How would i make a player teleport to a checkpoint when they die?

So, when the player dies, I want them to go back to the checkpoint they touched. I used a code and i don't know what the problem is and I am a bit confused on how to get this working. Any ideas on how? Here is my script I Wrote:

local checkFolder = game.Workspace.checkpoints

game.Players.PlayerAdded:Connect(function(plr) --// just defining the folder leaderstats
	local leaderstats = Instance.new("Folder")
	leaderstats.Name = "leaderstats"
	leaderstats.Parent = plr
	
	local checkpoints = Instance.new("IntValue") --// making a value in a folder called checkpoints
	checkpoints.Name = "Stages"
	checkpoints.Parent = leaderstats
	
	for i,v in pairs(checkFolder:GetChildren()) do
		if v:IsA("BasePart") then
			v.Touched:Connect(function(plr)
				local humanoid = plr.Parent:FindFirstChild("Humanoid")
				if i == 1 then
					checkpoints.Value = 1
					humanoid.Died:Connect(function()
						plr:WaitForChild("HumanoidRootPart").CFrame = CFrame.new(v.Position + Vector3.new(0,2,0)) --// this is where i get confused as it doesn't work. Any ideas?
					end)
				end
			end)
		end
	end
end)

I tried using CFrame and made it the position of the checkpoint plus 2 on the "y" axis. The For i,v in pairs part is finding all children in the folder checkFolder. Please help me
