So since I first had my students play DragonBox last year, We Want to Know came out with a sequel, DragonBox 2. They are now branded as 5+ and 12+, as the original DragonBox is intended to introduce the idea of algebra and solving equations to someone unfamiliar with it, while DragonBox 2 is meant to deepen the equation-solving toolbox of someone already familiar with solving equations, allowing them to deal with more complex equations.

I was trying to decide which one to use with my class this year. It seemed like DragonBox2 would be better at first glance, because I teach high schoolers: we have seen basic equations, and now we need to kick it up a notch. But I wound up going with DragonBox 1, saving the sequel for a handful of students who blazed through it and were advanced. I know I made the right choice because of situations like I tweeted about:

There were several students who could solve the first level (one of the hardest in the game), but not the second, which came later. This showed me that there was something about the structure of an equation that wasn’t getting through and that we needed to work on it.

In DragonBox 1, you only really have four abilities: you can combine inverses into 0, you can divide a card by itself to get 1, you can add a card from the deck to the game (one on each side), and you can attach a card from the deck to another (multiplication/division), as long as you do it to every card in the level. In DragonBox 2, you can do new things like flip a card from one side to the other, divide a night version by a day version (leaving negative 1), combine like terms, factor out common terms, and treat complex expressions as single units to multiply/divide by.

Those are all good things to do, and someone proficient in algebra should be able to do those things. But I backed away from using it in class because it lacked the *why*. At the end of the first DragonBox lesson, I compile the notes students took while playing to make a comprehensive list of rules and abilities you have in the game. The one student who played DragonBox2 insisted that, in the game, you can slide a card from one side to the other. **No matter how much I pressed him**, he didn’t see that the card wasn’t sliding over, it was flipping/inverting.

And that’s what I was afraid of by using DragonBox2. These tools are important, but they have to be earned by understanding them. DragonBox2 gives them to you by completing previous levels, not necessarily by understanding how. At the least, in DragonBox 1, because you are stuck with the basics, you have to grapple with where the solutions come from. They can’t magically appear.

So while DragonBox2 is rated as 12+, I wouldn’t give it to any student who didn’t already have a firm grasp on the concept of equality. Maybe post-Algebra 1. Or at least not until much later in the year.

Comments on:"Intentions Change Approach (DragonBox 2 vs DragonBox 1)" (1)jeansaid:Hi James, great post! some ideas if it can help?:

– since we know that learning is social and very language based, we recommend to use DB as follows. 1) let kids play 20 mn 2) make a break (dance, sing or anything to relax) 3) gather kids around the chalkboard and let one kid at a time solve a puzzle. Key here is to let kids verbalize what they do and have a natural discussion about how to solve the puzzle. Ask the kids to put own words on objects and actions and describe what s going on.

Don´t explain anything yourself, but ask open questions. I think this process makes kids understand at a deeper level what they are learning in a very classical constructivist way.

DB is a tool to make kids manipulate math concepts, so that math is anchored in their reality. I strongly believe it is impossible to teach abstract concepts without rooting it in childrens experience (physical experience or known metaphors). DB lets create this experience and reality, but it is obvious it must be discussed and digested through social interaction!

– as it regards the why, since our game about equality is not developed, I encourage you to take equality separate before using the game. I can send you some simple ideas to introduce it before DB. Send me a mail for that.

– as it regards shifting to the other side, I would take a simple example with adding on both sides, and ask the kids if they notice what s going on. Make them discover that the sign has changed! Then I would let them play with the rule of flipping.

Dont hesitate to directly interact with me in this conversation : )
