Wiring a Plug to be Controlled by a Switch

How to Wire Half-Hot Plugs and Switched Outlets
Electrical Question: How can I have the top plug to be switched and bottom to be live?

• I have a switch in a bedroom with three outlets which does not seem to have a purpose.
• The top and bottom plugs on all three outlets are hot with the switch in on or off position.
• The top and bottom plugs all remained hot even after disconnecting the Red and Black wires from the switch.
• Additionally, the Red and Black wires at the switch tested hot after being removed from the switch.
• Ultimately, my goal is to have top plug to be switched and bottom to be live.

Any thoughts would help.
Thank-you.
