Have you tried nesting blocks with colors, letters and animals on them? It's a great way to learn names of things and letters while putting the smaller ones into the bigger ones or placing them on top of each other to build a big tower. Also, the Lego Duplo blocks are very big and my daughter loves taking them apart as much as putting them together. She got one big bucket on her 1st birthday and is still getting a lot of play out of them 15 months later.
Also, what about puzzles with big pieces... simple, small ones with animals on them? Eric Carle has good ones that go with his books. Melissa and Doug also make an entire series of large piece floor puzzles that are big and have different subjects.
My daughter also loves stickers and there are books that have stickers on everything from numbers/ABCs/clothing/characters/animals.
And... she might be ready for dress up soon. Try a small first purse or floppy hat or beaded necklace (not tight, very loose and supervise at all times when it's around her neck for obvious reasons).
Good luck!
