I'd draw a 4 x4 grid on the board The top row first square was blank write 2nd person, 3rd place, 4th thing
down the left column fill in the the 2nd 3rd 4th square with a letter.
After they played a few times I'd call on students for the letters
Then call on students to give answers.
say V the answers might be veterinarian or Vicki, Virginia, valentine
They can say the letter and and category...gets harder as the choices are used up. Some letters are easier to answer.
Hope that made sense...

Enjoy first grade. I taught it for many many years. They grow so much.
