If you want to have some good fun with your kids you should download some Coloring Pages from a good website. As he colors I tell him the names of the colors and he is already picking them up easily, especially his favourites Green and Brown. Every time he begins to use a word I have taught him I really get a unique buzz that you have to be a dad to understand. I really appreciate all the little contributions I can make. I also tell him the names of whatever he is currently coloring, like an arm, a leg, a tree, a bus and so on. All learning really comes from repetition so by saying these names over and over he will pick them up fast.
You can also get dino coloring books and activities to buy - these make great birthday or Christmas gifts or treats on a rainy day. You can get a dinosaur T-shirt with washable markers than you can create your own design with over and over. Prehistoric posters colored by your child are also good fun. There's even a great dinosaur puzzle to color - our kids love puzzles and coloring so this is a great idea.
