Unity 5 missing Standard Assets

I have Unity 5 and when I make a new project, there are no assets that are usually there (Character Controller, Terrain, etc.). How do I fix that?

Select Window from the top menu, and open the Asset Store. On the right hand side of the page there is a list of categories. Select the Unity Essentials category. This category contains a number of asset packages published by Unity Technologies. Included in this pack is the Standard Assets package.
