Connecting effects through mixer

[clt2sdf]

I have 4 keyboards that I run through a 8 channel mixer....2 in stereo and 2 L/mono. I've always connected straight keyboard to mixer but have recently bought some effects....a wah pedal, bassballs and line 6 POD. My question is....how to connect everything. This mixer is a PV8 (peavey). So from the keyboard...output of the keyboard to the line in on the mixer and then out to the monitors. How does a pedal fit in? Sorry for the confussion...??
thanks in advance

Keyboard --> Pedals --> Mixer --> Monitors

I've never used any pedals, but I think that's how it's supposed to be done.
