and Aldi do a fabulous bargain version of Kapla blocks which are played with happily by people of all ages in our house. Jigsaws. Board games - Tummy Ache (cheap) and Max the Cat (more expensive) are popular here. Art stuff.
