Generally the old style cement blocks are not used anymore. Steel chairs are used instead. Both are used more for rebar than for 8-10 gauge welded wire fabric. Each one makes it difficult to walk the wire without distorting it or tripping and the cement block draws water from the mix.
(They are 2" cement blocks with wire ties protruding from one end. Set a block then secure the wire with the ties. If used, wet thoroughly before the pour).
For welded wire fabric make a wire hook or purchase one. It's 1/4" steel rod, about 30" long, with a 90 degree hook at one end and a handle at the other. As the concrete is poured the wire is hooked and pulled up.
The other way to handle wire is two passes. Pour the base, lay the wire, then top (not very effective on large pours).
As necessary overlap the wire by at least one square then tie overlapping sections together by clipping a wire every 12-18" and bending it over the next sheet.
