Card Smarts

What you'll need
Pack of cards

What to do
1. How many numbers can we make?
Give each player a piece of
paper and a pencil.
Using the cards from 1 (ace)-9, deal 4 cards
out with the numbers showing.
Using all four cards and a choice
of any combination of addition, subtraction, multiplication, and division, have each player see how many different answers a person can get in 5 minutes.
Players get one point for each
For example, suppose the cards drawn are 4, 8, 9, and 2.

What numbers can be made?
4 + 9 + 8 + 2 = 23
4 + 9 - (8 + 2) = 3
(8 - 4) x (9 - 2) = 28
(9 - 8) x (4 - 2) = 2

2. Make the most of it.
This game is played with cards from 1
(ace) to 9.
Each player alternates drawing one card at a time,
trying to create the largest 5-digit number possible.
As the
cards are drawn, each player puts the cards down in their "place" (ten thousands, thousands, hundreds, tens, ones) with the numbers showing.
One round goes until each player has 6 cards.
At that
point, each player chooses one card to throw out to make the largest 5-digit number possible.

3. Fraction Fun.
This game is played with cards 1 (ace)-10, and
2 players.
Each player receives one-half of the cards.
turn over 2 cards each at the same time.
Each player tries to
make the largest fraction by putting the 2 cards together.
players compare their fractions to see whose is larger.
example, if you are given a 3 and a 5, the fraction 3/5 would be made; if the other person is given a 2 and an 8,
the fraction is
Which is larger? The larger fraction takes all cards and
play continues until one player has all the cards.
