Readers Love Denises Playful Math Books

These games are great for using and practicing maths skills in a context in which there is some real motivation to do so. I love how they provide opportunities to explore a wide variety of approaches, including number bonds and logical thinking.

My children are always pleased, even excited, when I suggest one of these games. Sometimes they even ask to play them unprompted!

Miranda Jubb, online reader review

It revolutionized our homeschool this year.

Caitlin Fitzpatrick Curley, My-Little-Poppies.com

I have played several of these games with my son, and each one was met with delight on his part and the sharing of delightful conversation about numbers and thinking between us.

I love what Gaskins has to say about working with your children as opposed to simply assigning them work to do. This sums up the philosophy that I try to keep forefront in our home.

Highly, highly recommended.

Amy, Hope Is the Word blog

Wonderful games for elementary students. The author includes a link for printable game boards, ensuring that I don't spend more time making games than playing them. Variations for each game = SO many ways to explore numbers. You will love this book.

Sample Game: Nine Cards

Math Concepts: addition, number bonds for ten.

Players: two or more.

Equipment: one deck of math cards.

How to Play

The first player shuffles the deck and then turns up the top nine cards, placing them face up in a 3 3 array: three rows with three cards in each row. The player captures (removes and keeps) any tens and any pairs of cards that sum to ten, then passes the deck to the next player.

Each player in turn deals out enough cards to fill in the empty spots in the array, captures any tens and number bonds, and passes the deck on.

The game ends when the deck is gone or when there are not enough cards left to fill in the holes in the array. Whoever has collected the most cards wins the game.

[Picture below] Claim the ten and the pairs of cards that add up to ten. Do not take longer sums, like 5 + 2 + 3.

Variation

Concentration (Memory): Lay all the cards out face down on the table in a single layer with no overlaps. On your turn, flip two cards up. If you find a ten or a number bond, take it. If not, leave the cards showing long enough that all the players can see what they are. Then turn them face down before the next players turn.

History

Tens Concentration has always been one of my favorite math games. The face-up Nine Cards version comes from Constance Kamiis Young Children Continue to Reinvent Arithmetic.

Sample Game: Tiguous

Math Concepts: addition, subtraction, multistep calculation.

Players: two or more.

Equipment: game board, three six-sided dice, pencil or marker(s), scratch paper for keeping score.

[Picture below] Which square would you mark?

Set-Up

You can print the Tiguous game board from the Number Game Printables Pack, download the Contig, Jr. game from Terry Kawass MathWire website, or have your children make their own game board.

If students make their own board, they can arrange the numbers however they like:

Draw a 6 6 grid of squares, each big enough for a two-digit number.

The first player writes the number one in any square. The next chooses a square for the number two. Players take turns writing the numbers 118 anywhere they wish, one number per square.

After eighteen, the next player goes back to one, and the turns continue until the board is full.

How to Play

On your turn, roll all three dice. If any die falls off the table or lands at a slant, all three dice must be rolled again. Do not touch the dice with your hands after they are rolled, though you may use a pencil or marker to scoot them next to each other.

Add or subtract these three numbers in a two-step equation that equals the number in any unmarked square on the game board. Think of as many possible combinations as you can, in order to choose the highest-scoring square. Mark your answer on the game board with a large X. At the same time, say out loud how you calculated the number.

You score 1 point for the square you marked, plus 1 point for each already-marked square that is touching (contiguous to) any side or corner of your numbers square. The maximum score for any turn is 9 points. If all the numbers you can make have already been marked, you score a zerobut if anyone else can find a valid calculation using your dice, that player may challenge you, mark the square, and steal those points.

If another player thinks you made an arithmetic mistake, that person may challenge your answer before the next player rolls the dice. If your answer was wrong, the challenger takes the points you would have won, and you score zero. If your calculation is correct, you get one bonus point for having withstood the challenge.

Play until each player has had ten turns, or five turns each for three or more players. Whoever has the highest total score wins the game.

Variations

The most common variation I have seen is not to score a point for the marked square. Just score 1 point for each contiguous square that was previously marked, which makes the maximum possible score per turn only 8 points. I strongly prefer the scoring system above, which awards at least 1 point for any valid calculation.

Tiguous-Tac-Toe: Two players mark numbers with X and O, and the first player to get three squares in a row wins. Rows may be vertical, horizontal, or diagonal. For a longer game, try to get four or five in a row.

Multiplayer Extended Game: Keep playing until almost all the numbers are marked. Any player who gets a zero three turns in a row drops out of the game. When the last player gets a third strike, the game is over. There is no bonus for the last player, other than the extra turn(s).

Tournament Rules: Two players per game board. Set a timer, giving each player only thirty seconds for each turn. Think fast! If you do not mark a square within the thirty seconds, your score is zero for that turn. Scores of zero may not be challenged in tournament play, but opponents may challenge arithmetic errors. After each player has ten turns, add up the players scores for that round. Then trade partners, get a new game board, and play another round. After three rounds, award 1st, 2nd, and 3rd place ribbons to the top scorers in each age group/grade level.
