Group Activity Cards
groups of 4.
Materials: Index cards
group member takes an index card and turns it so that the longer sides are at
the top and bottom. Each group member then draws a vertical line down the middle
of the card and writes a two-digit number with the digit in tens place to the
left of the line and the digit in ones place to the right of the line. Finally,
each group member cuts his or her card along the line and cuts one of the corners
off the cards with digits in the tens place.
as a group, solve the following problem: How many different two-digit numbers
can you form using the cards you made? (Hint: Use your cards to make an organized
list of all the possibilities.)
