Dr. Cane is a lifelong educator. Born in France, he later became an American citizen and raised bilingual children. He has taught in multiple countries, including North Africa, France, and the United States, and holds a PhD in literature from the University of Michigan. For much of his career, he taught French literature at institutions such as Oberlin College and Occidental College.


In his 50s, Dr. Cane made a significant career shift and became a math teacher. Motivated by dissatisfaction with how math was being taught in American schools—particularly its emphasis on memorizing formulas and procedures—he returned to school to earn math teaching credentials. He went on to teach math in a predominantly minority high school in the Los Angeles Unified School District until he retired.


A pivotal moment for Dr. Cane came from helping his own child with math homework, where he observed that students were expected to memorize formulas (such as the perimeter of a rectangle) rather than deeply understand concepts. This experience led him to critique procedural teaching, which he believes overloads students with disconnected rules and undermines genuine understanding.


He embraced a new method of teaching math and called it, “Teaching to Intuition.” This technique emphasizes using students’ natural reasoning and everyday understanding rather than rote procedures. He shared an example involving a vertical number line instead of a horizontal number line and visual “bubbles” to teach integer addition, noting that even a seven-year-old could quickly and successfully grasp the concept through this intuitive method. He explained, “I use a vertical number line and I use bubbles. Well, let me write the first [problem] negative 10 plus 3. I put my pen behind each number and circle the number and the sign in front of it.” Using this approach helps students understand how each number is connected to each “sign” or “operation”. Intuitively, this allows the student to grasp how to solve the problem using the correct order of operations. Unsurprisingly, he criticized common mnemonic devices like “Please Excuse My Dear Aunt Sally” for teaching order of operations, arguing that they oversimplify, sometimes mislead students, and distract from true mathematical understanding.


As a math educator, I find Dr. Cane’s approach useful and beneficial to students. Although I personally majored in math in college, it was always an uphill battle. I was able to rely on procedures, formulas, and algorithms to get me through my four years, but math rarely made sense when it pertained to real-world applications. Instead of making valuable connections to get a deeper understanding, I relied on memorized procedures. Now that I am working with teachers as an education specialist, I realize that I never fully understood math and how it connected to applications that made sense to me. 


Like myself, not making connections is detrimental to learning math for most students. A Rand Corporation poll found that most middle and high school students tune out during their math lessons because they do not see the relevance in studying the subject (Schwartz et al., 2025). This is strongly because they cannot make connections that make sense to them. As a result, one in three middle and high school students do not see themselves as math learners, while another 25% lose interest in the subject that they once enjoyed. The survey indicates that there is a downward trend of students fully grasping math content which negatively impacts math identities and further supports the need for new approaches to teaching math.


I thought about Dr. Cane’s intuitive teaching model when I went to the grocery store the other day. I bought two boxes of noodles for $1.50 each, three bunches of broccoli for $1.10 each, and one bag of oranges for $3.50. As I prepared to pay, I mentally calculated the total to be sure I had enough money. Intuitively, I knew the noodles would cost $3.00, the broccoli would cost $3.30, and the oranges would cost $3.50. It felt natural to multiply $1.50 by 2, $1.10 by 3, and then add $3.50. This type of reasoning happened automatically, without relying on memorized rules or mnemonics. By bringing this kind of intuitive thinking into the classroom, students can develop a deeper understanding of mathematical relationships and apply the order of operations in a more meaningful and logical way.


I acknowledge that intuitive teaching can be difficult for educators to adopt because change often feels threatening and challenges long‑held habits. Nevertheless, I can see how teaching math through common sense, familiarity, and intuition leads to deeper student understanding and engagement. Intuitive teaching is a concept‑driven approach to mathematics education, grounded in how people naturally think and make sense of the world. This powerful approach highlights the fact that we use math intuitively every day. When these real‑world connections are brought into the classroom, teachers can help make learning math both engaging and meaningful.

Dr. Edric Cane, a 90-year-old teacher veteran, currently lives near Sacramento, CA.

 

“Common sense math stands in contrast to knowing math mostly as something you learn from textbooks or teachers and are expected to memorize. Instead, you are helped to discover math more by answering questions than by being told. You learn from your own intuitive understanding, from your common-sense answers. Your knowledge belongs to you. It stands in contrast to a jumble of rules and procedures that clog your brain. It is liberating. The approach is significantly different than what is currently done. It is pretty close to a paradigm shift. It aims to affect dismal national statistics and help all enjoy math and welcome it as a natural dimension of their daily lives.”

H ave students choose (or suggest) a simple addition fact. 5 + 2 = 7. Have them give examples of that fact as applied to real things. Ask for full answers and write them down: 5 books + 2 books is 7 books 5 dollars + 2 dollars = 7 dollars 5 cats + 2 cats is 7 cats. Ask what math facts these answers illustrate. 5 + 2 = 7. These answers also are examples of a rule: Listen: “Books ,,, books ,,, books.” “Dollars … dollars … dollars.” “Cats … cats … cats.” This is the typical rhythm of additions and subtractions. Learn to hear it and to expect it. “We can only add (and subtract) numbers that have the SAME NAME.” It’s a fundamental rule of arithmetic with constant applications. It also makes sense: 5 + 2 = 7. But if we try to add 5 dogs + 2 cats, we don’t have 7 dogs. We don’t have 7 cats. But those cats and dogs are pets. We can decide to call them pets, and now we can add: we have 7 pets. Let’s apply the SAME NAME rule to PLACE VALUE. “What’s 1 thousand + 2 thousand?” “What’s 1 hundred + 2 hundred?” “What’s 1 thousand + 2 hundred?” 1 + 2 = 3. But we don’t get 3 of anything when we try to add 1,000 + 200. We can only say: “1 thousand 2 hundred.” Or we can change 1 thousand into 10 hundred. Now we can add: “10 hundred + 2 hundred = 12 hundred.” Now, the two numbers have the same name and we can add. The “SAME NAME” rule is a powerful rule of arithmetic. Math formulates it as a rule when it asks us to add mathematical objects: With fractions: “Add the numerators and keep the COMMON DENOMINATOR." “COMMON DENOMINATOR” is another way of saying “SAME NAME.” Check TOPICS “Fractions 1” to connect adding fractions with the rule that applies to anything we add. In algebra: “You can only add LIKE TERMS.” “LIKE TERMS” is another way of saying “SAME NAME.” Check “SAME NAME 2” for other details on the rule. Also “PLACE VALUE.” CLICK to download this article

We expect students to learn by answering questions. A version of that same approach consists in expecting students to learn from examples. We tell them, for instance, that 2/5 is: Another way of writing a division: 2 divided by 5. A quantity equal to the quotient of the division. 2 of something called a fifth. A proportion: 2 out of 5. Etc. We then take it for granted that they can generalize from these examples. “2/5 is 2 of something called a fifth.” They have no difficulty generalizing to “7/8 is 7 of something called an eighth.” Formulating the same knowledge in terms of “numerator” and “denominator” would be difficult to articulate and just as difficult to understand. Trusting students to generalize from examples is better math knowledge than a formulation of the legalistic version. Various versions of ASK don’t TELL and trusting students to GENERALIZE from EXAMPLES can be applied at all levels of mathematical instruction. CLICK to download this article

As teachers, we want students to know. So we routinely tell them what we want them to know or allow the textbook to tell them. Students get accustomed to being told what they should know. We expect them, and they expect, to memorize what they are told. This gradually builds up knowledge as a mass of memorized facts, rules and procedures that clog the brain. A very simple and powerful strategy turns that on its head. It can be applied at all levels of math instruction: ASK students instead of TELLING them. Teachers ask me to help explain to students why a large denominator does not mean a large fraction. This understanding is absolutely basic to any understanding of fractions. Let’s apply the ASK don’t TELL strategy. 1/2 One half. In how many parts do I divide the pizza? (2) 1/4 One fourth. In how many parts do I divide the pizza? (4) What about 1/8? In how many parts do I divide the pizza to get eighths? So is 1/8 larger or smaller than 1.4? (1/8 is smaller.) 1/8 is smaller than 1/4 but 8 is larger than 4. Can you tell me why? (Because I cut the pizza in 8 slices instead of just 4.) Students learn from their own answers. The knowledge is not a memorized rule, it is a practical experience. It belongs to the students. They learn something about fractions, and they also learn that knowing math is not about memorizing but about understanding. They soon learn to expect and enjoy that kind of knowledge. They learn to like math. CLICK to download this article

Operations on fractions are a topic that remains a challenge for many Middle School and High School students, sometimes all the way to remedial classes in Community Colleges. It shouldn’t be. First, a diagnostic. The rule for multiplying fractions is not often a challenge. Multiplying the numerators and multiplying the denominators makes sense. Adding and subtracting is the real challenge. Too often, “Add the numerators and keep the common denominator” becomes confused with the rule for multiplying. So, students add the numerators and add the denominators which gives the wrong answer. This is the most common error. The problem is entrusting the knowledge to memory. With no understanding, nothing protects the memorized rule from being mis-remembered. Hence that most frequent confusion with the rule for multiplication. On this important topic, we will propose overtime a number of short approaches. But many students are helped by just helping them make a connection between the rule for adding fractions and the familiar experience of adding anything else. It’s as simple as asking: What’s 2 dollars + 2 dollars? So, what’s 2 fifths + 2 fifths? What’s 5 books + 3 books? So, what’s 5 sixteenths of an inch + 3 sixteenths of an inch? What’s 9 cookies minus 3 cookies? So, what’s 9 tenths minus 3 tenths? No rules here. Just asking questions and a connection with common sense. CLICK to download this article
