Installing sidewalk expansion joints as you go?

I'm new to this side of the site, so go easy on me....I've been roped into pouring a 30ft concrete sidewalk, but the guy I'm helping is hell-bent on using those fiber-based expansion joints every 5ft. Personally I'd just come back and saw-cut it, but to each their own.

My question is, how on earth would you install those as you go, seeing as how this is going to be a continuous pour? Being as that they're flexible, I don't see any way of keeping them perfectly straight so that you have nice,clean,even lines when you're done.

Any help or input is appreciated.

Are you pouring off a truck or mixing your own on site?

Use your screed as a straight edge, push joints into the crete and flatten smooth with your mag.

We're pouring off the truck.

So I get pushing the joints into the wet crete, but I guess it's just a matter of eyeballing it to keep it straight? Mark a line on both form boards and go from there?

Stake it in, back it up with a 2x4 and pull it out as you pour, thats how we do it with the paper joints. But you don't need it every 5', just drop lines in it
