Math War for Simultaneous Equations

Posted on by Denise Gaskins

Just updated my blog post Math Game: War with Special Decks to add a game I missed the first time around:

Math War is the most worksheety of all the math games I play with kids. But you can add a level of choice by playing the Trumps version.

Math War Trumps: Instead of playing for the highest sum, as in Julie’s original game, have each player draw 3 cards. The player whose turn it is first names “X” or “Y” as trump, then all players lay down a card. Highest trump value wins the skirmish.

Variation: Let the player naming trump also decide whether the highest or lowest value will win.

Playful Math Carnival #154: The Math Journaling Edition

Posted on by Denise Gaskins

Welcome to the 154th edition of the Playful Math Education Blog Carnival — 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.

Bookmark this post, so you can take your time browsing.

There’s so much playful math to enjoy!

By tradition, we start the carnival with a puzzle/activity in honor of our 154th edition. But if you’d rather jump straight to our featured blog posts, click here to see the Table of Contents.

Try This Puzzle/Activity

Since 154 is a nonagonal number, I think you might enjoy visiting some of my old “Adventures of Alexandria Jones” posts about figurate numbers:

And then try this math journaling prompt: Build or draw your own nonagonal numbers — numbers built from 9-sided polygons.

How many nonagonal numbers can you find? What do you notice? Does it make you wonder?

Playful Math #152: Auld Lang Syne Edition

Welcome to the 152nd edition of the Playful Math Education Blog Carnival — 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.

We didn’t have a volunteer host for January, so I’m squeezing this in between other commitments. This is my third no-host-emergency carnival in the last year, which is NOT sustainable. If you’d like to help keep the Playful Math Carnival alive, we desperately need hosts for 2022!

By tradition, we start the carnival with a puzzle or activity in honor of our 152nd edition. But if you’d rather jump straight to our featured blog posts, click here to see the Table of Contents.

Math Journaling with Prime Numbers

Cool facts about 152: The eighth prime number is 19, and 8 × 19 = 152. When you square 152, you get a number that contains all the digits from 0–4. You can make 152 as the sum of eight consecutive even numbers, or as the sum of four consecutive prime numbers.

But 152 has two real claims to fame:

  • It’s the smallest number that is the sum of the cubes of two distinct odd primes.
  • And it’s the largest known even number you can write as the sum of two primes in exactly four ways.

So here’s your math investigation prompt:

  • Play around with prime numbers. Explore their powers, their sums, and anything else about them you like.
  • What do you notice? What do you wonder?
  • What’s the most interesting number relationship you can find?

Michael and Nash have been creating and posting new math games with astonishing regularity throughout the pandemic. Their YouTube channel is a great resource for parents who want to play math with elementary-age children.

Today’s entry: Closest to Ten, a quick game for addition and subtraction fluency with a tiny bit of multiplication potential.

And here’s one of my favorites for older players: Factor Triangles, a card game for 2-digit multiplication.

How to Build Math Literacy

Posted on by Denise Gaskins

Here’s the full quote:

We all know reading a book each day to our child develops their love of literacy… well, playing games is the equivalent in maths.

Through playing card games and board games (just short and sweet ones) children develop problem solving, counting and so many other skills.

Imagine if every time you play a game you say, “Let’s do some maths.” What a positive association your child will develop with maths!
