How to play
:
Think of a
three digit number (example : 615)
Ask a student to guess a three digit number. The student perhaps says 357
Write this number in the table below.
You then write 1 in
the Correct
digit, wrong place because the number submitted by
the student has one
correct digit that is in your number
(615)
but it is in the wrong place.
Using this visible information, ask another student to guess another
three digit number. The student guesses perhaps 485.
Write this
number in the table below.
You then
write 1 in
the Correct
digit, correct place because the number submitted by
the student has one correct digit that is in your number (615)
and it is in the correct place.
Using this visible information,
ask another student to guess a three digit number. The student guesses
perhaps 265.
Write this
number in the table below.
You then
write 1 in
the Correct
digit, correct place column and 1
in the Correct
digit, wrong place column because the number
submitted by the student has a correct digit (5) that is in your number (615)
and it is in the correct place and also the student has
guessed a second digit (6)
which is in your number but is not in the correct place.
Practice with your students. Have fun!
