What Is Math Game Monday?

Learn a new math game every week, for free

There’s a new Math Game Monday this week.

Have your kids tried it yet?

This week’s game is one of my favorites for upper-elementary and middle school students, offering plenty of practice doing estimation and mental math with fractions. Or you might prefer last week’s game, featuring a classic two-player logic puzzle that develops strategic reasoning.

Or, if you’re reading this post later and missed those, there’s another great new game this week for you to play.

Playing to Learn

quotation from Dan Finkel

“Play and rigor support each other.

    “When students are invited to play with math, they learn more deeply, more robustly, and remember more consistently.

      “Play is promoted as something that can engage kids and give them a more positive attitude about school, but it’s easy to assume that it’s not useful for learning, when in reality the opposite is true:

        “The student who is playing tends to be the student who is learning most deeply.”

        Playful Math for the Summer

        playful dog at the beach

        I continue to dig myself out of the avalanche of tasks that built up during the years that I spent mostly down south with my mom as she was weakening.

        But here are two tidbits of mathy fun that came across my desk recently, which I think you’ll enjoy…

        Numberhive Place Value

        I think I’ve mentioned before how much I love the Numberhive game. They recently posted a series of print-and-play freebies for their new place value variation.

        DiceCulus Core Game — Mini PnP

        This cool-looking game is in prelaunch on the crowdfunding site Gamefound, but the creator has posted a free Mini Print & Play version you can download now, suitable for prealgebra and up. (The full game will have multiple variations, including a preschool level.)

        Math Journaling and Games

        Finally, the Math Journaling Adventures books and kids’ gear are now live in my store, and all my math game books are still on sale through the month of June.

        Have fun playing math with your kids!

        Podcast: Using Math Journals and Games

        I have a new podcast interview, and I think you’ll enjoy it!

        Here’s an excerpt…

        Writing to Learn

        Just as a nature journal records our children’s explorations and discoveries in nature, so a math journal tracks our children’s explorations in the world of mathematics.

          In a math journal, children record their experiences with numbers, shapes, and patterns through drawing or writing. Journaling teaches them to see with mathematical eyes — not just to remember what we adults tell them, but to create their own math.

            The process of writing forces children to pin down their thoughts, to transform nebulous concepts into firm ideas, to struggle with vagueness and build understanding.

              As William Zinsser says in his book Writing to Learn: “Writing is how we think our way into a subject and make it our own. Writing enables us to find out what we know, and what we don’t know.”

                Through journaling, children develop a richer mathematical mindset. They begin to see connections and grow confident in their ability to think through new problems.

                We had a great discussion! Listen to the whole thing:

                Playful Math 179: Our Sweet Sixteen Carnival

                Welcome to the sweet-16 birthday edition of the Playful Math Carnival. Originally called Math Teachers at Play, our first carnival was published in February 2009.

                Each Playful Math Carnival offers a smorgasbord of delectable tidbits of mathy fun. It’s like a free online magazine devoted to learning, teaching, and playing around with math from preschool to high school.

                There’s so much playful math to enjoy!

                By tradition, we start the carnival with a math activity in honor of our 179th edition. But if you’d rather jump straight to our featured blog posts, click here to see the Table of Contents.

                NOTE: Our wonderful volunteer hosts have kept the Playful Math Carnival going when so many other blog carnivals died off. If you’d like to sign up to host the carnival for a month, email Denise for information.

                Try These Prime Puzzles

                Did you know there are 179 even-numbered days this year?

                • How many even-numbered days will there be in a leap year?
                • But there are 365 days in a standard year and 366 in a leap year. Shouldn’t there be half that many even-numbered days?

                179 is a prime number, and it’s also a knockout prime. You can knock out any of the digits, and what’s left is still prime: 17, 19, or 79.

                • Can you find another knockout prime number?

                179 is a twin prime. That means that one of its odd-numbered neighbors is also prime.

                • Is the other twin 177 or 181? Can you tell without looking it up?
                • Why are twin primes limited to the odd numbers? That doesn’t seem fair!

                179 is also an emirp. That’s a special kind of prime that forms a different prime number when you write it backwards: 971 is also prime.

                • How many emirps can you find?

                “A palindrome is a word that when written in reverse results in the same word. for example, ‘racecar’ reversed is still ‘racecar’. Related to palindromes are semordnilaps. These are words that when written in reverse result in a distinct valid word. For example, ‘stressed’ written in reverse is ‘desserts’. Not all words are palindromes or semordnilaps.

                  “While certainly not all numbers are palindromes, all non-palindromic numbers when written in reverse will form semordnilaps.

                    “Narrowing to primes brings back the same trichotomy as with words: some numbers are emirps, some numbers are palindromic primes, but some are neither.”

                    Puzzle: Henry Dudeney’s Pebble Game

                    photo of girl playing with pebbles on the beach

                    English mathematician and puzzle-meister Henry Ernest Dudeney once wrote:

                    “It may be said generally that a game is a contest of skill for two or more persons, into which we enter either for amusement or to win a prize. A puzzle is something to be done or solved by the individual.

                      “The example that I give here is apparently a game, but, as in every case one player may win if he only play correctly, it is in reality a puzzle. The interest, therefore, lies in attempting to discover the leading method of play.”

                      Below is the puzzle game as Dudeney explained it.

                      Play it for fun at first, then see if you can solve the puzzle.
