## MATH GAMES FOR ADULT AND CHILDBEAT THE TENS TOPIC and LEVEL: Counting: Advanced; Addition/Subtraction: Intermediate, Advanced; Families: Intermediate, Advanced; Problem Solving: Intermediate, Advanced PLAY AFTER: SUMTHING ELSE PLAY WITH: SUMTHING ELSE EQUIPMENT: A deck of cards: 4 suits, ace through 10. TO WIN: Find more pairs totaling 10 than sets of 4 cards with no pairs totaling 10. TO END: All 10s are uncovered. TO PLAY: - Shuffle deck. Deal 4 cards face-up in a row.
- If a 10 is uncovered, remove it and use it as a counter.
- Fill vacant spaces with cards from deck.
- If a pair of cards totaling 10 is found, remove it and count it as one earned point.
- If no pair of cards totaling 10 is found in the set of 4 face-up cards, remove the set of 4, counting them as 1 lost point.
TO LOSE: Number of points earned is less than the number of points lost. This is a game of solitaire. The adult handles the cards and perhaps coaches a bit, the adult and child comment on the likelihood of success, but mostly the game is played silently. As with DONE, FOR 2, 3, OR 4, or SUMTHING ELSE, the number families are emphasized. In particular, this games highlight the tens family. In a first-grade setting, the families are often drilled. With these card games, the families are repeatedly reviewed but never drilled. This is not a beginner's game. Don't play it unless the child has facility with SUMTHING ELSE and with FOR 2, 3, OR 4. To play use four suits of ace through 10, the BEAT THE TENS deck. Shuffle. Deal four cards face-up in a row. Try to find two cards whose sum is 10. If such a pair is found, remove the pair from the row of cards placing it face-up to the side to be counted as one earned point. Above, the ace and a nine have been removed because their sum is ten. The vacant spaces are filled with cards from the undealt deck, in this case a 10 and a 7 of hearts. If at any time, a ten turns up, remove it from the row of cards and place it face-up to the side as a counter. The goal is to earn as many points as possible before all four 10s surface. When all four 10s surface, the game ends even if more cards are to be played. Fill each vacant space with a card from the undealt deck. If at any time, the four up-turned cards cannot be used to make a pair totalling ten, remove all four cards and place them face-down to the side to be counted as one lost point, as shown below. A set of losing cards may be crossed with a pair of winning cards to make a cross equalling zero points. If a group of three or four cards is found which totals ten, they may NOT be removed and counted as a winning point. In the figure below, the 7 of spades, ace of hearts, and 2 of clubs form such a group. Their sum is 10. The 10 of spade must be removed as a timer card. TO WIN THE GAME, THE NUMBER OF POINTS YOU EARN MUST EXCEED THE NUMBER OF POINTS YOU LOSE. If the number of points earned equals the number of points lost, you have tied; if it is less than the number of points lost, you have lost the game. Again, coaching is permitted. When a child asks, "Do you see any (pair totaling ten)," please respond. If you see a pair and the child does not, point to one of the cards in the pair and silently wait. Attempt to verbally interact only when requested to do so. |
