Screens are destroying our children's minds! Or are they?

Honestly, I have no idea. I do know that parents of every generation are terrified of the new technology and games their children love. A century ago, columnists wrote polemics against the scourge of chess, which was sweeping the nation at the time. In the 19th century, British families fretted that their young girls were spending too much time reading the novels of Jane Austen, which are now considered part of the canon. Even written language was scoffed at by ancient intellectuals, who believed that writing was a crutch for people who couldn't memorize everything they needed to know.

On the other hand, I get freaked out when I leave my kids watching Peppa Pig on Youtube, only to return 20 minutes later to find them watching poorly animated train videos dubbed in Russian. How did they even find those?

So I have a skeptical outlook on the value of screen time. It's probably not hurting my kids too much, but it's probably not helping either. And the math apps I've found have mostly been underwhelming. Mostly, these apps focus on repetitive practice of math facts, which doesn't exactly sound like a rich mathematical experience.

But Dragonbox Numbers is a different sort of math app. I was skeptical at first, but the game won me over with its well-designed activities that get kids thinking about the relationships between numbers, rather than simply drilling math facts.

If your child is in Pre-K through 1st grade, I highly recommend this game. Note that Dragonbox has several other apps for older kids, but I haven't played those yet. I am talking specifically about Dragonbox Numbers.

## How to Play

Dragonbox Numbers is built around little blocks called Nooms, which are meant to represent the numbers from 1 to 10. Nooms can be smooshed together to make bigger Nooms, or cut into smaller pieces. The app has three main sections: Puzzles, Ladders, and Run.

Puzzles are activities where kids make Nooms of different sizes and add them to a stencil, much like adding pieces to a puzzle. In this section kids start to build an intuition for how numbers can be combined.

Ladders are secretly puzzles as well! Your child needs to make a Noom of a certain height in order to reach the star. As the ladders become more challenging, kids can't simply add 1 over and over. They must plan ahead, thinking about other ways that Nooms can be added to build numbers.

Run is a Mario-style game where your child jumps to capture stars and coins. The height of the jump corresponds to the number your child presses, so she gets a visual representation of how the numbers compare to each other

Check out the video below to see how even a toddler can interact with the simple interface as she solves a puzzle.

## Where's the Math?

The game is riddled with math, of course, all focused on helping kids build an intuition for how the basic building blocks of math, numbers, work together. If you have a child in preschool or at the beginnings of elementary, they need tons of opportunities to see how numbers can be represented, combined, and split apart.

I like the Dragonbox method of representing bars of different heights. Mostly, kids interact with numbers as a set of objects, so they think of 3 as "three blocks" or "three circles." When kids see numbers represented as lengths, they begin to understand how numbers can be used to measure objects, not simply to count them. They might see 3 and think "something that is three blocks tall."

As your child moves through the app, they will encounter more and more numerals (the numbers 1, 2, 3, and so on). But repeatedly, they will be asked to connect those numerals to another representation of a number. The more connections your child has between numerals and other representations, the more automatic their reasoning with numerals will become.
