His displacement is 8 blocks east.

Explanation:
When he walks to school, he walks 8 blocks east.
-------->
Then he returns home for lunch. It is the same distance. 8 blocks west.
<--------
The two distances cancel each other out.
Then he returns back to school. Same distance.
-------->
So his displacement is 8 blocks east.
