Start by assigning oxidation numbers to all the atoms that take part in the reaction--it's actually a good idea to start with the unbalanced chemical equation
0
Mg
(
s
)
+
0
O
2
(
g
)
→
+
2
Mg
−
2
O
(
s
)
Now, notice that the oxidation state of oxygen goes from
0
on the reactants' side to
−
2
on the products' side, which means that oxygen is being reduced.
The reduction half-reaction will look like this
0
O
2
+
4
e

→
2
−
2
O
2
