Playful Math Carnival 144: Anniversary Edition

Posted on by Denise Gaskins

Welcome to the 144th 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 would start the carnival with a puzzle/activity in honor of our 144th edition. But this time, I want to take a peek back at the history of our carnival.

But if you’d rather jump straight to our featured blog posts, click here to see the Table of Contents.

Math Journals and Creative Reasoning

Posted on by Denise Gaskins

Learning math requires more than mastering number facts and memorizing rules. At its heart, math is a way of thinking.

So more than anything else, we need to teach our kids to think mathematically. To make sense of math concepts and persevere in figuring things out. To notice the numbers, shapes, and patterns all around. To wonder about big ideas.

Journaling is a great way to help children learn to see with mathematical eyes. Not just to remember what we tell them, but to create their own math.

Get started with creative math journaling today. Visit the Make 100 Math Rebels Kickstarter page to download the free “How To Be a Math Rebel” sampler pictured above, which contains one of my all-time favorite math prompts.

It doesn’t matter whether your students are homeschooled or in a classroom, distance learning or in person. Everyone can enjoy the experience of playing around with math.

A New Resource for Playful Math

Posted on by Denise Gaskins

Are you looking for new ways to explore math with your kids?

Would you like an easy, no-prep resource for creative problem-solving, number play, math art, word problems, mini-essays, brainteasers, patterns, research projects, and much more?

Check out the Make 100 Math Rebels Kickstarter project, which just might transform your child’s experience of math.

What Is a Math Rebel?

Math rebels believe in Truth. We refuse to accept something just because the teacher or textbook says it. We want to see the connections between math concepts and to understand why things work.

Math rebels care about Justice. We resist society’s push for speed and conformity. We reject the cultural narrative that math has only One Right Answer.

Math rebels celebrate Creative Reasoning. We delight in finding new ways to look at math topics. We want to think deeply about ideas, and we are confident in our ability to figure things out.

Launch your family’s math rebellion today with my free printable PDF booklet, “How To Be a Math Rebel,” available only on the Make 100 Math Rebels Kickstarter page.

Here’s the link again:

If you like what you see, I’d love to have your support. The more people we can get backing the project in the early days, the more likely Kickstarter will promote it to new readers.

What Are Mixed Numbers?

Posted on by Denise Gaskins

I just discovered a fascinating fact: In some places in the world, mixed numbers apparently don’t exist.

So that made me curious about my blog readers:

  • Did you learn about mixed numbers in school?
  • Do you ever use mixed numbers in daily life?
  • Are your children learning to work with them?

And if you DO know mixed numbers, can you simplify this mess:

[If you enjoy dry math humor, the answer is worth the work.]

Printable Activity Guides

Posted on by Denise Gaskins

Since my publishing house opened its online store last month, I’ve been busy stocking the shelves with printable math activities for all ages.

It’s a fun collection of low- or no-prep ideas for playing math with your kids.

And it’s still growing. I’m pouring through old notes of my favorite projects from years of playing math with the kids in our math clubs and homeschool co-op enrichment classes, looking for ideas.

Which One Will You Try?

We’ve made the first two Geometric Coloring Designs books permanently free.

[The Let’s Play Math Sampler is also permafree, though it’s an ebook, so it’s on a different virtual shelf. You can find it under the “Free Books” section.]

For the rest, we’ve kept our prices as low as possible to fit struggling family budgets — less than a cup of coffee at my favorite cafe, back when we could still go out for a sweet, creamy cuppa.

Just go to our online store and click the “Printable Activity Guides” button to check out all the mathy fun.

Here are all the books we’ve posted so far.

Math Art:

Games and Puzzles:

Math Facts and Number Play:

Someday, I hope to combine these books into a creative math “uncurriculum” for homeschoolers. Stay tuned to this blog for more news about that. Eventually…

Make Sense of Math

Posted on by Denise Gaskins

So, I decided to rewrite the Standards for Mathematical Practice into student-friendly language.

Here’s the final installment…

Math Tip #8: Make Sense of Math.

  • Use the patterns you discover to help you solve problems.
  • Don’t get lost in the details of a problem. Look for general truths.
  • Apply common sense to math situations.
  • Think about how different things are similar.
  • Think about how similar things are different.
  • Remember that your mind is your most important math tool.
  • Pay attention to your thinking process. What patterns do you find there?

Discern Patterns

Posted on by Denise Gaskins

I’m almost done rewriting the Standards for Mathematical Practice into student-friendly language.

They say mathematics is the science of patterns. So here’s…

Math Tip #7: Discern Patterns.

  • Look for patterns in numbers, shapes, and algebra equations.
  • Notice how numbers can break apart to make a calculation easier.
  • Number patterns morph into algebra rules.
  • Adapt math situations to make the structure clear. (For example, by adding new lines to a geometry diagram.)
  • Step back from a situation to see it from a new perspective.
  • Try to find simpler patterns within complex equations or diagrams.
  • Not all patterns continue forever. Test your patterns. Can you trust them?

Exciting New Homeschool Math Program

Posted on by Denise Gaskins

Homeschooling friends, check out this new homeschool math program that’s fun, rigorous, and engaging — a delightful, hands-on course that helps parents (and their children) understand math.

Introduction to Cuisenaire Rod Structures Course

I had the privilege of previewing this class as Sonya and Lacy put it together. I highly recommend it to anyone who struggles with math, or who wants to take a non-traditional approach.

By focusing on making sense of number relationships, and by teaching algebra before arithmetic, this course provides a stress-free path to rich mathematical mastery.

And for all they provide, including weekly live workshops and a slew of printable math journal pages that prompt deep thinking, the price is a steal!

Say What You Mean

Posted on by Denise Gaskins

Continuing my project of rewriting the Standards for Mathematical Practice into student-friendly language.

Here’s my version of SMP6…

Math Tip #6: Say What You Mean.

  • Words can be tricky, so watch your language.
  • Label drawings and graphs to make them clear.
  • If you use a variable, tell what it means.
  • Care about definitions and units.
  • Pay attention to rules (like the order of operations).
  • Use symbols properly (like the equal sign).
  • Understand precision. Never copy down all the digits on a calculator.
