  4. Math Game Monday: Bowling

    This game builds calculations skills and helps develop fluency.

    Many parents remember struggling to learn math. We hope to provide a better experience for our children. And one of the best ways for children to enjoy learning is through hands-on play.

    So what are you waiting for? Let’s play some math!

    Bowling

    Math Concepts: addition, subtraction, multistep calculation, column addition (for final score).

    Players: any number.

    Equipment: one deck of math cards, game board, ten tokens for covering numbers, pencil or pen, and (optional) scratch paper for adding up the scores.

    Set-Up

    You can print the bowling game board and score sheet from the Number Game Printables Pack, or draw your own game board and use the printable score sheets from the Apollo’s Templates website.

    Bowling game board and score sheet.

    The 23-page printable (pdf) Number Game Printables Pack file includes hundred charts, graph paper, and game boards from the first two Math You Can Play books.

    How to Play

    Place the deck face down where all players can reach. When it’s your turn, roll your bowling ball by flipping up three cards. On your game board, cover the pins you knock down:

    • The numbers on your cards.
    • Any numbers you can make by adding or subtracting two cards.
    • Any numbers you can make by adding and subtracting with all three of the cards. Each card may be used only once in each calculation.

    For example, if you roll a two, four, and ace, you can cover those numbers and also:

    • 3 = 4 − 1
    • 7 = 1 + 2 + 4
    • What else can you find?

    If you cover all the numbers, you rolled a strike, and that’s the end of your turn. If you don’t cover all the numbers, discard those cards and turn up three more for your next ball. Can you cover the remaining numbers now? If so, that’s a spare.

    Your score for each turn is how many numbers you cover, with special rules for strikes and spares as explained below.

    After you roll two balls, the next player takes a turn. Keep going until each player has ten turns. If the draw pile runs out of cards, reshuffle the discards to replenish it.

    How to Use the Score Sheet

    The rules for keeping score in bowling seem confusing until you’ve played a few games. Each larger square box on the score sheet is called a frame and represents your score for one turn. The two (or three) smaller square boxes are for keeping track of each time you roll your ball.

    One complete game of bowling consists of ten turns, with a maximum score of 300 points. You might think that with ten numbers to cover in each turn, the most you could score would be 100 points, but strikes and spares get bonuses.

    For each turn, write down how many numbers you covered with your first ball in the first small box, or if you got a strike, mark an X there. If you threw a second ball, mark down how many more numbers you covered in the second small box, or if you got a spare, write a slash (/). If you did not get a strike or spare, add the numbers you wrote down and put that total score at the bottom of the frame.

    A spare earns one bonus ball, and a strike earns two, which means you can’t finish scoring your frame yet. On your next turn, the balls you throw will count not only for their own frame but also as bonus points on your strike or spare. After you’ve thrown your next ball (or two balls, for a strike), add ten for the strike or spare plus the value of the bonus(es) and write in that total at the bottom of the unfinished frame.

    Notice that the bonus balls get counted twice, once as part of the strike or spare and once for their own frame. And if you throw three strikes in a row, the third one will be counted three times:

    • As the second bonus throw in the first strike frame.
    • As the first bonus throw on the second strike.
    • And finally as part of its own frame, along with its own bonus balls.

    When you get to the last frame, you will see three small boxes. That’s because any players lucky enough to throw a strike or a spare still get their bonus balls. If you don’t get a strike or spare, ignore that third little box.

    Finally, add up all the points from all ten frames to make your total score for the game.

  6. Math Game Monday: Greedy Pig

    This game tests each player’s risk tolerance as they roll dice to rack up points.

    Many parents remember struggling to learn math. We hope to provide a better experience for our children. And one of the best ways for children to enjoy learning is through hands-on play.

    So what are you waiting for? Let’s play some math!

    This game tests each player’s risk tolerance as they roll dice to rack up points.

    Greedy Pig

    Math Concepts: addition, probability of dice rolls, strategic thinking.

    Players: two or more.

    Equipment: two 6-sided dice, pen and paper for keeping score.

    How to Play

    Players agree on a target score, such as 100. The first player to reach or pass the target wins the game.

    Roll two dice as many times as you want, adding the numbers to your score. Stop when you wish, and pass the dice to the next player.

    Beware: If you roll a 1 before you stop, you lose all the points you added during that turn. If you roll double-1, your score resets to zero.

    Optional House Rule: If you roll doubles other than double-1, you have to roll again. You can’t end your turn on doubles.

    Variation

    Use the game as a journaling prompt. Here are some sample questions:

    • What is your strategy for winning?
    • Do you think this is a fair game, or does one player have an advantage?
    • How would you count score, so you could compare your performance from one game to the next?
    • How would you modify the game rules? Is your version easier or harder than the original game?
    • Do you prefer logical strategy games or games of chance? Or do the best games have a bit of both? Explain.

    History

    Pig is a folk-game cousin to Farkle and was first described in print by American magician and author John Scarne in his 1945 book Scarne on Dice.

  7. CW: NSFW: CyberSix [Comic] Spoilers, Violence, Drug Use

    Yeah, the CyberSix Comic is definitely not for Children.

    2 Issues in and we already have all the nasty stuff...

    Still, Do makes a sadly pungent point!

  8. On this day in 1984, I woke up hung over for the last time. I made a pledge I'd made before, but somehow this time it stuck. 42 years sober, 15,342 days without drinking or drugs. If you're struggling, this is to tell you it can be done.

    Here's what I wrote about it a couple of years ago:

    „Es waren drei Weise in Riesa,
    die zogen zum Studium nach Piesa,
    zwei machten ihr Glück,
    zwei kehrten zurück
    und lebten noch lange in Riesa.“

    Ist halt einer da geblieben. Ob nun mit oder ohne Glück.

    So lustig wie der #Witz mit der #Prozentrechnung neulich.
