We’ve been looking at Deans for Impact’s white paper, “The Science of Learning,” which summarizes cognitive science research and its implications for teachers (and homeschoolers). The paper poses six key questions that help us to apply the principles of science in teaching our children.

This week, let’s explore how students learn and retain new information.

Because if we want our children to be able use what we teach them, the first step is to help them remember it.

The Science of Learning 1: Understanding

We all want our children to thrive, to grow, to learn, to succeed in school and in life.

Cognitive science focuses on the “learning” part of life, studying how people acquire and retain information and then incorporate it into their understanding of the world. Earlier this year, Deans for Impact published a new edition of their white paper, “The Science of Learning,” summarizing cognitive science research and its implications for teachers.

What do we know about how students learn, and what does that mean for how we teach?

    That’s what The Science of Learning seeks to answer.

      The Science of Learning summarizes existing cognitive-science research on how students learn and connects it to practical implications for teaching. The report is a resource for teacher-educators, new teachers, and anyone in the education profession who is interested in how learning takes place.

      In this series, we’ll go through Deans for Impact’s six key questions and learn how to apply the principles of science in teaching our children. First, let’s explore how students understand new ideas.

      Because if we want our children’s learning to stick, our focus must always be on helping them make sense of things.

      How Do Students Understand New Ideas?

      Principles from The Science of Learning:

      • Students learn by connecting new knowledge to what they already know.
      • Students have limited working memory capacity that can be overwhelmed if given too much information at once or if tasks are cognitively too demanding.
      • Cognitive development does not progress in a fixed sequence at age-related stages. Understanding does not happen all at once or just one time; the mastery of new concepts happens in fits and starts.

      Tips for Teachers

      • Encourage students to remember what they’ve already learned, and help them connect new knowledge to old.
      • Use stories, activities, and visuals that clearly relate to the concept being studied. Avoid distracting clutter that is merely decorative.
      • When working example problems, discuss the reasoning behind each step and help students make connections.
      • Don’t limit students to “grade level” ideas, but wonder about big concepts.
      • Don’t assume that learning something once is enough. Repetition and reinforcement make learning solid.

      My Comments

      We make sense of new ideas by connecting them to things we already know, by recognizing relationships.

      I appreciate the reminder of how important background knowledge is to new learning. It’s easy for me to jump straight into the new material, thinking that’s the interesting part of a lesson, but I need to let my students orient themselves by remembering what we’ve done before.

      Just as I begin a history read-aloud with, “Tell me what happened last time,” I can begin a math lesson with, “Remind me of what you know about division.” My goal is not to make connections for my students, but to open their eyes so they can see the relationships for themselves.

      Try This Today: Number Webs

      For each post in this Science of Learning series, I’ll share an activity idea that gives you and your children a way to put it into practice. Today, let’s play with relationships and see how many connections we can find between math ideas by creating Number Webs.

      For best results, get a large whiteboard or a sheet of poster-size paper.

      Write a number or math expression in the center of your space. Then take turns writing equivalent expressions, other ways to say the same thing. Draw lines to show how these new expressions branch out from the original to form families of related math.

      For example, if you begin with the number five, branches might include:

      • 1+4, 2+3, etc.
      • 10÷2, 15÷3, and so on
      • 20/4, 50/10, etc.
      • What else can you think of?

      As you build your number web, each transformation will spark new ideas. You can create branches off the branches. For example, you could shoot off from 15÷3 with an expression like (5+5+5)÷3, or (7+8)÷(9−6).

      For each bit of math you add, be prepared to explain why it fits in the family you chose, or how it’s different from the others and needs to start a new branch. Often an expression could fit in several places, and players may argue for their own point of view. But the player whose turn it is has the final say where to place his or her creation.

      Instead of (or in addition to) writing in a new expression, players may draw in a line that connects it to an expression on a different branch. Numbers relate to each other in various ways, and there is almost always more than one way to think about linking them. For example, you might join the division expression 15÷3 with the fraction 15/3 and the multiplication (⅓)×15.

      Don’t worry about keeping your Number Web neat and systematic. Explore and let the connections get a bit wild. There’s always another relationship to discover.

      Conversion Factors: How Old Are You in Nanoseconds?

      Homeschool Memories

      [Based on a problem I made up for my co-op students, once upon a time…]

      Conversion factors are special fractions that contain problem-solving information. Why are they called conversion factors?

      • “Conversion” means change, and conversion factors help you change the numbers and units in your problem.
      • “Factors” are things you multiply with. So to use a conversion factor, you will multiply it by something.

      Charlotte Mason's Living Math ebook editionIn my new book, Charlotte Mason’s Living Math, I encourage families to explore the world of math by asking big, open-ended questions.

      [Now available exclusively in my Playful Math Store! Ebook only at the moment, but print editions are coming soon.]

      Here’s an example of such a question, an excerpt from my earlier book, 70+ Things To Do with a Hundred Chart: Number, Shape, and Logic Activities from Preschool to Middle School.

      Have fun exploring math with your kids!

      Make Your Own Nim Games

      tower of rocks on a beach

      Nim is a pure strategy game for two players. On each turn, players remove an option until finally no choice remains.

      Game options might include:

      • How many stones to take from a pile.
      • Which position to claim on a gameboard.
      • How far to count in a given sequence.

      The rules can vary at the players’ whim (as long as both players agree). How many possibilities do you start with, what are the rules for removing options, and how do you win or lose the game? Everything is open to change. And with every tweak, players must reanalyze their strategy.

      Playful Math 184: Carnival of Living Math

      Playful Math Carnival 184

      Welcome to the 184th 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.

      With all the links, a blog carnival can feel overwhelming. Bookmark this article, so you can take your time reading the posts.

      “Living math” means bringing our children face-to-face with the big ideas of mathematics to help them develop their reasoning skills. When the ideas of math come to life for our children, their minds delight in seeing how numbers and shapes connect to each other and exploring these relationships.

      Scattered between the playful math links below, you’ll find quotations from my new book Charlotte Mason’s Living Math, along with several paintings of children playing and learning which I considered for the book but ran out of room.

      “The lesson” by Rafael Frederico, 1895.

      By tradition, we start the carnival with a puzzle/activity in honor of our 184th edition. But if you’d rather jump straight to our featured blog posts, click here to see the Table of Contents.

      Book, Charlotte Mason's Living MathOne of the stretch goals for my Charlotte Mason’s Living Math Kickstarter campaign is to add a math journaling prompt to the end of each chapter. So, I’ve been playing around with ideas to get readers writing.

      Since the book’s all about how to build mathematical reasoning, I’m looking for ways to prompt creative thinking and flexibility in math calculations.

      Check Out the Kickstarter

      I found some fun ideas in Guy Gattegno and Martin Hoffman’s Handbook of Activities for the Teaching of Mathematics (which you can download here), including the following riff off a puzzle created by Lewis Carroll.

      Geometric Math Art, Recovered

      Geometric pattern by Denise Gaskins

      I’ve been updating my old book files to a new publishing program, and in the process discovering anew how often websites change and disappear. So frustrating!

      Thankfully, the Internet Archive keeps some things that we can look back at. It doesn’t always work, but today it came to the rescue and let me recover the wonderful workbook from the Metropolitan Museum of Art, Islamic Art And Geometric Design, plus some of the pattern pages at the old School of Islamic Geometric Design.

      I reference these pages in my Geometric Coloring Designs series (available at my Playful Math Store), so I was glad to find they weren’t lost forever.

      Math Art = a great way to spark energy when your students hit the mathematical doldrums.

      Two Hands-On Craft Projects

      photo: Cutting a paper square

      Here are a couple of fun foldable projects to try with your kids.

      Both of the projects below start with squares of paper. Do you know how to convert any piece of paper into a square? Here are two methods.

      • Can you tell why they work, how each method creates a true square?
      • What if you didn’t have a rectangular page to start with — could you still create a square?

      Happy Pythagorean Triple Day!

      Pythagorean Theorem demonstrated with tangrams

      Thursday is Pythagorean Triple Day, one of the rarest math holidays.

      The numbers of Thursday’s date: 7/24/25 or 24/7/25, fit the pattern of the Pythagorean Theorem: 7 squared + 24 squared = 25 squared.

      Any three numbers that fit the a2 + b2 = c2 pattern form a Pythagorean Triple.
