Back to Basics: The Essence of the Mathnasium Difference

Principles of Math can come across confusing to students, especially when they are bombarded with multiple rules and confusing practices. Mathnasium focuses on introducing new subject matter with a consistent and knowable approach, allowing students to build upon a foundation of knowledge while understanding and adding new principles.

To begin Early in a child’s learning, values are expressed in groups of 10s:

• 10 pennies make a dime.

• 10 dimes make a dollar.

•   10 “one-dollar” bills make 1 ten dollars, and 1 ten–dollar breaks down to 10 “one–dollar” bills

• 100 pennies make a dollar.

• 100 dimes make ten dollars.

• 10 hundreds make a thousand.

• 1,000 thousands make a million.

Some things ”make sense” to cut in half: a candy bar, a piece of wood, numbers... Other things don’t: people, pennies, cars... To diagnose the correct approach, assess the subject matter. Use the examples below as guidance.

• If twice as many people as you expected come on a picnic, then you will need twice as much food.

But, if you are baking bread, twice the regular heat will not get the job done twice as fast.

• When you double the number of pieces, the size of each piece is half as much as it was. (This is the inverse relationship: when one thing goes up, the other goes down.)

Contrary to its reputation, Math is not all numbers, in fact, word prefixes play a large role in setting the numerical value. Take these examples:

• “mono–”means 1: The monorail at Disneyland runs on 1 rail.

• “bi–” means 2: A bicycle has 2 wheels.

• “tri–” means 3: a Triceratops has 3 horns.

• “qua–” means 4: a quartet has 4 players

• “dec–” means 10: a decade is 10 years

• “cent–” means 100: percent means “for each 100”

• “mil–” means 1,000: a millennium is 1,000 years—a mile is “1,000 paces”


Finally, I touch on a few points of knowledge for your student (if this is for parents, “parents have kids… teachers have student) that will assist him or her build the base for understanding the previously dissected, whole and parts method.

• A quarter of an hour is 15 minutes (not 25).

• There are 4 quarts in one gallon. A “quart” is a quarter of a gallon.

• Whole basketball and football games have 4 quarters.

• Four quarters make a whole dollar.

• One half dollar is the same as 2 quarters.

• Half-time in a basketball game comes after 2 quarters.

These basic understandings set the cornerstone for laying the foundation of knowledge to continually build and evolve your student’s mind, the Mathnasium way.

The Importance of Telling Time in a Digital Age

Most students today grow up with tablets, cell phones, and laptops at their fingertips. These tools can aid learning, but they can also encourage laziness. With the Mathnasium Method, students are taught to use their brains, not their iPads. I’ll demonstrate this by using an example of how kids can learn to tell time.

By second grade, most students can count by 1s, 2s, 5s, and 10s, up to at least 200. We can make it easy for them to “tell time” by expanding this to include counting by 15s, 20s, and 30s, as well as counting by 10s starting at any number (7, 17, 27...).

When you stop and think about it, all points on the clock can be reached quickly by counting various combinations of 30, 20, 15, 10, 5, and 1.

When students are taught these counting skills before they deal with clocks, learning how to tell time is a very straightforward process. Without these skills, it’s quite a chore.

Here’s a way to teach students these skills:

• Counting by 10s starting at any number goes like this: start at 23: twenty–three (23), thirty–three (33), forty–three (43)... as though you are just counting by 10s, except that you say the three. So, counting by 10s starting at 37 becomes thirty–seven, forty–seven, fifty–seven...

• Counting by 15s can be done by counting by 10 and then counting by 5: 15 + 15 = (15 + 5) + 10 = 20 + 10 = 30. 30 + 15 = (30 + 10) + 5 = 40 + 5 = 45. 45 + 15 = (45 + 5) + 10 = 50 + 10 = 60.

• Counting by 20s is almost the same as counting by 2s: 0, 20 (twenty), 40 (forty), 60 (sixty), 80 (eighty)...

• Counting by 30s should be presented after the child can count by 3s. Counting by 3s is similar to counting by 2s. Counting by 2s can be explained as, “Say the number, skip the next number, say the number...” Then counting by 3s becomes: “say a number, skip the next two numbers...” Now counting by 30s becomes: 0, 30 (thirty), 60 (sixty), 90 (ninety)...

With the help of parents or teachers, telling time can be introduced to a student as early as kindergarten. The sooner students learn to count quickly using the above methods, the sooner they’ll be using terms like “quarter till” and “half past.”
