WOODFORD COUNTY, Ky. (FOX 56) – A Woodford County student’s clever thinking came in handy when it was time to prepare for a test.

His teacher, Conner Richardson, tweeted a photo of Braden holding a 3-by-5 foot notecard Thursday morning.

“Today, I learned a good lesson about clarity in teaching from @BLacefield’s son. If you tell students they can use a 3X5 notecard on an exam, be sure to specify that you mean inches and not feet,” read the tweet.

Richardson said it made for a good laugh.

In the end, Braden didn’t think he’d need the notes for the test and chose not to use it.

“Maybe someday he will use his powers for good,” Braden’s father Brian Lacefield said.
