getting random child from model gives error?

When I try to get a random tool aka child i get an error Players.Danglt.Backpack.Remote.Tool:14: attempt to index field 'random' (a function value)

local crate2 = storage.Crate:Clone()
	for i,v in pairs(storage.rewards:GetChildren()) do
		local reword = v[math.random[1]]:Clone()
		reword.Parent = crate2.Reward
	crate2.Parent = workspace
	crate2.Configurations.Owner.Value = plr.Name
	for i = 1,1 do -- Replace 100 with an increment of times
crate2.Base:SetPrimaryPartCFrame(char.Torso.CFrame + Vector3.new(10,10,0))
end

[] is for index,

() is for function,

so it should be, math.random(1)
