Is it possible to keep track of the names?

I'm making a 10x10 board generator just so i can get used to algorithms. I would like to know if it would be possible to keep track of the very first block spawned up to the last. In other words; the first spawned brick is named 1 and the last would be named 100.

My current script generates but...Doesn't seem to keep track properly

for z = 1,40,4 do
    for i = 1,40,4 do
        local p = Instance.new("Part", game.Workspace)
        p.Anchored = true
        p.Size = Vector3.new(4,1,4)
        p.Position = Vector3.new(i,0,z)
        p.Name = (z)
    end
end

Thanks for the help :)
