Oohh my wee guy at nearly one LOVES plain wooden blocks, we spend ages stacking them up together and smashing them down.
Books definitely a go-er, can NEVER have enough books in my opinion.
He also loves toy phones. Wee matchbox cars are great cos they go "brrmmmm" everywhere with him hehe!
we've also go this stupid wee elmo head thing on wheels, which sits inside a wee bubble, and the top moves up and down when you move it and it makes dumb elmo noises. He loves it cos its got a string to drag it along and wheels and it makes noises

typical boy! Hehe.
He also loves things he has to 'put together'.... And he LOOOOVES daddys toolbelt and playing with the tools.
