Step 3: Transfer the Design

I demonstrate using the graph paper by having a labyrinth design of my own. I tape it to the MDF than put a piece of carbon paper under it.

Use the ruler and pencil to draw in all of the drill holes. Than i usually get a sharp piece of wood and use it to (invisibly) draw a big smiley face.

I ask the kids if they wan to see whats under the page so i lift it and they see the big smiley face. They LOVE it. Easily impressed i tell you.

Than i start drawing all the walls that are vertical... checking once in a while to check progress. Once i get all the vertical lines done i do all the horizontal lines.

once the drawing is done i pull off the paper and remind them to NOT throw away the design. It is worth 10% of their grade. This motivates some kids to keep work...

Stu, I used marbles instead of a ball bearing because they are cheaper and easier to get. I used luan plywood because it is cheap. The rest was mostly pine boards ripped to size. Here are a pic of a few mazes. Joe
Any recommendations for the best type of paint you used?
<p>I used craft paint from WalMart</p>
AWESOME. &quot;the lost mine of diablo&quot; :-) love it. <br>I tried marbles but had a tough time finding ones with consistent sizes and shape... they would tend to roll all weirdly around the maze. Where did you get yours?
I got mine at WalMart. They come in a bag of 50 mixed in several sizes, but I found that to be a plus; sometimes you need a smaller marble when the kids mis-measure. The ones I got seem to be consistant in shape. The only problem with marbles is that they sometimes chip when they hit the concrete shop floor. But they are cheap. so I do not mind replacing a few.<br><br>Thinking about trying your gumball machine next. Your plan seems to be easier to build than most. My biggest problem is my small budget...so I have to carefully select projects that are not budget-busters.
good point with the different sizes. I'll try marbles next time... the bearings can get expensive and they mean about 45 minutes of driving.. :-) <br>The gumball machine is REALLY popular with the kids. They love it. If you keep your eyes open the 4x4 stuff gets thrown out often. If you find the Jars and lids buy as much as you can because they are seasonal. Often they can be found at Thrift stores for next to nothing! I can relate to the budget thing. 2 years ago we lost 14 staff due to &quot;cutbacks&quot;... our province doesn't seem to value kids much. Real shame. Be sure to send pics when the gumball machines are done!<br>-stu
Just finished having my 7th and 8th graders make these mazes. I was surprised at how much they got into the project. I made a few modifications in materials and made them come up with a &quot;theme&quot; to their puzzles. Thanks for the idea.
Glad to hear it worked for you! I like the idea of a theme. Do you have any pics?<br>thanks for the feedback!<br>-stu
That is a superb project, and very detailed. Thanks for sharing! Favorited it for future builds with my kiddo :)
Great! thanks for commenting... I'd love to see what you build... send it my way!
This is excellent. Great incorporation of learning objectives into an awesome project.
