Edgewood Math: Math Games 1-3

Turn Over 10

Materials:  Deck of Number Cards 0-10
(or playing cards with face cards removed)    

         
Players:       2

Objective:  Find as many combinations of 2 cards that total 10.

How to Play:
1.  Place all cards face down in a rectangular arrangement (an array). 
2.  Players take turns turning over 2 cards.  If the two cards added together have a sum of 10, the player keeps the pair.  If not, the player turns them back over.

3.  The game ends when all possible combinations have been taken.

Variations:

1.  Turn over 6 - use only 0-6 cards to make sums of 6.

2.  Use more than 2 cards to get to 10.  - Player continues to turn over cards until they get to 10, or goes over.  If they go over 10 and do not reach a sum of exactly 10, they turn the cards back over.

Addition Top It

Materials:    Number card 0 - 2 (2 sets)

Players:       2 or more

How to Play:
Players combine and shuffle their cards and place them in a pile, facedown.  Each player takes 2 cards from the top of the pile and says the sums of numbers.  The player with the greater sum takes all of the cards then in play.  The player with the most cards is the winner.  Ties are broken by drawing again - winner takes all.

High Roller

Materials:  2 dice

Players:  2 or more

How to Play:
One player rolls 2 dice.  The player keeps the die with the larger number (the High Roller) and throws the other die again.  The player then counts on from the number rolled on the first die to get the sum of the 2 dice.

Beat the Calculator

Materials:  Number cards 0 - 10 (4 of each)

Players:     3 (a Caller, a Calculator, and a Brain)

How to Play:
Shuffle the cards and place the deck facedown.  The Caller turns over the top 2 cards.  The Calculator finds the sum of the numbers on the cards by using a calculator.  The Brain solves the problem without a calculator.  The Caller determines who got the correct answer first.  Players trade roles.

Do Anytime Activities

Telling Time and Using Money:
♦ Practice telling time by using a variety of clocks - billboard clocks, wristwatches, clocks with hands, and digital clocks - in a variety of situations.
♦ Set alarm clocks and timers on objects such as ovens, microwave ovens, and DVD players.
♦ Record the time spent doing various activities.
♦ Use real money in a variety of situations; allowance, savings, purchases (including getting change back), and using vending machines.

Weather Watch:
♦ Invite your child to share your interest in weather predictions and temperature reports from the radio, the television, and local and national newspapers.
♦ Observe temperatures shown on business signs, aquarium thermometers, and so on.
♦ Read and set temperatures on heating and cooling thermostats and oven dials.

Compare/Double Compare Instructions

Materials:  Deck of Number Cards

Players:      2

Object:       Decide which of two sums is greater

How to Play:
1.  Mix the cards and deal them evenly to each player.  Place your stack of cards face down in front of you.
2.  At the same time, both of you turn over the top card in your stack.  Compare your card to your partners to determine which number is greater.  If your card is more than the other player’s, say “Me!”  If the two cards are the same, turn over the next card and compare these numbers.
3.  Keep turning over a card.  Say “Me!” each time your card number is more.
4.  The game is over when you have both turned over all the cards in your stack.

Variations:

1.  Remove the 7-10 cards from the deck, and play with just the 0 - 6 cards.

2.  Play Double Compare.  Players turn over two cards on a turn.  The player whose total sum is more says “Me!”  If the tow totals are the same, turn over the next two cards and compare these sums

3.  Add the four wild cards to the deck.  A wild card may be used as any number.  Challenge students to use it for the lowest number that will allow them to win

4.  Play Triple Compare.  Players turn over three cards on a turn.  The player with the larger total says “Me!”

Tens Go Fish

Materials:  Deck of Primary Number Cards (without Wild Cards)
                 Sheet of Paper

Players:       2

How to Play:
1.  Each player is dealt 5 cards from the Primary Number Card deck.
2.  Each player looks for pairs from his or her cards that make 10.  Players put down the pairs of cards that make 10, and they draw new cards to replace them from the Primary Number Card deck.
3.  Players take turns asking each other for a card that will make 10 with a card in their own hands. 
4.  If a player gets the card, he or she puts the pair down and picks a new card from the deck.

5.  If a player does not get the card, the player must “Go fish” and pick a new card from the deck. 

6.  If the new card from the deck makes 10 with a card in the player’s hand, he or she puts the pair of cards down and takes another card.

7.  If a player runs out of cards, the player picks two new cards.

8.  A player’s turn is over when no more pairs can be made that make 10.

Penny Grab

Materials:  20 or more pennies; paper and pencil

Players:      2 or more

How to Play:
Each player grabs a handful of pennies, counts them, and records the amount with cents and dollars-and-cents notation.  For example, a player would record 14 pennies as both 13¢ and $0.13.  Partners compare their amounts and then figure out and record how many in all (the sum).  Players repeat the grabs several times.

Variation:  Use nickels or dimes.
