Strip off the tips of a piece of wire using a wire stripper, measuring about half an inch from each tip to strip off. Solder one end of the wire to a ring terminal using solder and a soldering iron. Make a joint connection with the other end of the wire to a 10-kilo ohm resistor and pin 3 of your LM358 Op-Amp module, which is designed to use one power supply over a wide range of voltages.
Prepare a second piece of wire by stripping it the same way you did the first and make another joint connection with one of its ends to the terminal of the 10 kilo ohm that's not yet soldered, and one terminal of the 1 kilo ohm resistor. Prepare a 6V power supply, either a battery or a DC power source such as a motor, and connect the free end of the second wire to its negative terminal.
Solder the second terminal of the 1 kilo ohm resistor to one terminal of the10 kilo ohm. Make a clean soldered joint from the two terminals for smooth transmission of current through it.
Prepare another wire and solder one of its ends to a second ring terminal, then solder its other end to a joint connection of the free terminal of the 10 Kilo ohm resistor and pin 1 on the operational amplifier.
Solder one end of another wire to pin 4 of the operational amp and the other end to the negative terminal of the power supply. Solder the end of yet another wire to the positive terminal of the power supply and the other end to pin 8 on the op-amp
