Kids get a number grid with the different place values and a page to create their secret number. First, they come up with a number and write it in the boxes (shown above). Then, they take turns asking each other questions.
Do you have 7 tens?
Is your number in the hundreds place greater than 2?
If they guess correctly, they got a "hit!" So, they circle the number on their grid. If their guess was incorrect, they make an x through the number on the grid. The first one to figure out their opponent's number wins!
