When you need to cut a sheet of plywood, you can go through all the trouble and fuss of lifting the sheet and positioning it on 2x4's or sawhorses, and then risk life and limb as you reach and strectch do do the cuts, and the blade pinches...or you can try this favorite trick of mine.
Just throw the sheet on the grass, set your skill saw to just barely cut through the plywood thickness, and go ahead and cut. Nothing is required underneath, and you can crawl all over the sheet while you work. It works great, I've been doing it for 25 years as a professional signmaker. There's no need to lift the sheet, no helper required, and it's much faster and safer!
