In math, what are “exploding dots?” I work with students and one of them is taking a course called Exploding Dots. I thought it sounded fun so I looked it up—I’m having trouble even understanding the concept of it, much less how it actually works.

It’s a method of teaching/learning basic arithmetics like addition and multiplication. It works the same way that arithmetics work, they are just a way of visualization which students supposedly may find more intuitively clear.

i got curious and looked this up. from what i understand, exploding dots is a more visual method of explaining regrouping in math. 10 dots combine and explode into 1 dot, but in the box to its left.

It’s an interesting way to visualize the structure of numbers in various bases. It lends itself well to addition and subtraction but gets somewhat obscure when it comes to multiplication and division.

It also offers some interesting insight into infinite series, polynomials, and rational bases (base 3/2 for example)

As a maths teacher (primary), I’ve found it quite a useful intervention for explaining base 10 and how regrouping works to children who dont seem to understand manipulative like Dienes. Furthermore, been great way getting class to understand how base 3 would work for instance. Really refreshing, geeky challenge writing numbers in different bases
