When you were in school, you probably learned to multiply large numbers using the standard algorithm method . Students still learn that method today, but they also learn a variety of other options to help them truly understand the process. One of these is area model multiplication, which seems more complicated at first but actually really benefits kids.
Let’s take a look at what this method is, why it matters, and how to teach it. What is area model multiplication? The area model method is based on the simple equation used to find the area of a rectangle: the length times the width equals the total area (LxW=A). Students usually start by learning simple arrays for single-digit multiplication, demonstrated by this anchor chart from Primary Punch.
As students proceed to more complicated equations, the area model becomes more complex. As students work with higher numbers, the box model expands to include each place value. Why do we teach the area model? Area Model Multiplication Activities 1. Exploding Dots | G'Day Math. A global phenomenon is underway. Pure math joy is sweeping the planet! Learn about the phenomenon here.
Over a 7.4 million students and teachers from 170 different countries and territories have experienced the uplifting joy of Exploding Dots. 96.8% of teachers agreed or strongly agreed that Exploding Dots helped students see mathematics as more approachable, 96.6% as more enjoyable, 96.1% as making sense, and 93.1% as helping students be more confident in mathematics. 75.5% of teachers said that Exploding Dots changed their own perception of mathematics in some way with 97.7% agreeing or strongly agreeing that Exploding Dots made mathematics more enjoyable, 97.3% as more approachable, and 96.0% as more understandable.

Opinion: Math scares your child's elementary school teacher — and that should frighten you. American students remain stumped by math. The 2019 scores for the National Assessment of Educational Progress test — known as NAEP — were published last month, showing that performance for fourth- and eighth-graders hasn’t budged since 2009.
That’s a year after the National Mathematics Advisory Panel, convened by President George W. Bush, concluded that American math achievement was “mediocre.” The panel offered dozens of ideas for improvement, leading with the common-sense suggestion to strengthen the elementary math curriculum, which it deemed diffuse, shallow and repetitious in many schools. Consider why American kids struggle. The National Mathematics Advisory Panel concluded U.S. students have adequate knowledge of the first two, but not the third. For example, a middle schooler might be able to calculate 0.77 x 0.63, but not immediately see before she calculates that the product will be less than 0.77. The equal sign is another mathematical concept that’s often misunderstood. "Place Value in Primary Sources Activity" by Cynthia J. Huffman Ph.D. "Emmy Noether and Modular Arithmetic Activity" by Cynthia J. Huffman Ph.D. The Crow and the Pitcher Rate of Change | No. 2 Pencils.
The Crow and the Pitcher is based on an Illuminations lesson. I used it as the introduction to linear functions to demonstrate a real-world rate of change for my students. The lesson is based on Aesop's Fable, "The Crow and the Pitcher. " I began the lesson by reading the fable to them. You can also show this video from Sesame Street if you do not have the book. In looking for a video of the book, I came across this experiment. I borrowed graduated cylinders and beakers from the amazing science teacher on my team. Students were in groups of two to three. Students added one pebble at a time and then put a data point on their table. I like the way this group would predict how much the water level would rise before they dropped the pebble in. Once they added seven pebbles, I had them share how many it would take to get to 100 mL. Most groups' data was a rate of change of 2 mL/pebble.
The Illuminations lesson continues to fill the container with more marbles to determine domain and range. Counting Principles - Counting and Cardinality - Make Math Moments. How To Use Math Is Visual - Math Is Visual. So I keep saying “Math is visual. Let’s teach it that way!” That’s great and all.
But what if you’re not sure where to start? You’ve come to the right place! While you are free to use the MathIsVisual.com website and resources in any way you feel would be most useful, I’d like to take a moment to share how I visualized this tool being used by teachers with their students in a classroom setting as well as parents with their children at home. 1. Every Math Is Visual video prompt takes a visual approach to help model for teachers, parents and students an intuitive way to think about a mathematical idea. The goal is to lead the viewer down a very carefully planned inquiry pathway so the construction of conceptual understanding will take place along the way while working towards the development of procedural fluency over time. 2. Consider pausing the video as often as useful and/or necessary to ask your students or children what they notice and what they wonder. 3. 4. Wow, pretty amazing, right?

This story was originally published in our Jan/Feb 2023 issue as "A New Solution to an “Impossible” Math Problem. " Click here to subscribe to read more stories like this one. Geometry students are taught that squaring the circle — using a compass and straightedge to draw a square with the same area as a given circle — is impossible. But in February 2022, a trio of mathematicians who couldn’t resist an impossible challenge presented the closest solution yet for the problem. Squaring the circle has a history of failed attempts dating back at least to the ancient Greeks. And in 1882, French mathematician Carl Louis Ferdinand von Lindemann proved that pi is transcendental, which means, among other things, that it’s impossible to draw a line of that length.
But what if you abandon the compass and straightedge? The newly developed method describes a set of simple rules — simple for mathematical recipes, anyway — for this ridiculously complicated jigsaw puzzle. How to Make a Flexagon Christmas Card - Maths Careers. Resource Alert: Nix the Tricks!
