Talking about all the objects along the way with your kiddo while going on a walk.
When kiddos are just learning to talk, they've begun their journey into associating words with symbols. Keyboard-Smasher games are awesome for interactively streamlining word association with objects, animals, letters, numbers, shapes, colors, etc–which pop up on the screen when a button is pressed or mouse is clicked.
I went with bambam since it was relatively up-to-date, and easy to grab more images and drop them into the game's image folder it grabs them from as the child's vocabulary grew. I also set this up on a Raspberry Pi to avoid the danger of 'smashing' my work computer.
