"Mom, come look at this! I spelled FART ZOMBIE!!!!!" (giggles galore)
A little bit of phonics work later and we had the correct spelling of "fart zombie". Admit it, you're having a hard time not giggling while looking at this little crackin' up face.
I'm learning that with boys, any way you can practice phonics skills is a good way. If has to be funny words like "fart" so be it!
