A simple sheet for your students to play Place Value Battleship with! Each student has their own sheet, chooses their number, and writes it down. They must then ask yes or no questions ("Is a 7 in the hundreds place? Is an even number in the tens place?") and cross out numbers accordingly. The first player to be able to write all three forms of their opponent's number is the winner!
