Review and Giveaway

LPM-book-with-coffee-800There’s still time to enter the book giveaway at Our Home on the Range blog:

Here on the Range, I’m determined to establish an environment where math is not just numbers and answers. I firmly believe my children can learn all the math they want, when they’re ready, as long as they don’t convince themselves they can’t learn it, they don’t like it, or that it’s too hard. To reach this goal, math must be a regular part of our lives in a way that encourages conversation and exploration.

  • Let’s Play Math could be the very introduction a young family needs as they contemplate the first few years of homeschooling. First Son’s early years may have been completely different if I had read this book when he was five.
  • It could be a fantastic book for a family with a child that’s struggling (in homeschool or otherwise) with math. A few years ago, when First Son first showed signs of a potentially life-long hatred of all things numerical, reading this book may have helped me adapt the curriculum we were then using to meet his needs and enrich him. (We ended up switching and I’m happy with that, but I could have avoided quite a bit of angst.)
  • This book would be perfect for a parent who has always struggled with inadequacies in math or for someone like me, who always did just fine in math but never understood the claims of math’s beauty or fascination. I find myself excited to explore some of the resources the author has gathered together for my own growth and new challenges.

How to Update Your Let’s Play Math Ebook


I love how seeing math as a playful game can help even the busiest parents enjoy learning alongside their children.

My math books grew from more than a quarter-century of playing math with children — my own and those of our friends — at my house, at the library, in the park, and in group workshops. The kids and I learned from each other as we shared the adventure of learning mathematics.

Now that the publication dust has settled and the typos and formatting glitches have been sorted out, I’ve updated all the Let’s Play Math ebook files to match my shiny new, greatly expanded paperback edition.

Changes Include

Do You Need an Update?

If your version shows the family playing together on the cover, then you’re all set. The copyright notice should say “Ebook version 3.0.”

But if you have an earlier edition of Let’s Play Math, you will probably want to update to this new, revised edition. Be warned: this is a totally new file, so you’ll lose all your highlights and bookmarks. But the expanded version has SO many wonderful changes, believe me, it’s well worth the inconvenience.

The following instructions are for If you bought your book somewhere else, check the book dealer’s webpage — if the new cover (above) is showing, then they have the updated file. Find the Customer Service section of their website and follow their procedure.

Amazon Policy Change

I’ve asked Amazon to release the new ebook files to everyone who bought the earlier edition — as used to be their standard policy. But they’ve had too many complaints about people losing their bookmarks, so they no longer issue updates except by customer request.

The only way to get the updated file is to contact Customer Service and ask for it yourself.

Step by step instructions:

  1. Click the contact Customer Service link. Log into your account.
  2. Under “What can we help you with?” click the option “Digital Services.”
  3. Under “Tell us more about your issue,” click “Kindle eBooks” and then “Something else.”
  4. Under “Enter short summary of issue,” copy and paste the following text:
    I bought the ebook Let's Play Math (ASIN B0095POAX4). This book has recently been updated with new material. Would you please send the updated ebook files to my account? Thank you.
  5. Choose how you want to be contacted. I always pick “Email,” but you can pick a more immediate option if you like.

And then wait for the support people to do their magic. You should get the new file within 24 hours.

What About the Paperbacks?

What if you got a bad copy of a paperback book?

The machines that print POD (Print On Demand) books — like my math book or my daughter’s fantasy novels — are basically giant computer printers. As everyone knows, printers get glitches. And the humans who take a book off the machine and put it in a shipping box won’t necessarily notice the mistake.

If you ever get a messed-up copy of my math paperbacks (or any book by anyone, for that matter), you can always contact customer service to have it replaced.

Just follow the same steps as above, but choose the options that make sense for whatever complaint you have. Or if you didn’t buy from Amazon, then find the Customer Service section for whatever book dealer you used, and follow their procedure.

Let’s Play Math Paperback Edition Now Available


Finally, the revised and much-expanded paperback edition of Let’s Play Math: How Families Can Learn Math Together—and Enjoy It is finished and loaded up on Amazon worldwide. Other bookstores will follow as soon as they update their files.

My book shows you new ways to explore math as a family adventure:

  • Introduce your kids to the “Aha!” factor, the thrill of solving a challenging puzzle.
  • Help them build thinking skills with toys, games, and library books.
  • Find out how to choose math manipulatives, or make your own.
  • And learn how to tackle story problems with confidence.

True mathematical thinking involves the same creative reasoning that children use to solve puzzles. Let’s Play Math turns math into a learning adventure for the whole family. Your children will build a stronger foundation of understanding when you teach math as a game, playing with ideas.

Understanding Math: Conclusion

Click to read the earlier posts in this series: Understanding Math, Part 1: A Cultural Problem; Understanding Math, Part 2: What Is Your Worldview?; Understanding Math, Part 3: Is There Really a Difference?; Understanding Math, Part 4: Area of a Rectangle; Understanding Math, Part 5: Multiplying Fractions; and Understanding Math, Part 6: Algebraic Multiplication.


Earlier in this blog post series, I gave you three middle-school math rules. But by exploring the concept of rectangular area as a model of multiplication, we discovered that in a way they were all the same.

The rules are not arbitrary, handed down from a mathematical Mount Olympus. They are three expressions of a single basic question: what does it mean to measure area?

There was only one rule, one foundational pattern that tied all these topics together in a mathematical web.

What Is Your Worldview?

Many children want to learn math instrumentally, as a tool for getting answers. They prefer the simplicity of memorizing rules to the more difficult task of making sense of new ideas. Being young, they are by nature short-term thinkers. They beg, “Just tell me what to do.”

But if we want our children to truly understand mathematics, we need to resist such shortcuts. We must take time to explore mathematics as a world of ideas that connect and relate to each other in many ways. And we need to show children how to reason about these interconnected concepts, so they can use them to think their way through an ever-expanding variety of problems.

Our kids can only see the short term. If we adults hope to help them learn math, our primary challenge is to guard against viewing the mastery of facts and procedures as an end in itself. We must never fall into thinking that the point of studying something is just to get the right answers.

We understand this in other school subjects. Nobody imagines that the point of reading is to answer comprehension questions. Back to SchoolWe know that there is more to learning history than winning a game of Trivial Pursuit. But when it comes to math, too many parents (and far too many politicians) act as though the goal of our children’s education is to produce high scores on a standardized test.

What If I Don’t Understand Math?

If you grew up (as I did) thinking of math as a tool, the instrumental approach may feel natural to you. The idea of math as a cohesive system may feel intimidating. How can we parents help our children learn math, if we never understood it this way ourselves?

Don’t panic. Changing our worldview is never easy, yet even parents who suffer from math anxiety can learn to enjoy math with their children. All it takes is a bit of self-discipline and the willingness to try.

You don’t have to know all the answers. In fact, many people have found the same thing that Christopher Danielson described in his blog post “Let the children play” — the more we adults tell about a topic, the less our children learn. With the best of intentions we provide information, but we unwittingly kill their curiosity.

  • If you’re afraid of math, be careful to never let a discouraging word pass your lips. Try calling upon your acting skills to pretend that math is the most exciting topic in the world.
  • Encourage your children to notice the math all around them.
  • Search out opportunities to discuss numbers, shapes, symmetry, and patterns with your kids.
  • Investigate, experiment, estimate, explore, measure — and talk about it all.

The Science of Patterns

Patterns are so important that American mathematician Lynn Arthur Steen defined mathematics as the science of patterns.

As biology is the science of life and physics the science of energy and matter, so mathematics is the science of patterns. We live in an environment steeped in patterns — patterns of numbers and space, of science and art, of computation and imagination. Patterns permeate the learning of mathematics, beginning when children learn the rhythm of counting and continuing through times tables all the way to fractals and binomial coefficients.

— Lynn Arthur Steen, 1998
Reflections on Mathematical Patterns, Relationships, and Functions

If you are intimidated by numbers, you can look for patterns of shape and color. Pay attention to how they grow, and talk about what your children notice. For example, some patterns repeat exactly, while other patterns change as they go (small, smaller, smallest, or loud, louder, loudest).

Nature often forms fractal-like patterns: the puffy round-upon-roundness of cumulus clouds or broccoli, or the branch-upon-branchiness of a shrub or river delta. Children can learn to recognize these, not as a homework exercise but because they are interesting.

Math the Mathematician’s Way

Here is the secret solution to the crisis of math education: we adults need to learn how to think like mathematicians.

For more on what it means to think about math the mathematician’s way, check out my Homeschooling with Math Anxiety blog post series:

As we cultivate these characteristics, we will help our children to recognize and learn true mathematics.
