The event description for Write it, Do it has been the same for many years. At the C level, it's done in teams of two. One team member is given a structure built from some sort of construction materials, which may be anything from toys (like legos) to craft materials (Popsicle sticks, pipe cleaners) to lab equipment. That team member has 25 minutes in which to examine the structure, without touching it, and write instructions for how to build it. Writers can use any numbers or symbols that can be typed on a standard keyboard by pressing one button, or one button in combonation with the shift key, and must define all abbreviations. Then the other team member is given the instructions and a set of unassembled parts (sometimes including extras), and has 20 minutes to try to recreate the original structure as accurately as possible. Scoring is based on the number of correct connections.


There are many different ways to approach this event. It is important that you find the strategy that works best for you and your partner.

The key to this event is practice. It is advised that you practice both writing and doing with your partner to identify certain good and bad elements of you or your partner's writing. As you practice, it will become apparent who is the better 'writer' and who is the better 'doer.'

Developing General Rules

As your practice, you may want to develop a set of 'rules' for your writing. This may include terminology for describing the relative positions of your structure, or a "directional" system to describe the direction which certain pieces point or face.

However, it is very important that these rules are general in nature. Excessively complicated or specific rule systems may confuse you or your partner and may also be interpreted as 'code' by event supervisors. As this is a highly subjective event, you will want to avoid the suspicion of event supervisors. Also, per Write It Do It rules, any words used out of their standard definitions must be defined.

Describing Characteristics of Building Materials

You should also come up with some standard or easy (but not code-like) way of describing characteristics of building materials. For instance, what will you call the little buttons on the tops of Lego pieces? Be careful not to have the same word for two different things, as that can be very confusing for the person building! You will probably find that some abbreviations are particularly useful to have, such as words and terms for different colors, sizes, shapes, lengths, and so forth. (Of course, some of these will be dependent on your building materials, and some won't.) Words like "piece" and "attach" are also good candidates for abbreviation. You may use a lot of abbreviations or just a few depending on how systematic your approach is. (Do remember you must list all abbreviations at the top of your paper during the event, so if you have to many, you may waste too much of your time writing abbreviations. Sometimes writing full words fast is a good option, but keep it NEAT!!!)

Bear in mind that this is a very subjective event, and a lot of the interpretation is left up to the people running it. Both partners should ask the event runners about their specific scoring style, as you will find it varies greatly from competition to competition. For instance, at the 99 nationals, the scorers viewed the structures in layers, starting from the bottom up. As soon as a layer was wrong, they stopped scoring, because they considered all the connections above that layer to be incorrect. Knowing things like this might affect the way you budget your time or how much attention you pay to detail. And even if they don't want to answer your questions, it can't hurt to ask - that way you won't end up later thinking "if only I had known!"

Sample Team Strategy

Some sample strategies you may wish to employ are given below to help get you started. This is by no means a complete list of ways to approach this event, but rather methods that have been tried and tested. Most have won medals at the national competition in both divisions B and C.

1. Decide how to approach the horizontal plane, as well as the vertical plane. For instance, for objects all on the same level (horizontal plane), you may choose to use North/South/East/West. If using this system, it is highly advised to divide your grid into sixteenths. That is, rather than just simply N or W, use NNW or WSW. This yields a much higher degree of accuracy on the placement of tricky pieces. Another method is the compass. Decide, for instance, that 0 degrees is as far away from the builder as possible. Then, going clockwise, count up to 359 degrees. So, for instance, an object to the south west of another would be at approximately 225 degrees. This provides for very very accurate measurements, assuming both you and your partner have the same perspective, and both know how to count to 360 (harder than it sounds sometimes). The third commonly used reference frame for objects is the clock face. Far away from you is 12:00 and work your way around. So an object to the south west of another one would be maybe 7:30 (rather than going to the nearest hour, an object can sometimes be in between. Therefore you may wish to go to quarter hours. That is, 3:15 would be 1/4 of the way between 3:00 and 4:00.)

2. The second important thing is to come up with a standard set of definitions for everything. Make sure you know what to call everything. And if you encounter something new in competition, pick a name that makes is obvious what you're referring to. Preferably a short one that doesn't take long to write repeatedly.

3. The next key is figuring out distances with your partner. As much as I would love it to be so, the things at competition will most likely not all be in one fluid piece all connected together. Therefore, you're going to have to know how to describe a piece that's out making its own island away from the main structure. We've already covered the relative angle part in step 1. But saying something is 80 degrees (ENE; 2:30) from another object, really doesn't do you much good. UNITS are always important! A foot away? Across the room? How far? This is where it gets interesting between you and your partner. You can always stick to standard measurements. I recommend cm, because they're Metric and spaced nicely for estimations. Remember to define 'cm' as an abbreviation if you use it though! The key to this though is making sure you and your partner can estimate lengths the same. It doesn't matter if you're both accurate, you just have to be consistently equally wrong!! This in itself requires some practice. However, I found an easier way, and one that's more consistent. Get together with your partner. Grab his or her hand... and compare them. Everyone has probably a ton of various length on your finger joints. For instance, the third knuckle to the tip of your middle finger may be exactly the same length as the third knuckle to tip of your partner's pinky! Just find two joints on your hands that are as close to exactly the same length as possible. Then, when you're writing, you can use that as your standard. Count off and, for instance, that lego is 3.5 joints away from the set of K'nex. Just remember which you're supposed to be measuring with. The key here is to have steady hands... at least steady enough to make sure you don't actually touch the structure when you're writing. You can always guesstimate by hovering your hand a little above the table rather than touch it and risk a DQ.

4. This fourth idea is possibly the most SECRETIVE in the event, so pay attention. It's one that's not always obvious, but will save you a LOT of time when writing. Go back and read the rules. You can't use abbreviations. You can't use secret symbols. It says nothing about proper grammar. Put your IM and texting skills to good use. Don't use any words that aren't necessary. For instance, rather than saying "Place a long gray K'nex piece vertically on the table in the 12:00 - 6:00 position." Think about "Gray stick 12:00-6:00" Conveys exactly the same idea, your partner will understand (especially after practicing), and you just save a ton of time writing. The key here is figuring out what is necessary to include and what is fluff you can remove without confusing your partner or leaving out key descriptions. Here could be a description though:

White K'nex piece flat on table. Out of 12:00 slot gray stick, 4:30 - red stick, 9:00 - white stick. Connected on other end of gray stick, red piece, extra slots on left. From middle slot in red piece, another gray stick coming out at 7:30.

Basically, the lesson you should get is, don't worry about proper grammar. You can't abbreviate words, but you CAN completely omit words you don't need. Save yourself as much time as possible. You'd be amazed at how much time you can save with such a simple concept.

It will also help a lot if you re read the instructions written by your partner if you are the builder just to make an adjustments before you are finished


The absolute best way to prepare for this event is to practice - a lot. Fortunately, this is usually a lot of fun. The first thing to do is find a bunch of practice materials. See if you or anyone on your team has building toys. Things like legos, Tinkertoy, Lincoln logs, construx, googleplex, k'nex and the like that are good. Don't rule out a paper one (with cut outs glued in a way on a sheet of paper, they are HARD.) Also practice with craft materials(Colorado does nothing else) like styrofoam with stuff in it such as pins, straws, fake flowers, bent paperclips and such. Also try pipe cleaners, bead, Cd's ANYTHING. If you have a budget, go shopping (although most people sometime in their life played with things like this)! Try to find things that have different ways of fitting together (aka: connects! they connect in some crazy ways man!). You can also use things you find around a science classroom, such as molecule builder sets. Try things like toothpicks and jellybeans, too; if you can write good instructions for them, you're in pretty good shape. Challenge yourself!

Once you have a stash of building materials, practice as often as possible. Find another teammate or someone to build for you. (Before you start, make sure you have duplicates of every piece used in the construction.) If it's your first time, you might want to start small, with perhaps no more than twenty pieces. Try find a quiet, secluded place to do your practice runs. You should keep the original construction and compare it to the one you and your teammate produce. Go over the written instructions together, and find places that were unclear or misleading. Talk about what the directions meant and how you interpreted them. If you were writing, describe your thought process and which things you were unsure about. If you were building, be sure to mention any problems you encountered following the directions - did your structure fall apart repeatedly? Did you find yourself trying to make the pieces do something physically impossible?

You should try and practice as many different ways as possible. Even if you know who will be writing and who will be doing, you should take turns practicing each different role. It really helps if you understand both parts of the process. (Plus it's fun!) On most runs you should stick exactly to the given times, so you learn how to work against the clock. However, if you find yourself consistently running out of time, do a few practices where you just work until you finish, no matter how long it takes you. Then you can work on cutting your time down. Work with all the different materials you can find. It's always nice when you get to the competition and your structure is made out of something you've already worked with before, but if it's something completely new you'll be better equipped to handle it if you've practiced with diverse materials. You might even try working with more than one type of material at once. At that same 99 national Olympiad, the main structure was made of legos (mostly itty bitty legos), but it also had a bunch of little plastic toys incorporated into it. Practice writing on lined paper and unlined paper (you never know what they'll give you, and not all judges will let you bring your own paper). Work under different conditions - sitting at a desk, standing at a lab bench, and so forth. Practice not touching the structure while you write. You might have to share it with other writers! If you need to get a different perspective, walk around it and look at it from the other side. It will be very helpful to you if you learn to visualize the object from different angles without actually moving it around yourself.

Also try on oral WIDI very fun. Put up a screen between the writer and doer. Give the writer a model and the doer the parts and have at it. just start talking to doer on how to build it. Doer feel free to talk back. It helps work out problems in the future,

Once you find that you and your teammate are consistently doing well and producing structures that are identical or nearly so to the originals, find ways to make things harder. Add more pieces. Ask the people building for you to make them as complicated and asymmetrical as possible. Have them build so that you have pieces in more than just two or three different planes. When you separate your pieces into two sets, add some extra ones to the set that will be used for doing. Get your builders to work in trick pieces - one of the most common (and deceptive!) tricks with legos is to use several pieces of the same color together so that they look like a single lego brick. You don't have any advantage for finishing your writing early, so you should always use the entire twenty five minutes. If you finish early, go back and check and make sure you didn't write anything you didn't mean. However, time can be used as a tiebreaker in the doing section. If you and another team have the same number of correct connections, the team that finished building first gets a better score. So, try and work as fast as you can without sacrificing accuracy.

Most of all, have fun. This event is one of the absolute best ones to prepare for - you get to play with toys! And the more you practice, the more you'll feel confident in both yourself and your partner.
