A key part—though surely not the only part—of early-grades math is ensuring students get the basic arithmetic functions down and, beyond that, making sure they’re able to swiftly and automatically ...

Solving arithmetic problems, even simple subtractions, involves mental representations whose influence remains to be clarified. Visualizing these representations would enable us to better understand ...

You can probably think of a time when you’ve used math to solve an everyday problem, such as calculating a tip at a restaurant or determining the square footage of a room. But what role does math play ...

Now, I taught junior high school math for three years, so when I saw this simple equation, I knew I could solve it quickly and I did just that. Before you see my answer, go ahead and solve it for ...

Playing with arithmetic can lead us to unexpected and profound discoveries that point toward deeper mathematics and sometimes even deeper science. We solved our last Insights puzzle by performing some ...

Pre-algebra is more than just a set of math topics—it’s the bridge between basic arithmetic and the deeper logic of algebra. Mastering it builds the confidence and skills needed for high school math, ...

Concepts covered in this course include: standard functions and their graphs, limits, continuity, tangents, derivatives, the definite integral, and the fundamental theorem of calculus. Formulas for ...
