Acre lots in a good school district are hard to find unless you have a big budget or are willing to have a loong commute.
If you don't mind me asking what is your budget? (I'm a native Houstonian, grew up on the NW side of town but now live S of Houston)
I found this map, little outdated but it gives you an idea of locations /distances:

Basically in-town you have spring branch ISD.
S of town you have Clear Creek, Pearland, and Friendswood ISDs.
W of town you have Fort Bend and Katy ISDs.
N of town is Cy-Fair, Klein, and Humble ISDs.
